A reference point calculation module for calculating the coordinate value of the reference point of the held object;
In order to detect the presence or absence of a drag operation, a distance between the mouse down coordinate value and the mouse move coordinate value (hereinafter referred to as a movement distance) is calculated, and a movement distance calculation module for storing the history in a history storage area is provided. To do.
Then, the mouse down analysis process, the mouse move analysis process, and the mouse up analysis process shown below are performed, and the hold object is not included in the process, and the distance is not less than a certain distance (out of the preparation range). (D) Detect edit data when a drag operation occurs as an activation event.

  The mouse down analysis process (including the mouse move analysis process (see FIG. 2)) is triggered by an event generated by the mouse up operation or the mouse move operation. The coordinate value of the position of the drawing pointer when the mouse is down ( A position detecting step for detecting mouse down coordinate value: edit data), and an object existing within the specified range of the position indicated by the mouse down coordinate value is detected in the graphic storage area or the guide storage area by the object search module. The hold determination step (including an object search step; the same applies hereinafter) for determining whether there is an existing object that can be searched from the object and can be held by the drawing pointer, and held by the drawing pointer by the object determination module Object attribute of the object The processing target, and the object determination step of determining an input object ID, and the processing contents), they, and performs determination step and processing step of performing processing according to the determination results of both steps.

  In the hold determination step, if the object does not exist within the specified range of the position indicated by the mouse down coordinate value, the coordinate value of the position of the drawing pointer moved by the mouse move operation (hereinafter referred to as the mouse) is determined by the mouse move analysis process. The mouse down analysis process is terminated through processing steps such as output of the move coordinate value (edit data) and the object ID of “graphic” (see FIG. 2).

  In the hold determination step, if an object exists within the specified range of the position indicated by the mouse down coordinate value, the movement distance calculation module further calculates the movement distance of the drawing pointer and finishes moving by the mouse move operation. The distance calculation step in the mouse move analysis process for determining whether or not the position of the drawing pointer is more than a set value from the position indicated by the mouse down coordinate value is performed.

  When it is determined that the distance calculation step is less than the specified value, the mouse down analysis process is terminated through a processing step of outputting a mouse down coordinate value and an object ID of “graphic”. On the other hand, when it is determined that the distance calculation step exceeds the specified value, an object determination step is further performed to determine whether the object held by the drawing pointer is a “point” or another object.

  When the object held by the drawing pointer is found by the object determination step, the following processing is performed by the object editing module of the guide drawing means.

  That is, when the object held by the drawing pointer is “point”, a tool setting step for setting a flag for performing “compass” processing is performed. Then, with the position [DOWN] of the mouse down coordinate value as the center, the moving distance between the mouse down coordinate value and the mouse move coordinate value as a radius, and the position that has reached the specified value in the process of reaching the moving distance, Using the object editing module, edit the "line segment" that matches the operation, with the start point on the straight line connecting the center and the end point on the straight line connecting the mouse move coordinate value and the center. Then, the line segment data is received from the object editing module, positioned as “LINE”, displayed by the object display module, and the mouse down analysis process is terminated.

  On the other hand, when the object held by the drawing pointer is not a “point”, the object is regarded as a “line segment”, and whether or not the rotation processing is desired is determined by whether or not the shift key is pressed. Go through the steps. If the shift key is pressed in the object determination step, a flag for performing the “protractor” process is set. On the other hand, if it is not pressed, a flag for performing the “parallel ruler” process is set.

  In the “protractor” process, a point search step for searching whether or not “point” or “intersection” exists on or near the “line segment” held by the drawing pointer is performed. If they exist, center on the “point” or “intersection”, and if they do not exist, center on the foot of the perpendicular line down to the “line segment” from the position of the mouse move coordinate value. A copy of the “line segment” adapted to the operation rotated to an angle connecting the position of the mouse move coordinate value is formed by an object editing module, displayed as “LINE” by the object display module, The mouse down analysis process is terminated.

  In the “parallel ruler” process, a copy of the “line segment” adapted to the operation translated to the position of the mouse move coordinate value is formed by the object editing module, and is positioned as “LINE”. Display by the object display module, and the mouse down analysis process is terminated.

  The mouse up analysis process (including the mouse move analysis process (see FIG. 3)) is started with the mouse up operation as a trigger, and the coordinate value (mouse up coordinate value: edit data) of the position of the drawing pointer where the mouse is up is displayed. A position detecting step for detecting, a hold determining step for determining whether or not the object exists within a specified range of the position indicated by the mouse-up coordinate value by the object search module, and an object attribute of the held object ( The object determination step for determining the processing target, the input object ID, and the processing content), and the determination step and the processing step for performing processing according to the determination results of these two steps are performed.

  If there is an object at the position indicated by the mouse-up coordinate value in the hold determination step, the mouse-up analysis process is terminated through a processing step of outputting the mouse-up coordinate value and the “graphic” object ID.

  In the hold determination step, if there is no object at the position indicated by the mouse up coordinate value, the movement distance calculation module further moves the drawing pointer by the mouse move operation (the mouse up coordinate value indicates The distance calculation step in the mouse move analysis process for determining whether or not (position) is more than a predetermined value from the position [DOWN] of the coordinate value of the mouse down is performed.

  If it is determined that the distance is less than the specified value in the distance calculating step, whether or not the moving distance is more than the specified value during the period from the last mouse down to the mouse up by the moving distance calculation module. It goes through a history reference step for determining by referring to the history in the history storage area. If there is no such record, the mouse-up analysis process is terminated through a processing step of outputting the mouse-down coordinate value and the “graphic” object ID. On the other hand, if it is determined in the history reference step that there is a record that exceeds the specified value, the mouse-up analysis process is immediately terminated.

  When it is determined that the distance is not less than the specified value in the distance calculating step, an object search step for detecting an object existing within the specified range from the mouse up coordinate is performed. If the object detected by the object search step is a point, the point is the [UP] coordinate, and if the object detected by the object search step is a “line”, the mouse up coordinate The vertical line of the line segment is taken as the [UP] coordinate, and when there is no object detected by the object search step, the position of the mouse up coordinate value is taken as the [UP] coordinate.

  The object editing module records the distance between the position [DOWN] of the mouse down coordinate value obtained by the mouse down analysis process and the [UP] coordinate, and the relative rotation angle thereof, in the history of the movement distance calculation module. Based on the above, the edit setting module displays an input dialog with these values as initial values on the display, prompting the operator to input the set value, and performing the input operation and confirming the input dialog The numerical value setting step is closed (see FIG. 3).

  That is, when the confirmation of applying the input value in the numerical value setting step is obtained, the position [DOWN] of the mouse down coordinate value is set as a fixed point, and the position is moved or rotated by the set numerical value in the [UP] coordinate direction. Are formed by an object editing module, the line segment data is received from the object editing module, positioned as “LINE”, displayed by the object display module, and guided by the guide drawing means. It goes through a processing step of saving in the save area. On the other hand, if the confirmation of applying the input value is not obtained, the mouse-up analysis process is immediately terminated and the state immediately before the series of editing flows is restored (see FIG. 3).

  Hereinafter, taking the drawing process of a straight line as an example, the use of auxiliary lines, that is, both the graphic drawing means and the guide drawing means function (the auxiliary line notification is on (see FIG. 7)), that is, the guide drawing. A basic example of the processing operation of the graphic creation device on the premise that the means can be used.

  First, when moving to the drawing start point, the drawing pointer is moved by the operation of the mouse that is moved without the mouse button being operated, and a MOVE event is generated in the input means (see the first row in FIG. 11).

  Next, the DOWN event is generated when the mouse down operation in the first editing process is performed at a position desired by the operator, and the editing data is provided via the input switching means (the configuration without the input switching means is also possible). Is output as editing data of the editing means that is an input destination as an initial condition (see the second row in FIG. 11). In the editing means that has received the editing data of the mouse down operation, the input analysis module functions to perform the mouse down analysis process (see FIG. 4).

  Here, it is assumed that there is no object that can be held by the drawing pointer within the specified range from the position indicated by the mouse-down coordinate value (hold determination step (including object search step) by the object search module). .) Then, the edit data including the mouse down coordinate value detected by the mouse down analysis process in accordance with the mouse down operation of the operator and the object ID of “graphic” is output to the input switching means (see FIG. 2).

  On the other hand, if there is an object that can be held by the drawing pointer within the specified range from the position indicated by the mouse down coordinate value (hold determination step), the mouse move analysis process causes the mouse to move from the position of the mouse down coordinate value. It is determined whether or not the distance (movement distance) to the position where the move operation (drag operation) is performed is greater than or equal to a specified value (distance calculation step), and if the movement distance is less than the specified value, Edit data including the mouse down coordinate value and the object ID of “graphic” is output to the input switching means.

  The input switching means receives the edit data including the mouse down coordinate value and the object ID of “graphic” and refers to a control table (see FIG. 7), and the edit data indicates the graphic drawing means indicated by the edit data. And processed as editing data of the graphic drawing means.

  Next, an UP event is generated by moving the mouse up to a position desired by the operator, and the editing means which is the input destination as an initial condition is also possible via the input switching means (a configuration without the input switching means is also possible). The edited data is output. In the editing means that receives the editing data of the mouse up operation, the input analysis module functions and performs the mouse up analysis processing.

  Here, there was no object that could be held with the drawing pointer within the specified range from the position indicated by the mouse-up coordinate value (hold determination step), and thus it was detected by the mouse-up analysis process in response to the operator's mouse-up operation. Edit data including the mouse up coordinate value and the object ID of “graphic” is output to the input switching means.

  The input switching means receives the edit data, refers to the control table (see FIG. 7), outputs the edit data to the graphic drawing means, and handles the edit data as edit data of the graphic drawing means. It is.

  In the graphic drawing means, the object determination module receives the edit data and refers to the control table (see table in FIG. 8), and is determined as a “point” based on the reference result. The object edit module displays the object display The module is displayed as the start point of the “line segment” that is the object to the mouse down coordinate (see the third row in FIG. 11), and the mouse save coordinate is displayed as the start point of the “line segment” by the object storage module. Saved to the save area. The mouse-up analysis process is completed through the object storage step, and the first editing process (editing the first point of drawing) is completed.

  Subsequently, when moving to the next drawing start point, a MOVE event is generated by the operation of the mouse that moves without the mouse button being operated. Upon receiving the MOVE event, the object editing module displays an image in which the drawing pointer moves by drawing a straight line drawn from the start point on the display using the object display module, and the object storage module displays the start point and The extracted line segments are sequentially stored in the graphic storage area, and the mouse move analysis process continues (see the fourth row in FIG. 11).

  Next, the DOWN event occurs when the mouse down operation of the second editing process is performed at a position desired by the operator, and the configuration is possible via the input switching means (the configuration without the input switching means is also possible). The edit data is output as edit data of the editing means that is the input destination as the initial condition (see the fifth row in FIG. 11). In the editing means that has received the editing data of the mouse down operation, the input analysis module functions and the mouse down analysis process is performed (see FIG. 5).

  Here, there is an object that can be held by the drawing pointer within a specified range from the position indicated by the mouse-down coordinate value (hold determination step), and the presence of a “(vertical) line segment” is recognized in the guide storage area. Therefore (hold determination step), by the reference point calculation module, the coordinates of the foot of the perpendicular line that is lowered to the “line segment” from the position of the mouse down coordinate value detected by the mouse down analysis process in accordance with the mouse down operation of the operator is obtained. Calculated and output as a nearby point (grip point: starting point for the following moving distance calculation) coordinates, and output the editing data including the output near point coordinates and the object ID of “guide” to the input switching means. Is done.

  The input switching means receives the edit data, refers to the control table (see FIG. 7), and outputs it to the guide drawing means indicated by the edit data. The edit data is used as edit data of the guide drawing means. Handled.

  When the mouse down operation of the second editing process is performed and the mouse move operation is continuously performed, a move event is generated, and the editing data given through the input switching means continues to the initial condition. Is output as editing data for guide editing in the editing means as the input destination, and drawing drawing editing is interrupted by the first editing step. In the editing means that receives the editing data of the mouse move operation, the input analysis module functions and the mouse move analysis process is performed.

  In the mouse move analysis process, the distance (movement distance) from the position indicated by the neighboring point coordinates to the mouse move coordinate value is calculated (distance calculation step by the movement distance calculation module), and the movement distance is within a specified value. No new editing operation is performed as a guide drawing preparation state, and the drawing / drawing state at the end of the first editing step is maintained (see the sixth row in FIG. 11). On the other hand, if the value is equal to or greater than the specified value, the drag operation is recognized and the following processing is performed.

  In addition, the object determination module determines the object held by the drawing pointer (object determination step). In this example, since it is a “line segment” other than “point” as described above, a shift key is further displayed. It is determined whether or not it is pressed. When the shift key is not pressed, the object editing module sets a “parallel ruler” flag (tool setting step), and a line equal to the translation of the grip point of the “line segment” to the mouse move coordinate value. The object is displayed on the display by the object display module, and is sequentially stored in the storage area as “LINE” existing at the position where the “parallel ruler” process is continued by the object storage module, and the mouse move analysis process Continues (see the last stage in FIG. 11).

  Next, an UP event is generated by performing the mouse up operation at a position desired by the operator (see the first row in FIG. 12), and the mouse up is sent to the editing means which is the input destination as an initial condition via the input switching means. Edit data by operation is output. In the editing means that has received the editing data, the input analysis module functions and performs the mouse up analysis processing (Case A).

  In the mouse-up analysis process, it is searched whether there is an object that can be held by the drawing pointer within the specified range from the position indicated by the mouse-down coordinate value (object search step). Here, the object is held by the drawing pointer. The object determination module determines the object held by the drawing pointer by the object determination module (object determination step), and the object editing module has the flag “parallel ruler” set, In addition, it is confirmed that the movement distance of the drawing pointer when the UP event occurs is a predetermined value or more (distance calculation step), and the “line segment” being dragged from the mouse up coordinate value detected by the mouse up operation of the operator The distance to the foot of the perpendicular to and relative The turning angle is digitized based on the history of the moving distance calculation module, and the edit dialog module displays an input dialog with these numerical values (setting numerical values) as initial values (see the second row in FIG. 12). A numerical value setting step for prompting the input of a set value and closing the input dialog by an input operation and an operation for confirming the application is performed (see the third row in FIG. 12).

  The distance (movement distance) from the position of the mouse down coordinate value to the position where the mouse move operation (drag operation) is performed by the mouse move analysis process when the application confirmation operation is not performed or the cancel button is operated ) Is greater than or equal to a specified value (distance calculation step), and if the moving distance at the time of the UP event is less than the specified value, drawing is performed within the specified range from the position indicated by the mouse down coordinate value. Even if there is an object that can be held by the pointer (hold determination step), a cancel process for returning to the drawing / drawing state at the end of the first editing process, that is, before the start of the series of editing flows (Case B) (See the sixth row in FIG. 11 and FIG. 13).

Based on the set numerical value entered in the input dialog, the object display module performs the process given to the condition that the “parallel ruler” flag is set (“parallel ruler” process). In addition to the drawing / drawing state at the end of the editing process, the “line segment” is displayed by the object display module from the position indicated by the neighboring point coordinate value to a position corresponding to a set numerical value, and the object display module. The data is stored in the guide storage area as “LINE” existing at the position where the “parallel ruler” processing is completed by the storage module. The mouse-up analysis process is completed through the object storage step, and the second editing process (moving copy of “line segment” as a guide) is completed (see the third row in FIG. 12).

  Upon completion of the second editing process, the drawing drawing state at the end of the first editing process is restored. Then, when moving to the next drawing start point, a MOVE event is generated by the operation of the mouse that moves without operating the mouse button. Upon receiving the MOVE event, the object editing module displays an image in which the drawing pointer moves by drawing a straight line drawn from the start point on the display using the object display module, and the object storage module displays the start point and The extracted line segments are sequentially stored in the graphic storage area, and the mouse move analysis process continues (see the fourth row in FIG. 12).

  Furthermore, the DOWN event occurs when the mouse down operation in the third editing process is performed at a position desired by the operator, and the editing is possible via the input switching means (the configuration without the input switching means is also possible). The data is output as editing data for guide editing in the editing means that is the input destination as the initial condition (see the fifth row in FIG. 12). In the editing means that has received the editing data of the mouse down operation, the input analysis module functions and the mouse down analysis process is performed.

  Here, the object that can be held by the drawing pointer within the specified range from the position indicated by the position of the mouse down coordinate value by the hold search step by the object search module and the object determination step by the object determination module is determined as a point, an intersection, a line The figure storage area and the guide storage area are searched in the order of minutes. In this example, the “intersection” between the “LINE” and the existing “LINE” is detected preferentially, and when the mouse down coordinate value (with the process of adsorbing to the “intersection” in the specified area) is involved, The intersection point calculation module calculates the coordinate value of those “intersection points”, and edit data including the coordinate value of the “intersection point” (intersection point coordinate value) and the object ID of “graphic” is output to the input switching means. .

  The input switching means receives the edit data including the intersection coordinate value and the object ID of “graphic” and refers to the control table (see FIG. 7), and the edit data is sent to the graphic drawing means indicated by the edit data. Is output and handled as editing data of the graphic drawing means.

  Next, an UP event is generated by moving the mouse up at a position desired by the operator, and the editing means that is the input destination as an initial condition is possible via the input switching means (a configuration without the input switching means is also possible). The edited data is output (see the last stage in FIG. 12). In the editing means that receives the editing data of the mouse up operation, the input analysis module functions and performs the mouse up analysis processing.

  Here, since the “intersection” is detected within the specified range indicated by the mouse-up coordinate value by the object search module and the object determination module, the object detected by the mouse-up analysis process accompanying the mouse-up operation of the operator is detected. Edit data including the intersection coordinate value and the object ID of “graphic” is output to the input switching means.

  The input switching means receives the edit data, refers to the control table (see FIG. 7), outputs the edit data to the graphic drawing means, and handles the edit data as edit data of the graphic drawing means. It is.

  The graphic drawing means receives the edit data, refers to the control table (see FIG. 8), and has two points based on the reference result and one point obtained in the first edit step. The object editing module displays the end point of drawing and the “line” connecting the start point and the start point to the mouse down coordinate by the object display module, and the mouse is stored by the object storage module. The down coordinate is stored in the graphic storage area as the end point of the “line” as the graphic drawing object, and the “line” is stored as one of the graphic drawing objects. The mouse-up analysis process is completed through the object storage step, and the third editing process (editing of the first point of drawing) is completed (see the last stage in FIG. 12).

Next, another processing mode in which editing is performed using an existing object as in the second editing process will be described.
The process shown in FIG. 14 shows an example of a process of rotating an existing line segment by a desired angle (hereinafter referred to as “rotary copy” process (case C)).

  The DOWN event is generated by performing a mouse-down operation in the “rotary copy” processing process at a position desired by the operator, and the editing data can be configured via the input switching means (the configuration without the input switching means is also possible). Is output as editing data of the editing means that is the input destination as the initial condition (see the first row in FIG. 14). In the editing means that has received the editing data of the mouse down operation, the input analysis module functions and the mouse down analysis process is performed (see FIG. 5).

  Here, there is an object that can be held by the drawing pointer within the specified range from the position indicated by the coordinate value of the mouse down (hold determination step), and the “(vertical) line segment (dotted line display in FIG. 14) is displayed in the guide storage area. ) ”Is recognized (hold determination step), the reference point calculation module changes the mouse down coordinate value detected by the mouse down analysis process to the“ line segment ”from the mouse down operation processing. Calculates the coordinates of the foot of the dropped perpendicular and outputs it as a nearby point (grip point: starting point for the following moving distance calculation), and also includes the coordinates of the proximity point thus output and the object ID of the “guide” Data is output to the input switching means.

  The input switching means receives the edit data, refers to the control table (see FIG. 7), and outputs it to the guide drawing means indicated by the edit data. The edit data is used as edit data of the guide drawing means. Handled.

  When a mouse down operation is performed in the rotational copying process and a mouse move operation is continuously performed, a move event is generated, and a configuration without an input switching unit is also possible. ) The given editing data is continuously output as editing data for guide editing in the editing means as an input destination as an initial condition, and the editing is performed according to the drawing / drawing state before the start of the series of editing flows. The process is interrupted. In the editing means that receives the editing data of the mouse move operation, the input analysis module functions and the mouse move analysis process is performed.

  In the mouse move analysis process, the distance (movement distance) from the position indicated by the neighboring point coordinates to the mouse move coordinate value is calculated (distance calculation step by the movement distance calculation module), and the movement distance is a specified value (in FIG. 14). If it is within the broken line circle (the same applies hereinafter), no new editing operation is performed as the guide drawing preparation state, and the drawing / drawing state before the start of the series of editing flows is maintained (six steps in FIG. 11). See eye). On the other hand, if the value is equal to or greater than the specified value, the drag operation is recognized and the following processing is performed.

  That is, the object determination module determines the object held by the drawing pointer (object determination step). In this example, since the line segment is not “point” as described above, the shift key It is determined whether or not it is pressed. When the shift key is pressed, the object editing module sets a “protractor” flag (tool setting step), and if the drag direction is within a certain threshold angle from the horizontal direction, along with the neighboring points, A line segment equivalent to the translation of the “line segment” to the mouse move coordinate value is derived, displayed on the display by the object display module, and present at the position where the “protractor” process is continued by the object storage module. "LINE" is sequentially stored in the storage area, and the mouse move analysis process continues (see the broken line in the first row in FIG. 14).

  When the “protractor” flag is set as described above (tool setting step), the object editing module causes the drag direction to exceed a certain threshold angle from the horizontal direction following the parallel movement. In this case, the position of the mouse-down coordinate value is set as the “center” of rotation (see FIG. 2), and the “line segment” existing at the position of the mouse-down (at the time of holding), together with the grip point, A line segment equivalent to the rotational movement by an angle exceeding the threshold angle is derived, displayed on the display by the object display module, and “LINE” existing at the position where the “protractor” processing is continued by the object storage module. Are sequentially stored in the storage area, and the mouse move analysis process continues (see the second dashed line in FIG. 14).

  At this time, if the shift key is released during the continuation of the mouse move analysis process, the object editing module sets a “parallel ruler” flag (tool setting step), and the “line” along with the neighboring points. A line segment equal to the value obtained by translating the “minute” to the mouse move coordinate value is derived, displayed on the display by the object display module, and “LINE” existing at the position where the “protractor” processing is continued by the object storage module. And the mouse move analysis process continues (see the third row in FIG. 14). Further, when the shift key is pressed, the object editing module sets the “protractor” flag again (tool setting step), and returns to the “rotational copying” process.

  Next, a UP event is generated by performing a mouse up operation at a position desired by the operator, and edit data by the mouse up operation is output to an editing unit which is an input destination as an initial condition via the input switching unit. . In the editing means that has received the editing data, the input analysis module functions and performs the mouse up analysis processing.

  In the mouse-up analysis process, it is searched whether there is an object that can be held by the drawing pointer within the specified range from the position indicated by the mouse-down coordinate value (object search step). Here, the object is held by the drawing pointer. The object held in the drawing pointer by the object determination module is determined (object determination step), and the object editing module sets the “protractor” flag, and Confirm that the movement distance of the drawing pointer when the UP event occurs is greater than or equal to a specified value (distance calculation step), and move from the mouse-up coordinate value detected by the operator's mouse-up operation to the “line segment” being dragged Distance to the foot of the perpendicular and relative turn The angle is digitized based on the history of the moving distance calculation module, and the edit setting module displays an input dialog with these numeric values (set numeric values) as initial values, prompting the operator to input set values (FIG. 14). A numerical value setting step for closing the input dialog is performed by an input operation and an application confirmation operation.

Based on the setting value entered in the input dialog, the object display module performs a series of editing flows by performing processing (“rotational copying” processing) given to the condition that the “protractor” flag is set. In addition to the drawing / drawing state before the start, the “line segment” is displayed by the object display module at a position rotated by an angle corresponding to a set numerical value from the position indicated by the neighboring point coordinate value, and the object is saved. It is stored in the guide storage area as “LINE” existing at the position where the “rotational copy” processing is completed by the module. The mouse-up analysis process is completed through the object storage step, and a series of editing flows accompanying the “rotation copy” process (rotation copy of “line segment” as a guide) ends.

  Upon completion of the “rotary copy” process, the drawing drawing state before the start of the series of editing flows is restored. Then, when moving to the next drawing start point, a MOVE event is generated by the operation of the mouse that moves without operating the mouse button. Upon receiving the MOVE event, the object editing module displays an image in which the drawing pointer moves by drawing a straight line drawn from the start point on the display using the object display module, and the object storage module displays the start point and The extracted line segments are sequentially stored in the graphic storage area, and the mouse move analysis process continues (see the bottom row in FIG. 14). Note that the cancellation process also accompanies the process.

  The process shown in FIG. 15 shows an example of a process for editing an arc having a desired radius by a desired angle (hereinafter referred to as “arc drawing” process (case D)).

  The DOWN event is generated by performing a mouse down operation in the “arc drawing” process step at a position desired by the operator, and the editing data can be configured via the input switching means (the configuration without the input switching means is also possible). Is output as editing data of the editing means that is the input destination as the initial condition (see the first row in FIG. 15). In the editing means that has received the editing data of the mouse down operation, the input analysis module functions and the mouse down analysis process is performed (see FIG. 5).

  Here, there is an object that can be held by the drawing pointer within the specified range from the position indicated by the mouse-down coordinate value (hold determination step), and the presence of an “intersection” is recognized in the guide storage area (hold). In the determination step), the reference point calculation module outputs the “intersection” as a base point coordinate of the “arc drawing” process from the position of the mouse down coordinate value detected by the mouse down analysis process in accordance with the mouse down operation of the operator, The edit data including the base point coordinates output in this way and the object ID of “Guide” is output to the input switching means.

  The input switching means receives the edit data, refers to the control table (see FIG. 7), and outputs it to the guide drawing means indicated by the edit data. The edit data is used as edit data of the guide drawing means. Handled.

  When a mouse down operation is performed in the rotational copying process and a mouse move operation is continuously performed, a move event occurs, and the editing data given through the input switching means continues as an initial condition. Is output as editing data for guide editing in the editing means that is the input destination, and the editing process is interrupted by the drawing / drawing state before the start of the series of editing flows. In the editing means that receives the editing data of the mouse move operation, the input analysis module functions and the mouse move analysis process is performed.

  In the mouse move analysis process, the distance (movement distance) from the position indicated by the base coordinate to the mouse move coordinate value is calculated (distance calculation step by the movement distance calculation module), and the movement distance is a specified value (broken line in FIG. 15). If it is within the circle (hereinafter the same), no new editing operation is performed as the guide drawing preparation state, and the drawing / drawing state before the start of the series of editing flows is maintained (second stage in FIG. 15). And the third row). On the other hand, if the value is equal to or greater than the specified value, the drag operation is recognized and the following processing is performed.

  That is, the object held in the drawing pointer by the object determination module is determined (object determination step), and in this example, since it is an “intersection” and a “point” as described above, the object editing module A flag that compasses is set (tool setting step), and when the movement distance reaches a specified value, a line that connects the point where the drawing pointer exceeds the specified value (intersection with the dashed circle in FIG. 15) and the base point An arc with the radius from the base point to the position indicated by the mouse move coordinate value is defined as the arc start point, the extension point of the line connecting the position indicated by the mouse move coordinate value and the base point, and the end point of the arc. And display it on the display using the object display module, and the object storage module continues the “compass” process. Is sequentially stored into the storage area as the "LINE" at the position in the mouse move analysis process continues (see first stage of the four-stage and 16 in FIG. 15).

  Next, a UP event is generated by performing a mouse up operation at a position desired by the operator, and edit data by the mouse up operation is output to an editing unit which is an input destination as an initial condition via the input switching unit. . In the editing means that has received the editing data, the input analysis module functions and performs the mouse-up analysis process (continuation of Case D).

  In the mouse-up analysis process, it is searched whether there is an object that can be held by the drawing pointer within the specified range from the position indicated by the mouse-up coordinate value (object search step). Here, the object is held by the drawing pointer. The object held in the drawing pointer by the object determination module is determined (object determination step), and the object editing module sets a flag of “compass”, and Confirm that the movement distance of the drawing pointer when the UP event occurs is greater than or equal to a specified value (distance calculation step), and the distance from the mouse-up coordinate value detected by the operator's mouse-up operation to the base point, and the relative Rotation angle of the distance meter Based on the module history, the edit setting module displays an input dialog with these values (setting values) as initial values, and prompts the operator to input setting values (see the second row in FIG. 16). Then, a numerical value setting step for closing the input dialog is performed by an input operation and an application confirmation operation.

Based on the set numerical value entered in the input dialog, the object display module performs a series of editing flows by processing (“arc drawing” processing) given to the condition that the “compass” flag is set. In addition to the drawing drawing state before the start, the mouse move coordinates with the starting point of the arc as the extension line of the line connecting the point where the drawing pointer exceeds the specified value (intersection of the bottom broken line circle in FIG. 15) and the base point With the object display module, an arc having a radius from the base point to the position indicated by the mouse move coordinate value is displayed as an end point of the arc on the extension line of the line connecting the position indicated by the value and the base point, The object storage module stores the data in the guide storage area as “LINE” existing at the position where the “arc drawing” processing is completed. The mouse-up analysis process is completed through the object storage step, and a series of editing flows associated with the “arc drawing” process is completed.

  Upon completion of the “arc drawing” process, the drawing drawing state before the start of the series of editing flows is restored. Then, when moving to the next drawing start point, a MOVE event is generated by the operation of the mouse that moves without operating the mouse button. Upon receiving the MOVE event, the object editing module displays an image in which the drawing pointer moves by drawing a straight line drawn from the start point on the display using the object display module, and the object storage module displays the start point and The extracted line segments are sequentially stored in the graphic storage area, and the mouse move analysis process continues (see the bottom row in FIG. 16). Note that the cancellation process also accompanies the process.

  The graphic creation device according to the present invention repeats the editing process as described above, and shifts to the new editing work for the same type of object or the first editing of the new editing work for the different type of object by selecting with the menu button. In addition to exiting from the editing process mode when a transition to the process is performed, etc., as long as the editing mode is set, editing of a guide or editing of a figure can be performed as appropriate.

  As described above, the graphic editing apparatus according to the present invention analyzes the edit data input from the input means by the input analysis module and handles it as edit data of the graphic drawing means by the input switching means, or edits by the guide drawing means. Switch whether to handle as data. At that time, the input analysis module detects the presence of the hold object and the presence / absence of the drag operation over a certain distance by the hold determination step and the distance calculation step, and edit data for controlling the switching operation of the input switching means, and the coordinate value And attributes (edit data) are output (see FIG. 10).

  That is, as shown in FIGS. 2 and 3, when there is no hold object and the movement distance is equal to or greater than a specified value, the graphic drawing means functions as a graphic drawing mode, and the guide editing mode is performed by an editing operation avoiding the condition. Alternatively, the guide drawing means and the editing means function as the editing operation end mode, and a series of editing operations including a plurality of editing operations from the start to the end of the graphic editing or the guide editing are performed. After the editing flow has been incorporated and the series of editing flow related to the guide editing has been completed, the editing flow including the interruption process of returning to the editing operation in the drawing mode of the original figure is performed by operating the mouse or the cursor key. This is possible only by moving the drawing pointer and clicking operation or key input operation such as a return key.

  In the above embodiment, the input analysis module is provided attached to the editing means, but it may exist alone or may be attached to other functional means. In addition, functional means for performing various processes such as input means, editing means, graphic drawing means, guide drawing means, or input analysis module may be combined as appropriate accompanying the main functional means.

  At that time, the transition to and return to the editing flow through the interrupt processing is the direct editing operation as in the above embodiment, that is, the presence of the hold object held by the pointer in the input analysis module is detected. With the object search module and the movement distance calculation module that detects the presence or absence of a drag operation, the edit data when a drag operation occurs over a certain distance without the hold object is detected instead of being detected as a start event. Needless to say, a configuration may be adopted in which an additional key input is used as an activation event.

  The present invention adopts a drawing method that can perform an efficient and accurate editing operation with a continuous editing operation when executing a series of editing flows. Contributes to further improved workability.
