In addition, by specifying overlay display, a virtual plane can be displayed at a position corresponding to the overlay display. Also, by designating a plane object, a virtual plane can be displayed at a position corresponding to the plane object. For example, a virtual plane corresponding to the plane on which the plane object is drawn can be displayed. . In addition, by designating a device object, a virtual plane can be displayed at a position suitable for drawing related to the device object. Thus, the virtual plane can be displayed at a position desired by the user by a simple operation.

Therefore, the work can be efficiently performed using the virtual plane.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The embodiment of the present invention is not limited to the following embodiment, and can take various forms as long as they belong to the technical scope of the present invention.

  FIG. 1A shows a configuration of a known PC 1 that operates as a design support apparatus in the present embodiment. The PC 1 includes a display 10, an HDD 20, a CPU 30, a ROM 40, a RAM 50, an input device 60, and the like.

  The display 10 displays the video generated by the CPU 30 or the like based on the video signal. The input device 60 includes a keyboard, a mouse, and the like, and outputs a signal corresponding to an operation received from the user to the CPU 30. The ROM 40 is a read-only nonvolatile memory, and the HDD 20 is a readable / writable nonvolatile memory. In the ROM 40 and the HDD 20, programs and the like that are read and executed by the CPU 30 are stored in advance. The RAM 50 is a readable / writable volatile memory. When the CPU 30 executes a program stored in the ROM 40 or the HDD 20, the RAM 50 is temporarily stored, or work data is temporarily stored. It is used as a storage area for

  The CPU 30 reads the OS from the HDD 20 and executes it, and executes various programs recorded in the HDD 20 as processes on the OS. In this process, the CPU 30 receives a signal input from the input device 60, generates a video to be displayed on the display 10, and controls reading and writing of data to the RAM 50 and the HDD 20.

  The design support program of this embodiment is installed in the PC 1. The design support program is stored in the HDD 20 and is one of applications that are executed as a process on the OS. By operating the design support program, the PC 1 operates as a design support apparatus.

[Description of operation]
(1) Outline First, an outline of the operation of the design support program will be described. In the following description, it is described that the design support program performs processing, but it goes without saying that this means that the CPU 30 of the PC 1 operating according to the design support program performs processing.

  The design support program is configured as a CAD system for drawing design drawings for constructing various structures including buildings such as buildings and houses. The design support program generates a three-dimensional design drawing according to an operation received from the user via the input device 60. At this time, the design drawing being drawn is displayed on the display 10, and each position on the design drawing is represented by an x, y coordinate indicating a position on the horizontal plane and a z coordinate indicating a position in the height direction. The object to be designed by the design support program is described as a construction object.

  In addition, the design support program arranges a member (path object) that extends along a path instructed by the user in a three-dimensional space on the design drawing. Path objects include, for example, ducts that send air for air conditioning and ventilation, tubular members for supplying and discharging liquids such as water, refrigerant pipes that move refrigerant used in air conditioners, and water. A member that moves the fluid along a predetermined path, such as a spear to flow down, is conceivable.

  In addition, the design support program places a device object, which is a device provided in a construction, in a three-dimensional space on the design drawing. Examples of equipment provided in the construction include air-conditioning equipment installed on the ceiling and walls, and equipment installed around water such as sinks, washstands, bathtubs, toilets, and the like. The air conditioner is connected to a path object such as a refrigerant pipe or a duct. Also, devices installed around the water are connected to route objects such as water pipes and drain pipes.

In addition, the design support program arranges a planar object that is drawn on a plane such as, for example, a character, a symbol, a pattern, a mark, or a line, in a three-dimensional space on the design drawing.
Further, the design support program displays a design screen representing the design drawing as a stereoscopic image on the display 10, and the design screen is an overlay indicating information related to the design drawing in a state of being superimposed on the design drawing. The display is displayed. The overlay display may indicate information for supporting the design such as the position on the design drawing and the orientation of the design drawing.

  Hereinafter, the components of the design drawing and the overlay display are referred to as objects. The design support program displays at least four types of objects: a path object, a device object, a plane object, and an overlay display.

  Then, the design support program displays a plane image (virtual plane) at a position on the design drawing corresponding to the cursor position due to the mouse cursor being positioned in the object display area on the design screen. Note that the virtual plane may be transparent or translucent. The design support program accepts an input for drawing a design drawing via a virtual plane. Specifically, for example, routing of a route object (receiving a designation of a route of the route object from the user and arranging the route object along the designated route) is performed via a virtual plane.

(2) Virtual Plane Next, the display mode of the virtual plane will be described in detail. When the cursor position is in the display area of the route object, a virtual plane is displayed at a position corresponding to the cursor position. In particular, when the cursor position is on the display area of the side surface portion of the path object, the virtual plane is displayed in a state where a straight section including the cursor position in the path object extends on the virtual plane. In other words, the virtual plane is disposed in contact with the straight section and along the straight section. Hereinafter, the virtual plane displayed in such a case is referred to as a route virtual plane.

  As an example, the design screen 100 shows a design drawing in which prismatic ducts 110 (an example of a route object) bent in an L shape are arranged along a horizontal arrangement surface (FIG. 1B). . On the design screen 100, a height display 140 (an example of an overlay display) including numbers (6000, 5000, etc., unit: mm) indicating a plurality of positions in the height direction in the design drawing is displayed. When the mouse cursor 120 is positioned in the display area on the side surface of the duct 110, a virtual plane icon 130 is displayed. In FIG. 1B, as an example, when the cursor 120 is positioned on the lateral side surface of the short portion 111 of the duct 110, a virtual plane icon 130 is displayed. The virtual plane icon 130 is a planar icon (a small image composed of a picture, a symbol, or the like expressing a predetermined meaning), and indicates that the virtual plane can be displayed along the virtual plane icon 130. The design screen 100 is a three-dimensional image obtained by viewing the design drawing from an obliquely upper viewpoint. However, the position of the viewpoint is not limited to this, and the viewpoint may be changed according to an instruction from the user.

  At this time, when a predetermined operation is performed, a route virtual plane 150 that passes through the center of the duct 110 and is parallel to the arrangement surface is displayed on the design screen 101 (FIG. 1C). Hereinafter, the operation performed when the virtual plane icon is displayed is referred to as a display operation. The short part 111 of the duct 110 where the cursor 120 is located is in a state extending on the route virtual plane 150. The route virtual plane 150 extends in a direction intersecting the lateral side surface on which the cursor 120 is located.

  Note that the height of the route virtual plane 150 is not limited to this, and the route virtual plane 150 may be disposed so as to pass through the lower surface and the upper surface of the short portion 111, for example. The display operation may be, for example, an operation with a PC mouse. Specifically, the display operation is a mouse wheel (a disk-shaped part provided in the center of the mouse on the side where the buttons are arranged and used for scrolling the screen). ) May be clicked. Of course, not limited to this, other operations on the mouse or operations on the keyboard may be used as display operations. However, display operations are not used for drawing blueprints or are used less frequently. It is desirable to be an operation. Further, the virtual plane may be displayed according to the cursor being positioned in the display area of the route object without performing the display operation.

  When the user designates a route in the display area of the route virtual plane 150 with the cursor 120, the duct 110 is routed on the route virtual plane 150 according to the designated route. When the route virtual plane 150 is used, routing along the arrangement surface of the duct 110 can be easily and accurately performed. In routing, an angle hold function for switching the direction of the route at a predetermined angle (for example, 45 °) may be enabled.

  In addition, when a display operation is performed in a state where the cursor 120 is positioned in the display area of the upper side surface or the lower side surface of the duct 110, a route virtual plane extending in a direction intersecting with the upper side surface or the lower side surface where the cursor 120 is positioned is displayed. The As an example, on the design screen 102, the display operation performed in a state where the cursor 120 is positioned in the display area on the upper side surface of the short portion 111 of the duct 110 passes through the center line of the short portion 111 to the arrangement surface. An orthogonal route virtual plane 151 is displayed (FIG. 1D).

  Similarly, the duct 110 can be routed on the route virtual plane 151. As an example, the section 114 of the design screen 200 is generated by the routing (FIG. 2A). In routing using the route virtual plane 151, the vertical direction of the duct 110 can be easily and accurately changed.

  Further, when a display operation is performed in a state where the cursor 120 is positioned in the display area of the end portion of the duct 110 (the opening portion of the duct 110), a virtual plane orthogonal to the direction of the duct 110 is displayed adjacent to the end portion. The As an example, on the design screen 103, a virtual plane 152 orthogonal to the direction of the short portion 113 is displayed by a display operation performed with the cursor position positioned in the display area of the end portion 113 (FIG. 2 ( B)). In the routing using the virtual plane 152, a new section extending from the end of the short part 111 in the vertical and horizontal directions can be easily generated.

  Further, as described above, the virtual plane is also displayed when the cursor position is in the display area of the overlay display. The overlay display is displayed regardless of whether or not a virtual plane is displayed. The overlay display may be always displayed, or the presence / absence of the overlay display may be switched according to the user's operation. When the cursor 120 is positioned in any number display area constituting the height display 140 as an example of the overlay display, a horizontal virtual plane having the height indicated by the number is displayed. As an example, on the design screen 104, the virtual plane 153 is displayed by the display operation performed in a state where the cursor 120 is positioned in the display area of the number “2000” of the height display 140 (FIG. 2C). ).

  Further, the design support program displays a coordinate icon 160 composed of a pattern indicating the x-axis, the y-axis, and the z-axis as an overlay display according to an instruction from the user (FIG. 2D). Note that the x-axis, y-axis, and z-axis directions may extend in the x-axis direction, the y-axis direction, and the z-axis direction on the design drawing, respectively. When the cursor 120 is positioned in the display area of any axis, a virtual plane that is orthogonal to the axis and passes through the origin of the coordinate space of the design drawing is displayed. As an example, on the design screen 105, a virtual plane 154 that passes through the origin perpendicular to the x axis is displayed by a display operation performed with the cursor 120 positioned in the x axis display area of the coordinate icon 160. .

  Furthermore, the design support program automatically displays an adjustment icon for adjusting the position of the virtual plane after the virtual plane is displayed. And according to the instruction | indication received via the adjustment icon, the position of a virtual plane is adjusted.

  On the design screen 106 in FIG. 3A, a translation icon 170, which is an adjustment icon for translating the virtual plane 155, is displayed. The parallel movement icon 170 is configured as one arrow indicating one and the other of the virtual plane 155 in the vertical direction. As an example, the parallel movement icon 170 indicates an upward direction and a downward direction. Then, when an operation such as clicking is performed in a state where the cursor 120 is positioned in the display area of the arrow indicating one, the virtual plane 154 is translated in this direction, and the cursor 120 is positioned in the display area of the arrow indicating the other When an operation such as clicking is performed in the state, the virtual plane 154 moves in parallel in that direction.

  In addition, an inclination adjustment icon 180 that is an adjustment icon for adjusting the inclination of the virtual plane 156 is displayed on the design screen 107 in FIG. The tilt adjustment icon 180 is a circular icon arranged in a state drawn on the virtual plane 156, and four arrows extending radially are arranged at intervals of 90 °. Then, when an operation such as a click is performed in a state where the cursor 120 is positioned in any one of the arrow display areas, the virtual plane 156 is arranged so that the side indicated by the arrow is lowered about an axis orthogonal to the arrow at the cursor position. The slope of changes. As an example, the design screen 107 shows how the inclination of the virtual plane 155 changes when a click or the like is performed while the cursor is positioned in the display area of the first arrow 181 of the inclination adjustment icon 180. .

  In addition, on the design screens 300 and 301, cylindrical pipes 310 (an example of a path object) bent in an L shape are arranged along a horizontal arrangement surface (FIGS. 3C and 3). (D)). When the display operation is performed in a state where the cursor 320 is positioned in the display area on the side of the pipe 310 as in the design screen 300, the path imaginary parallel to the arrangement plane passing through the center line of the pipe 310 is the same as the duct 110. A plane 350 is displayed. Further, when the display operation is performed in a state where the cursor 320 is positioned in the upper or lower display area of the pipe 310, the virtual route is orthogonal to the arrangement plane passing through the center line of the section at the cursor position, like the duct 110. A plane is displayed. As an example, on the design screen 301, the display operation performed in a state where the cursor 320 is positioned in the display area above the short portion 311 of the pipe 310 passes through the center line of the short portion 311 and is orthogonal to the arrangement surface. A route virtual plane 351 to be displayed is displayed.

  The short part 311 of the pipe 310 is in a state extending on the route virtual planes 350 and 351. In addition, the route virtual plane 350 extends in a direction intersecting the side portion of the pipe 310 where the cursor 320 is located, and the route virtual plane 351 extends in a direction intersecting the upper portion or the lower portion of the pipe 310 where the cursor 320 is located. Of course, the virtual plane may be displayed in the same manner even when a cylindrical duct is arranged instead of the cylindrical pipe.

  In addition, the side part and upper part or lower part of the piping 310 may be defined as follows. That is, in the cross section orthogonal to the pipe 310, the first and second upper reference lines 314a and 314b extending from the center in a state inclined 60 ° upward from the horizontal plane 313, and the center extending in a state inclined 60 ° downward from the horizontal plane. First and second lower reference lines 315a and 315b are provided (FIG. 4A). The first upper reference line 314a and the first lower reference line 315a are inclined toward one side, and the second upper reference line 314b and the second lower reference line 315b are directed toward the other side. Tilted.

  On the outer peripheral surface of the pipe 310, an arc portion having a central angle of 60 ° between the first and second upper reference lines 314a and 314b corresponds to the upper part of the pipe 310. Further, on the outer peripheral surface of the pipe 310, an arc portion having a central angle of 60 ° between the first and second lower reference lines 315a and 315b corresponds to the lower part of the pipe 310. Further, on the outer peripheral surface of the pipe 310, an arc portion having a central angle of 120 ° between the first upper reference line 314a and the first lower reference line 315a corresponds to a side portion of the pipe 310. Similarly, on the outer peripheral surface of the pipe 310, an arc portion having a central angle of 120 ° between the second upper reference line 314b and the second lower reference line 315b corresponds to the side portion of the pipe 310.

Of course, the angle of the reference line is not limited to this, and can be set to various angles.
Using the route virtual planes 350 and 351 displayed on the design screens 300 and 301, the route of the pipe 310 can be designated in the same manner.

  In addition, on the design screens 100 to 107, 200, 300, and 301 described above, a virtual plane extending horizontally or vertically is displayed. However, the orientation of the virtual plane is not limited to this. When the path object placement plane is not horizontal or vertical, a virtual plane having an inclination with respect to the horizontal direction or the vertical direction is displayed.

  The design screen 303 shows that the additional section 316 is added to the end of the L-shaped pipe 310 described above (FIG. 4B). The additional section 316 is inclined upward by X ° (0 <X <90) with respect to the horizontal direction. In other words, the additional section 316 is arranged on an arrangement surface inclined by X ° with respect to the horizontal direction. When a display operation is performed in a state where the cursor 320 is positioned in the display area on the side of the additional section 316, a route virtual plane 353 that is parallel to the arrangement plane of the additional section 316 and passes through the center line of the additional section 316 is displayed. Is displayed.

  In addition, when a display operation is performed in a state where the cursor is positioned on a joint portion of a route object such as the duct 110 or the pipe 310, the route virtual plane is displayed in the same manner. The joint portion is a portion that connects N (N is an integer of 2 or more) straight sections (connected sections) in the path object. In displaying the route virtual plane, the joint portion is divided into N portions corresponding to the N connected sections. Each part includes a connection part to a corresponding connected section. Further, the joint portion may be divided so that each portion has the same size.

  When a display operation is performed in a state where the cursor is positioned in the display area of each part, a route virtual plane is displayed in the same manner as when the cursor is positioned in the connected section corresponding to the part. That is, when a display operation is performed in a state where the cursor is positioned at each part (side, upper, lower) of the part, it is assumed that the cursor is positioned at the same part in the connected section corresponding to the part, A route virtual plane is displayed.

  To give a specific example, there are two L-shaped joint portions that connect two A and B connected sections extending in different directions: an A portion connected to the A connected section and a B portion connected to the B connected section. It is divided into. The A portion is associated with the A connected section, and the B portion is associated with the B connected section.

  In addition, for example, a T-shaped joint portion that connects two D and E connected sections extending in the same direction and an F connected section extending in a direction different from the D and E connected sections is a D connected section. It is divided into three parts: a connected D part, an E part connected to the E connected section, and an F part connected to the F connected section. The D portion is associated with the D connected section, the E portion is associated with the E connected section, and the F portion is associated with the F connected section.

  In addition, as shown in the design screen 400, when a display operation is performed in a state where the cursor 420 is positioned in the display area of a planar object such as the character 410, a virtual plane 450 along the plane on which the character 410 is arranged. Is displayed (FIG. 4C). Of course, when a display operation is performed in a state where the cursor position is in the display area of another plane object, the virtual plane is displayed in the same manner.

In addition to this, when a display operation is performed in a state where the cursor is located in the display area of the device object, a virtual plane is displayed at the position of the arrangement surface on which the device object is arranged.
Specifically, for example, as shown in the design screen 500, when a display operation is performed in a state where the cursor 520 is positioned in the display area of the toilet 510 that is a device object, the position of the arrangement surface (floor surface) of the toilet 510 The virtual plane 550 is displayed on the screen (FIG. 4D).

  For example, as shown in the design screen 501, when a display operation is performed in a state where the cursor 520 is positioned in the display area of the air conditioner 530 that is a device object arranged on the ceiling, the arrangement surface (ceiling) of the air conditioner 530 is displayed. ) Is displayed at the position (FIG. 5A).

  In addition, a device object that can be arranged along a floor and a wall and has a plurality of arrangement surfaces is assumed. When the cursor is positioned in such a device object display area, a virtual plane corresponding to the arrangement plane corresponding to the cursor position is displayed. Specifically, for example, the virtual plane is displayed on the arrangement plane where the portion where the cursor is located in the device object is arranged, or on the arrangement plane where the portion close to the cursor position is arranged.

  That is, as shown in the design screen 502, it is assumed that the display operation is performed in a state where the cursor 520 is positioned on the side surface of the air conditioner 540 that is a device object that can be arranged along the floor and the wall. In such a case, a virtual plane 570 is displayed at the position of the wall surface in contact with the side surface on which the cursor 520 is positioned (FIG. 5B). Further, it is assumed that a display operation is performed in a state where the cursor 520 is positioned near the bottom of the air conditioner 540 as indicated by the design screen 503. In such a case, a virtual plane 580 is displayed at the position of the floor surface (FIG. 5C).

  In addition, when a display operation is performed in the above-described manner with a virtual plane displayed, a plurality of virtual planes can be displayed on the design screen. On the design screen 108, a virtual plane 157 along the arrangement surface of the L-shaped duct 110 and a virtual plane 158 adjacent to the end portion 113 of the short portion 111 and orthogonal to the direction of the short portion 111 are displayed. (FIG. 5D).

  When two or more virtual planes are displayed, the design support program may accept designation of positions on the intersection line of these virtual planes with a cursor, for example, and perform processing according to the designated positions. Further, for example, the design support program may select a virtual plane being displayed according to an instruction from the user, and perform routing or the like using the selected virtual plane.

(3) Input Acceptance Processing Next, input acceptance processing will be described in which a virtual plane is displayed on the design screen displayed on the display 10 and various inputs are accepted via the virtual plane or the like (FIG. 6). This process is started in response to an instruction from the user.

  In S100, the design support program determines whether or not to accept input for drawing or the like via the design screen. Specifically, the determination may be performed based on an operation received from the user. If the determination is affirmative (S100: Yes), the process ends. If the determination is negative (S100: No), the process proceeds to S105.

  In S105, the design support program determines whether or not a virtual plane is being displayed on the design screen. If the determination is affirmative (S105: Yes), the determination is S110. If the determination is negative (S105: No), S115. Migrate to

  In S110, the design support program determines whether to reset the virtual plane. Specifically, for example, the user may be inquired whether or not to reset the virtual plane and determine whether or not to reset according to an instruction from the user. And when resetting (S110: Yes), it transfers to S115, and when not performing (S110: No), it transfers to S120.

In S115, the design support program displays the virtual plane on the design screen in the above-described manner by executing the virtual plane display process, and proceeds to S120.
In S120, the design support program determines whether or not a virtual plane is displayed on the design screen. If the determination is affirmative (S120: Yes), the process proceeds to S125. If the determination is negative (S120: No), the process proceeds to S100. To do.

In S125, the design support program displays the virtual plane adjustment icon on the design screen in the manner described above, and proceeds to S130.
In S130, the design support program determines whether or not a predetermined operation such as mouse click or dragging has been performed. If the determination is affirmative (S130: Yes), the determination is S135. If the determination is negative, (S130: No). ) Move to S130 again.

  In S135, the design support program determines whether or not the cursor position is in the display area of the virtual plane. If the determination is affirmative (S135: Yes), the determination is S140. If the determination is negative (S135: No), the process proceeds to S130. Transition.

  In S140, the design support program determines the content of the accepted operation. If an operation on the virtual plane (for example, an operation such as clicking or dragging on the virtual plane) is performed, the process proceeds to S145, and an operation on the adjustment icon (for example, clicking on the adjustment icon) is performed. The process proceeds to S155.

  In S145, the design support program specifies the position on the virtual plane in the design drawing corresponding to the cursor position, specifies the three-dimensional coordinates of the position in the design drawing, and draws the design drawing based on the three-dimensional coordinates. Performs processing for drawing, etc. Specifically, for example, as described above, the route object may be routed on the virtual plane based on the specified three-dimensional coordinates. Note that routing may be performed on a virtual plane by the method described in Japanese Patent No. 3242653. In addition to this, elements of a design drawing (for example, various devices and dimension lines) other than the path object may be arranged on the virtual plane based on the specified three-dimensional coordinates. You may move this component currently arranged.

  In subsequent S150, the design support program determines whether or not to continue the operation via the design screen. Specifically, the determination may be performed based on an operation received from the user. If the determination is affirmative (S150: Yes), the process proceeds to S100. If the determination is negative (S150: No), the process ends.

  On the other hand, in S155, which is shifted to when the operation on the adjustment icon is performed in S140, the design support program determines a virtual surface adjustment method. Specifically, if a tilt adjustment icon is clicked, the process proceeds to S160, and if a parallel movement icon is clicked, the process proceeds to S165.

In S160, the design support program adjusts the inclination of the virtual plane by the method described above, and proceeds to S125.
On the other hand, in S165, the design support program adjusts the position by translating the virtual plane by the method described above, and proceeds to S125.

(4) Virtual Plane Display Process Next, a virtual plane display process for displaying a virtual plane on the design screen will be described (FIG. 7). This process is executed from the input reception process.

In S200, the mouse cursor is moved in accordance with an operation from the user.
In subsequent S205, the design support program determines whether or not the cursor position is in the object display area. Specifically, for example, it may be determined whether or not the cursor position exists in any one display area of a route object, an overlay display, a planar object, and a device object. Further, for example, it may be determined whether or not the cursor position is present in the display area of some types (in other words, at least one type) of these four types of objects. If the determination is affirmative (S205: Yes), the process proceeds to S215. If the determination is negative (S205: No), the process proceeds to S200.

  In S215, the design support program determines whether or not there is a virtual plane generation process (generation logic) corresponding to the type of object (target object) present at the cursor position. If the generation logic is present (S220: Yes), the process proceeds to S225. If not (S220: No), the process proceeds to S200.

  In S225, the design support program calculates the position of the virtual plane displayed according to the type of the target object and the position of the cursor in the display area of the target object by the generation logic of the virtual plane in the manner described above. , The process proceeds to S230.

In S230, the design support program displays a virtual plane icon along the calculated display position of the virtual plane, and proceeds to S235.
In S235, the design support program determines whether or not the cursor has moved. If the determination is affirmative (S235: Yes), the process proceeds to S200. If the determination is negative (S235: No), the process proceeds to S240.

  In S240, the design support program determines whether or not a virtual plane display operation has been performed. If the determination is affirmative (S240: Yes), the process proceeds to S245. If the determination is negative (S240: No), the process proceeds to S235. .

  In S245, the design support program determines whether or not a virtual plane is displayed on the design screen. If the determination is affirmative (S245: Yes), the determination is S250. If the determination is negative (S245: No), the process proceeds to S260. Transition.

  In S250, the design support program determines whether or not to additionally display a virtual plane on the design screen based on an instruction from the user. If the determination is affirmative (S250: Yes), the process proceeds to S260. If the determination is negative (S250: No), the process proceeds to S255.

In S255, the design support program deletes the virtual plane displayed on the design screen, and proceeds to S260.
In S260, the design support program displays a virtual plane at the position calculated in S225 on the design screen, and ends this process.

(5) About drawing standard In S145 of the input reception process, when routing is performed on the route virtual plane, a new section (new section) extending from the end of the route object on the route virtual plane is the end, It is arranged at a position corresponding to the drawing standard set corresponding to the route virtual plane. Hereinafter, the drawing standard will be described.

  The drawing reference is provided corresponding to the route virtual plane and the end of the route object located on the route virtual plane. The drawing standard is selected from a plurality of drawing standard candidates arranged at the end along the route virtual plane. Then, when routing is performed on the virtual route plane and a new section extending from the end portion is arranged, the position corresponding to the drawing reference at the tip of the new section follows the mouse cursor.

  FIG. 8A shows a prismatic duct 600, an xy virtual plane 620 that is a path virtual plane parallel to the xy plane, and an xz virtual plane 630 that is a path virtual plane parallel to the xz plane. As an example, the xy virtual plane 620 and the xz virtual plane 630 are respectively arranged at positions that pass through the center of the duct 600.

  When routing is performed on the xy imaginary plane 620 and a new section extending from the opening 610 located on one end side of the duct 600 is arranged, the design support program executes A1 to A3 in the opening 610 according to an instruction from the user. Any one of the drawing reference candidates 611 to 613 is selected as a drawing reference (corresponding to an example of a setting means in claims). The A1 to A3 drawing reference candidates 611 to 613 are arranged along the xy virtual plane 620. On the other hand, when routing is performed on the xz virtual plane 630 and a new section extending from the opening 610 is arranged, the design support program performs B1 to B3 drawing reference candidates 614 to 616 in the opening 610 according to instructions from the user. Is selected as a drawing reference (corresponding to an example of a setting means for claims). The B1 to B3 drawing reference candidates 614 to 616 are arranged along the xz virtual plane 630. In addition, the user may directly specify the position that is the drawing reference in the opening 610.

  When routing is performed on the xy virtual plane 620 and the new section is positioned, the position of the tip of the new section corresponding to the drawing standard selected from the A1 to A3 drawing standard candidates 611 to 613 is displayed on the mouse cursor. Following the movement, the shape of the new section changes according to the position of the tip (FIG. 8B). 9A to 9C show design screens when the duct 600 is viewed in the z-axis direction (in other words, the duct 600 is viewed in a state of facing the xy virtual plane 620).

  First, it is assumed that the A2 drawing reference candidate 612 is the drawing reference (FIG. 9A). In this case, the center 651 at the tip of the new section 650 moves following the mouse cursor 660. Here, when the orientation of the new section 650 is different from the orientation of the original duct 600, the end of the new section 650 is connected to one end of the duct 600, and the angle between the new section 650 and the duct 600 (new section angle). ) Is provided with a joint 652 having a shape. At this time, the original duct 600 is shortened according to the shape of the joint 652, and the position of the opening 610 moves to the other end side. In addition, 640 in FIG. 9 is an auxiliary line indicating the position of the opening 610 of the duct 600 and is not actually displayed on the design screen.

  Next, it is assumed that the A1 drawing reference candidate 611 is the drawing reference (FIG. 9B). In this case, the upper end 653 (portion connected to the upper side surface of the duct 600 in the drawing) at the tip of the new section 650 moves following the mouse cursor 660. On the other hand, it is assumed that the A3 drawing reference candidate 613 is the drawing reference (FIG. 9C). In this case, the lower end 654 (portion connected to the lower side surface of the duct 600 in the drawing) at the tip of the new section 650 moves following the mouse cursor 660.

  Even when the A1, A3 drawing reference 611, 613 is the drawing reference, if the new section angle is larger than 0 °, the joint 652 is arranged at the end of the new section 650 in the same manner. The duct 600 is shortened according to the shape of the joint 652.

  Note that when a new section is routed on the xz virtual plane 630, the new section is similarly arranged according to the drawing standard selected from the B1 to B3 drawing standard candidates 614 to 616. Further, not only the prismatic duct 600 but also other path objects such as a cylindrical duct and a pipe are similarly routed based on the drawing standard.

[effect]
According to the design support program of this embodiment, the cursor position of the mouse on the display area of the virtual plane is specified as the position on the virtual plane in the three-dimensional design drawing. As a result, the components of the design drawing (for example, various devices and dimension lines) on the virtual plane and the routing of the route object are performed, and the design drawing can be created easily and accurately.

  The virtual plane is displayed at a position corresponding to the cursor position. That is, when a display operation is performed by moving the cursor to the display area of the route object, a virtual plane is displayed at a position suitable for routing of the route object. Further, when a display operation is performed by moving the cursor to the display area of the overlay display, a virtual plane is displayed at a position corresponding to the overlay display. Further, when a display operation is performed by moving the cursor to the display area of the planar object, a virtual plane corresponding to the plane on which the planar object is drawn is displayed. Further, when a display operation is performed by moving the cursor to the display area of the device object, a virtual plane is displayed at the position of the device object placement surface. For this reason, the virtual plane is displayed at a position desired by the user by a simple operation.

Therefore, the work can be efficiently performed using the virtual plane.
