The control section 4 is composed of a CPU, has a wall judgment selection section 7 and a pillar judgment selection section 8, and has the storage section 1 described above.
Control the input unit 2 and the output unit 3. Here, the wall determination / selection unit 7 inputs the wall selection precondition information input to the input unit 2 (coordinate information of a surrounding line of a room for drawing a wall, attribute information indicating whether a particular room is a Japanese-style room or a Western-style room, and A wall to be drawn is determined on the basis of attribute information indicating whether the periphery of this particular room is a Japanese-style room / Western-style room or the outside), and drawing information of the wall to be drawn from the wall information storage unit 5 Is output to the output unit 3.

The drawing information of the pillar to be drawn is selected from the pillar information storage unit 6 and output to the output unit 3.

Hereinafter, the operation of the wall and the pillar in this embodiment will be described. Table 1 shows definitions of terms used in the description of this operation. This operation is roughly divided into an operation drawing operation of a wall and an operation drawing operation of a pillar. First, the operation operation of the wall operation drawing will be described. FIG. 2 is a flow chart of a wall automatic operation, which is divided into a design condition setting step, a room attribute setting step, and a wall automatic drawing step. Here, the design condition setting step and the room attribute setting step are steps for inputting various kinds of prerequisite information that are prerequisites for wall drawing, and the wall automatic drawing step is a step for performing automatic drawing of a wall based on the preliminary information. is there.

[0011]

[Table 1]

First, in the design condition setting step, the type of wall to be drawn is registered for each of the walls drawn as a large wall, a single true wall, and a double true wall in the wall automatic drawing step. This type of registration is performed by inputting a preset wall type number, which facilitates registration. If the type is not registered, the operation proceeds according to the preset type. Next, in the room attribute setting step, the room enclosure (room border) is input. This room enclosure is input so that the room enclosures do not intersect with each other and the room enclosure does not include other room enclosures. Then, the attribute of the room (classification of Japanese-style room / Western-style room) is set for each of the rooms indicated by the input room box. If the room attribute is not set in this step, the operation proceeds according to the preset attribute. In the present embodiment, these room enclosures and the attributes of each room are the wall selection prerequisite information.

FIG. 3 is a flow chart of the wall automatic drawing process. First, the room surrounding data (coordinate information of each room) input in the above-mentioned room attribute setting step is read, and this data is sorted in the left-handed order (basically, the left-handed part is registered). Next, the coordinates of the start and end points of the line segment of the enclosing line of each room are read from the room enclosing data, and the wall list data shown in FIG. 11 is created based on each of the read line segments. In the wall list data, the attribute of the room to which the line segment belongs is registered as the left attribute in addition to the start point / end point coordinates of the read line segment, and the line segment belongs to the line segment across this line segment. The attribute of the room facing the room is registered as the right attribute.

After the wall list data is created in this way, a duplication determination is made between this wall list data and the already registered wall list data. That is, the coordinates of each wall list data are compared, and if there are overlapping coordinates, the registered wall list data is divided into an overlapping part and a part other than the overlapping part, and the wall list of the overlapping part is divided. The data is updated with new data. On the other hand, the wall list data created this time is also divided into overlapping and non-overlapping parts,
The part other than the duplication is registered.

After the wall list data having no overlapping part for all the room enclosing lines is registered based on the above flow, the wall data shown in FIG. 12 is created based on the wall list data, and the wall data is created. The wall to be drawn is identified based on the data. That is, the type of wall to be drawn is determined as shown in Table 2 from the left and right attributes of the wall list data shown in FIG. 11, and the wall data of FIG. 12 is determined from this type of wall and the wall coordinates of the wall list data. Is created.

[0016]

[Table 2]

For example, when "Japanese room" is registered in the left / right attributes of the wall list data, "Ryokan" is specified as the type of wall, "Japanese room" is in the left attribute, and "Western room" is in the right attribute. If is registered, “Kata true wall” is specified as the type of wall. On the contrary, the left attribute is "Western-style room".
If "Japanese-style room" is registered in the right attribute, "Katamabe" in the opposite direction (reverse the starting and ending points of the wall to draw)
Is specified. In this way, the wall determination and selection section 7 creates wall data including the type of wall based on the wall selection prerequisite information, and the wall to be drawn is selected from the wall information storage section 5 based on this wall data. Then, the operation is displayed on the output unit 3 and the wall automatic drawing operation is completed. As described above, since the wall determination / selection unit 7 for determining and selecting the wall to be drawn based on the wall selection precondition information is provided, the required wall is automatically drawn only by inputting a small amount of information such as the attribute of the room. You can
Drawing work becomes very easy.

Next, the operation of the automatic drawing of the column will be described.
As shown in FIG. 4, this operation is divided into a design condition setting step, a wall input step, a tube column automatic drawing step, a column input correcting step, and a stud automatic drawing step. Here, the design condition setting process and the wall input process are processes for inputting various prerequisite information that is the premise of the column drawing, and the pipe column automatic drawing process is each of the end points of the wall, the intersection points of the walls and the end points of the fittings. This is the process of drawing a pipe pillar, a character pillar, a half pillar, or a character half pillar. In addition, the column input correction process is for correcting the already input pipe columns, etc.
It is a process of manually inputting the accessory through columns, and the stud automatic drawing process is a process of drawing the studs / single-wall studs or double-wall studs between the entered columns.

First, in the process of setting the design conditions, in the column auto-drawing process and the stud auto-drawing process, as the pillars of pillars, pipe pillars, studs, single true wall studs, double true wall studs, half pillars, half pillars of accessory The type of pillar to be drawn is registered for each pillar to be drawn. This type of registration is supposed to be performed by inputting a preset column type number, which facilitates registration. If the type is not registered, the operation proceeds according to the preset type.

Next, in the wall input step, the coordinates of the end points and the intersections of the walls that generate the columns are input via the input unit 2. In this embodiment, the coordinates of the end points and the intersection points of these walls are the pillar selection prerequisite information. It is not always necessary to manually input this column selection prerequisite information, and this process is linked to the above wall automatic drawing process, and the wall drawing information determined to be drawn in the wall automatic drawing process is the pillar selection prerequisite. Input as information, and based on this pillar selection premise information, the pillar judgment selecting unit 8
May determine the pillar to be drawn. In this case, the drawing information of the wall drawn in the automatic drawing process of the wall is automatically input as the prerequisite information for the column selection in this process, and the labor of inputting the information can be saved. In addition, since it is not necessary to input the type of wall, there is no error in the input work, and the correct architectural drawing can be surely created.

After the column selection prerequisite information is input in this way, the process proceeds to the tube column automatic drawing process. FIG. 5 shows the flow of this process. First, in this step, wall division data is created. FIG. 6 shows a flow of creating wall division data. That is, the information input through the input unit 2,
Alternatively, the drawing information of the wall that is determined to be drawn by the wall determination and selection unit 7 in the wall automatic drawing process is read by the pillar determination and selection unit 8 and then the data of the fittings (type and coordinates) drawn on the drawing are read. ) Is read, and it is determined whether or not this fitting is on the wall.

If there is a fitting on the wall, the information of this fitting is temporarily saved, and the direction of the saved fitting on the wall is unified (the start point and the end point of the fitting are in the same direction as the starting point and the end point of the wall). Align the end points). Moreover, after unifying the directions of the fittings, when a plurality of fittings are present on the same wall, the fittings are sorted in the order of being closer to the starting point of the wall. In this case, when the fittings overlap, the overlapping fittings are merged into one fitting. Through a series of operations from the reading of the fitting data to the arrangement of the overlapping fittings, the coordinates of the fittings to be arranged on the wall on which the pillar is drawn are arranged and specified.

Next, the wall data is divided by the fitting information to create wall division data, and the coordinates at which the pillar is to be drawn and its type are specified. The contents of this wall division data are configured as shown in FIG. That is, the coordinates of the starting point and the ending point of the wall obtained by dividing the wall data as described above, the type of the wall input in the wall input step described above, and the starting point column type (drawing at the starting point of the divided wall Column type to be used) ・ Starting point column angle (angle of column to be drawn at the starting point of the divided wall) ・ Ending column type (Type of column to be drawn at the ending point of the divided wall)
-Ending column angle (angle of the column to be drawn at the end point of the divided wall) is included. Of the wall division data, the starting point column type, the starting point column angle, the ending point column type, and the ending point column angle are specified as shown in Table 3. For example, if the wall type is a large wall and the place to draw is determined to be the end point of the wall by the coordinates of the start point and the end point of the wall, the column type is specified as the tube column and the column angle is Identified as the same angle as the wall.

[0024]

[Table 3]

Here, when the place to be drawn is the end point of the fitting, and when the end point of the fitting does not coincide with the end point or the intersection of the wall, the width of the fitting is compared with the preset reference pitch. Then, the type and angle of the pillar to be drawn are specified by the magnitude relation between the width and the pitch. For example, if the type of wall is a large wall and it is determined that the place to draw is the start point of the fitting and not the end point or intersection of the wall based on the coordinates of the start and end points of the wall, the width of this fitting and the standard pitch If the width of this fitting is less than the reference pitch, the type of pillar is specified as a half pillar, and the angle of the pillar is specified as the same angle as the wall.

After the wall division data is created in this way,
The wall intersection is calculated. FIG. 7 shows the calculation flow of the wall intersection. First, the wall division data is read, and it is determined whether or not the coordinates of the start point and the end point of this wall division data are the same.
When the start point and the end point have the same coordinates, the next wall division data is read while retaining these coordinates, and the wall division data including the wall division data having the same coordinates is searched. When the included coordinate data is searched, the pillar point data of the intersection is created and registered, and when the included coordinate data is not searched, the starting point pillar of the wall division data is registered as the pillar point data.

In the above judgment of whether the start point and the end point are the same, if they are not the same, the start point pillar and the end point pillar of the wall division data are registered as pillar point data. Then, the intersection of the walls is calculated based on the registered wall division data and the next read wall division data. When there is no intersection, the next wall division data is read, the intersection is calculated again, and when there is an intersection, pillar point data of the intersection is created and registered.
At the time of registering each pillar point data described above, if there are pillars already registered at the same point, the kind and angle of the pillar are reviewed and specified based on the strength relationship of the pillars shown in Table 4. For example, when the existing pillar is a tube pillar and the new pillar is a character pillar, the character pillar is drawn at the angle of the character pillar. In this way, the pillar point data is created and registered. FIG. 14 is an example of the pillar point data, which includes coordinates for arranging the pillar, the type of the pillar, the angle of the pillar, and the address of the next data.

[0028]

[Table 4]

Some special processing is performed in the above-mentioned creation / registration of a series of pillar point data.
As one of the special processing, first, the space between the columns to be drawn is 1
If the space is exceeded, columns will be assigned for each space according to the type of wall. That is, in the process of creating the wall division data described above, when it is determined that the distance between the pillars to be drawn exceeds one space, the pillars are drawn every space. The types of columns to be drawn in this way are to draw a tube column for a large wall and a character column for a single true wall and a double true wall.

Here, when one side end is an end other than the fitting (a start point and an end point of the wall, an intersection of the walls) among the intervals of the pillars exceeding 1 interval, the pillar is generated based on the end other than the fitting. If the pillars are drawn one by one, 100
It is said that no column will be generated in the extra space when the extra space is less than mm. In addition, the reference point for drawing in the case of drawing for each interval is the end point other than this fitting when only one fitting is input, and in other cases, from left to right / bottom on the screen Plotted in the order from top to bottom. By performing the special processing in this way, it is possible to automatically draw pillars other than the end points and intersections of the walls, and the pillar drawing work becomes easy.

As the next special treatment, R wall (wall other than straight line)
And the other wall (including the R wall), or the pillar points where the distance between the pillar points is less than 100 mm are ignored, and the pillars are not drawn. Among these, the operation of ignoring pillar points of less than 100 mm is performed based on a fixed priority order. For example, the distance between the end point of the wall and the end point of the fitting is 100.
If it is less than mm, the end points of the fittings are disregarded with priority, similarly, the intersections of the walls are disregarded with priority over the end points of the fittings, and similarly, the pillar points that are drawn for each interval have priority over the intersections of the walls. Is ignored. Also, when fittings and fittings overlap,
Do not draw on the end points of joiners placed in other joiners. By performing the special processing in this way, the columns are not drawn below a certain interval, and unnecessary columns are not drawn.

In the case where a sliding door or a sliding door is used as the fitting as another special treatment, if the pillar is located at the retracting portion of these fittings, the pillar will not interfere with the pulling operation of the door. Is moved. For example, in the sliding door shown in FIG. 5, when the pillar point is located in the retracting part of the fitting (post-processing pillar point 2 in the figure), this pillar point is processed as a pillar point that has moved by the reference value. (Post-processed pillar point 2 in the figure).

Here, the reference value is l- (P1 + P2) +1.
It is a value calculated as 00 mm (P1 and P2 are clearance widths of fittings). Further, the special processing is similarly performed in the case of using the sliding door or the sliding door shown in FIG. 6, and the reference point in this case is a value calculated as (1− (P1 + P2) +100) / 2 mm. By performing the special treatment in this manner, the pillar can be appropriately drawn even when a special fitting such as a sliding door is used, and the drawing work of the pillar becomes easy.

After the pillar point data is created and registered through such special processing, the pillar data is created based on this pillar point data. FIG. 8 shows a pillar data creation flow. First, the pillar point data is read, converted to pillar data, and written to a file, and then the second point coordinates (paired with the pillar arrangement coordinates indicating the center position of the pillar) based on the pillar angle of this pillar point data. The angle of the column is specified by the position of this coordinate with respect to the column arrangement coordinate) and is similarly written in the file to create the column data. In this way, the pillar determination and selection unit 8 creates pillar data based on the pillar selection premise information, and the pillar to be plotted is selected from the pillar information storage unit 6 based on the pillar data, and the output unit 3 is displayed and the automatic drawing process of the pipe column ends.

In the next column input correction step, the column automatically created in the above-mentioned automatic drawing step of the tube column, the input of the column to be newly drawn, and the input of the through column and the accessory column to be newly input are performed. The operation is performed via the input unit 2, and then the stud automatic drawing process is started. In this stud automatic creation process, there is a wall between the already input pipe pillar, character pillar, half pillar, half pillar, half pillar, and half pillar, and where there is no fitting, the stud and stanchion ( Katsuma wall stanchions on both sides and both true walls on both sides are drawn at a constant drawing pitch.

In the case of the studs, the drawing pitch is an interval (0.1 mm unit) obtained by dividing the preset reference pitch by the preset number of stud divisions and rounding. For example, if the reference pitch is 500 mm and the stud division number is 3, the drawing pitch is 167 mm. Similarly, the drawing pitch of single-wall studs is the standard pitch divided by the number of uni-wall studs and rounded off, and the drawing pitch of both true-wall studs is the standard pitch divided by the number of true-wall studs. . However, in all cases, when the distance between the last column and the column to be calculated is 100 mm or less, the last column is not drawn.

FIG. 9 is a flow chart of the stud auto-drawing process. First, in this step, wall division data is created. The creation of this wall division data is the same as the above-mentioned tube column automatic operation diagram, and details thereof will be omitted. Next, the stud data creation process is performed. FIG. 10 is a stud data generation flow chart. First, the wall division data and the pillar data are read, and it is determined whether the pillar is on the wall division data. Then, the pillar information is saved, and the saved pillar information is sorted based on the coordinates.

The pitch between the sorted pillar information is judged, and if the pitch is not less than the drawing pitch + 101 mm, studs and studs are drawn. Also, the angle of the studs and studs to be drawn here is the same as the angle of the wall. In this way, the stud determination / selection unit 8 determines and selects the studs to be drawn, and the studs are displayed on the output unit 3 to complete the stud automatic drawing process. As described above, the column determination and selection unit 8 for determining and selecting the columns to be drawn based on the column selection precondition information is provided, so that the required columns are automatically selected by inputting a small amount of information such as the type of wall and coordinate information. The drawing can be done dynamically, and the drawing work becomes very easy.

[0039]

As described above, according to the present invention, the storage unit, the input unit, the output unit and the control unit are provided, and the storage unit has the wall information storage unit for storing the drawing information of the wall, and the control unit is the input unit. It has a wall judgment and selection unit that judges the wall to be drawn based on the input wall selection premise information and selects the drawing information of the wall to be drawn from the wall information storage unit and outputs it to the output unit. The required wall can be automatically drawn by simply inputting a small amount of information such as attributes, and this has the effect of facilitating drawing creation work.

Further, according to the present invention, the storage unit has a pillar information storage unit, and the control unit determines the pillar to be drawn based on the pillar selection precondition information input to the input unit and draws from the pillar information storage unit. If you have a column judgment selection section that selects drawing information of a power column and outputs it to the output section, you can automatically draw the required column by inputting only a small amount of information such as the type of wall. This has the effect of significantly reducing the time and effort required for creation.

Further, according to the present invention, when the pillar judgment selecting unit of the control unit judges the pillar to be drawn based on the attribute information of the wall to be drawn which is judged by the wall judgment selecting unit, Since the columns can be automatically drawn based on the drawn wall and there is no need to input the type of the wall, there is an effect that the work of creating the column drawing becomes easier.

Further, according to the present invention, when the pillar judgment selecting unit judges the pillar to be drawn based on the attribute information of the wall to be drawn which is judged by the wall judgment selecting unit, the type of wall etc. Since there is no need to input, there is an effect that there is no error in the input work and a correct architectural drawing can be created with certainty.
