<Layer command execution processing>
FIG. 22 shows a flowchart of the layer command execution process (# 5 in FIG. 5) of the system 1. The layer command execution process executes the layer command (FIGS. 3A to 3F) and displays the two-dimensional object (circle object 21, polyline object of FIG. 20) displayed by the three-dimensional CAD software 8. 22, 3D solid 30 (headed stud solid 31, cylindrical solid 32, surface material solid 33, wire material solid 34, L-shaped steel solid 35, tube solid 36) by layer command is superimposed on line segment object 23). It is a process to display.

  In the layer command execution process, first, the computer 5 reads the two-dimensional object (two-dimensional figure) depicted in the two-dimensional figure 20 displayed by the three-dimensional CAD software 8 from the three-dimensional CAD software 8 (# 21 ). That is, when the user selects a range on the two-dimensional diagram 20 by operating the mouse 3, the computer 5 reads all the two-dimensional objects drawn in the selected range from the three-dimensional CAD software 8. Include. In other words, the computer 5 sets the data (layer name, type, two-dimensional position, diameter, length) of all the two-dimensional objects drawn in the selected range. Data such as height, shape, size, direction, etc.) is acquired from the three-dimensional CAD software.

  At this time, regarding the data of each two-dimensional object acquired from the three-dimensional CAD software 8, the computer 5 sets the data of the kth (k = 1, 2,...) Two-dimensional object as object data Ak. That is, if the number of two-dimensional objects read from the three-dimensional CAD software 8 is n, the first two-dimensional object data is the object data A1, the second two-dimensional object data is the object data. A2..., The last two-dimensional object data is defined as object data An. Therefore, the object data Ak is the layer name and type of the k-th two-dimensional object read from the three-dimensional CAD software 8, the two-dimensional position on the two-dimensional figure 20, the diameter, the length, the shape, the size, and the direction. Etc. are included.

  Further, the computer 5 reads the layer command from the spreadsheet software 9 (# 22). That is, the computer 5 receives data input to the data input table 51 for stud commands, data input to the data input table 52 for cylindrical commands, data input to the data input table 53 for face material commands, and wire rods. Data input to the command data input table 54, data input to the shape steel command data input table 55, and data input to the tube command data input table 56 are acquired from the spreadsheet software 9. .

  At this time, the computer 5 sets the data in the kth row (k = 1, 2,...) Throughout the data input tables 51 to 56 as command data Ck. That is, if data is input to a total of m rows in the data input tables 51 to 56, the data in the first row of the data input table 51 is command data C1, and the data in the second row of the data input table 51 is command data. The data of the last line of the data input table 56 for C2,... Therefore, the command data Ck is data input to the kth row throughout the data input tables 51 to 56 (the type of data differs depending on which of the data input tables 51 to 56 is input). Is included.

  Further, the computer 5 determines that the command data Ck is the stud command data, the column command data, the surface material command data, the wire material command data, the shape steel command depending on which of the data input tables 51 to 56 the command data Ck is. Data and tube command data are classified. That is, if it is data of the data input table 51, it will be stud command data, if it is data of the data input table 52, it will be column command data, if it is data of the data input table 53, it will be face material command data, If it is data, it will be wire command data, if it is data in the data input table 55, it will be section steel command data, and if it is data in the data input table 56, it will be tube command data.

  The processes of # 21 and # 22 are processes (first data acquisition process) for acquiring data necessary for displaying the three-dimensional solid by the layer command from the three-dimensional CAD software 8 and the spreadsheet software 9.

  Subsequently, the computer 5 initializes the value i of the first counter to i = 1 (# 23). Here, the value i of the first counter is a value for identifying the object data Ak (k = 1, 2,..., N). That is, processing is performed on object data Ai among object data A1, A2,..., An corresponding to the value i of the first counter. If the value i of the first counter is not i = n + 1 (NO in # 24), the computer 5 initializes the value ii of the second counter to ii = 1 (# 25). Here, the value ii of the second counter is a value for identifying the command data Ck (k = 1, 2,..., M). That is, processing is performed on the command data Cii of the command data C1, C2,..., Cm corresponding to the value ii of the second counter.

  Thereafter, if the value ii of the second counter is not ii = m + 1 (NO in # 26), the computer 5 reads the two-dimensional object corresponding to the object data Ai (i-th read from the three-dimensional CAD software 8). It is determined whether or not the two-dimensional object is a circle object 21 (# 27). This determination is made based on data (data indicating the type of a two-dimensional object) included in the object data Ai.

  If the two-dimensional object corresponding to the object data Ai is the circle object 21 (YES in # 27), the computer 5 determines whether Dii matches Di (# 28). Here, Dii is input to the diameter input field 51b or the diameter input field 52b of the total ii line throughout the data input tables 11 to 16 according to the diameter of the circle object 21 included in the command data Cii. The diameter of the circle object 21 is. Di is the diameter included in the object data Ai, and thus the diameter of the two-dimensional object corresponding to the object data Ai, and the diameter of the i-th two-dimensional object read from the three-dimensional CAD software 8 It is. That is, the computer 5 calculates the diameter of the i-th two-dimensional object read from the three-dimensional CAD software 8 as the diameter of the circle object 21 input in the total ii rows throughout the data input tables 11 to 16. It is determined whether or not it matches. That is, the computer 5 identifies the circle object 21 from the two-dimensional objects depicted in the two-dimensional diagram 20 based on the diameter of the circle object 21, and the command data Cii is associated with the circle object 21. It is judged whether it is a thing.

  If Dii matches Di (YES in # 28), the computer 5 creates a three-dimensional solid 30 based on the command data Cii (# 29). That is, the computer 5 executes a layer command according to the 3D software 10 (using the macro function of the spreadsheet software 9) based on the command data Cii, defines a three-dimensional solid based on the command data Cii, Three-dimensional display data for displaying the solid 30 on the two-dimensional object corresponding to the object data Ai is created, and the three-dimensional solid 30 based on the three-dimensional display data is displayed on the two-dimensional figure 20.

  That is, if the command data Cii is the stud command data, the computer 5 executes the stud command based on the command data Cii, and sets the headed stud solid 31 based on the command data Cii to 2 corresponding to the object data Ai. Three-dimensional display data to be displayed on top of a three-dimensional object (FIG. 3A) is created. That is, based on D1, D2, H1, T1, color data of the headed stud solid 31 included in the command data Cii, and data of the two-dimensional position of the circular object 21 included in the object data Ai, Three-dimensional display data for displaying the headed stud solid 31 having the dimensions D1, D2, H1, and T1 on the two-dimensional position of the circle object 21 is created. However, the three-dimensional display data adjusted based on the Z adjustment (1) value for the stud command and the Z adjustment (2) for the layer command is created.

  If the command data Cii is cylindrical command data, a cylindrical command is executed based on the command data Cii, and the cylindrical solid 32 based on the command data Cii is overlaid on the two-dimensional object corresponding to the object data Ai. Three-dimensional display data for display (FIG. 3B) is created. That is, based on D1, L1, h1, color data of the cylindrical solid 32 included in the command data Cii, and data on the two-dimensional position of the circular object 21 included in the object data Ai, the circular object 21 3D display data for displaying the cylindrical solid 32 of the color D1 and L1 at the height position h1 on the two-dimensional position is created. However, the three-dimensional display data adjusted based on the Z adjustment (1) value for the cylinder command and the Z adjustment (2) for the layer command is created.

  The computer 5 delivers the created three-dimensional display data to the three-dimensional CAD software 8 and displays the three-dimensional solid 30 based on the three-dimensional display data on the two-dimensional figure 20 in an overlapping manner. As a result, the three-dimensional solid 30 (headed stud solid 31 or cylindrical solid 32) based on the command data Cii is displayed on the two-dimensional object (circle object 21) corresponding to the object data Ai. The displayed three-dimensional solid 30 can be used by the three-dimensional CAD software 8. In addition, the computer 5 passes the use and layer name data included in the command data Cii to the three-dimensional CAD software 8 so that the data can be used by the three-dimensional CAD software 8.

  In the process of # 29, using the data acquired from the three-dimensional CAD software 8 and the spreadsheet software 9, the stud command or column command of the layer command is executed, and the headed stud solid 31 or the column solid 32 is displayed in the two-dimensional diagram. This is a process (first three-dimensional solid creation process) for displaying the image on the circle object 21 on 20.

  On the other hand, if the two-dimensional object corresponding to the object data Ai is not the circle object 21 in # 27 (NO in # 27), the computer 5 reads the two-dimensional object (three-dimensional CAD software 8) corresponding to the object data Ai. It is determined whether the i-th two-dimensional object) is the polyline object 22 or the line segment object 23 (# 30). This determination is made based on data (data indicating the type of a two-dimensional object) included in the object data Ai.

  If the two-dimensional object corresponding to the object data Ai is the polyline object 22 or the line segment object 23 (YES in # 30), the computer 5 determines whether Eii matches Ei (# 31). Here, Eii is the layer name of the polyline object 22 or the layer name of the line segment object 23 included in the command data Cii, and accordingly, the 2D layer input field in the total ii rows throughout the data input tables 11-16. The layer name of the polyline object 22 or the layer name of the line segment object 23 input to 53b, 54b, 55b, or 56b. Ei is the layer name included in the object data Ai, and hence the layer name of the two-dimensional object corresponding to the object data Ai. The i-th two-dimensional object read from the three-dimensional CAD software 8 Is the layer name. That is, the computer 5 reads the layer name of the polyline object 22 or the layer name of the line segment object 23 input from the three-dimensional CAD software 8 in the total ii rows throughout the data input tables 11 to 16. It is determined whether or not it matches the layer name of the i-th two-dimensional object. That is, the computer 5 identifies the polyline object 22 or the line segment object 23 from the two-dimensional objects depicted in the two-dimensional diagram 20 by the layer name of the polyline object 22 or the layer name of the line segment object 23. Then, it is determined whether or not the command data Cii is associated with the polyline object 22 or the line segment object 23.

  If Eii matches Ei (YES in # 31), the computer 5 creates a three-dimensional solid 30 based on the command data Cii (# 32). That is, the computer 5 executes a layer command according to the 3D software 10 (using the macro function of the spreadsheet software 9) based on the command data Cii, and defines the three-dimensional solid 30 based on the command data Cii. Three-dimensional display data for displaying the three-dimensional solid 30 on the two-dimensional object corresponding to the object data Ai is created, and the three-dimensional solid 30 based on the three-dimensional display data is displayed on the two-dimensional figure 20. .

  That is, if the command data Cii is the face material command data, the computer 5 executes the face material command based on the command data Cii, and the face material solid 33 based on the command data Cii corresponds to the object data Ai. Three-dimensional display data to be displayed on top of the two-dimensional object (FIG. 3C) is created. That is, the two-dimensional position, length, shape, size, direction, and the like of the T1 and h1 of the face material solid 33 included in the command data Cii, the color data, and the polyline object 22 included in the object data Ai. On the basis of the data, the surface material solid 33 of the color T1 having the same shape and size of the bottom surface as the polyline object 22 is displayed at the height position h1 on the two-dimensional position of the polyline object 22. 3D display data is created. However, the 3D display data adjusted based on the Z adjustment (1) value for the face material command and the Z adjustment (2) for the layer command is created.

  If the command data Cii is wire command data, the wire command is executed based on the command data Cii, and the wire solid 34 based on the command data Cii is overlaid on the two-dimensional object corresponding to the object data Ai. Three-dimensional display data for display (FIG. 3D) is created. That is, T1, B1, h1, color data of the wire solid 34 included in the command data Cii, and data such as the two-dimensional position, length, and direction of the line segment object 23 included in the object data Ai. Based on the two-dimensional position height height h1 of the line segment object 23, the direction and length are the same as those of the line segment object 23, and the line solid object 34 of the color T1 and B1 is displayed. Create three-dimensional display data. However, three-dimensional display data adjusted based on the wire command Z adjustment (1) value and the layer command Z adjustment (2) is created.

  If the command data Cii is shape data command data, the shape data command is executed based on the command data Cii, and the L-shape solid 35 based on the command data Cii is converted into a two-dimensional object corresponding to the object data Ai. Three-dimensional display data to be displayed on top of each other (FIG. 3E) is created. That is, the deviation, B, t, h1, color data included in the command data Cii, the two-dimensional position, length, and direction of the line segment object 23 included in the object data Ai. Based on such data, the direction and length of the line segment object 23 are the same as the line segment object 23 at the height position h1 on the position laterally shifted from the two-dimensional position of the line segment object 23, and the dimensions B and t thereof. Three-dimensional display data for displaying the color L-shaped steel solid 35 is created. However, the three-dimensional display data adjusted based on the Z adjustment (1) value for the shape steel command and the Z adjustment (2) for the layer command is created.

  If the command data Cii is tube command data, the tube command is executed based on the command data Cii, and the tube solid 36 based on the command data Cii is overlaid on the two-dimensional object corresponding to the object data Ai. Three-dimensional display data for display (FIG. 3F) is created. That is, the D, h1, and color data of the tube solid 36 included in the command data Cii, and the two-dimensional position, length, shape, and size of the line segment object 23 or polyline object 22 included in the object data Ai. Based on the data such as the direction, the direction and length are the same as the line segment object 23 or the polyline object 22 at the height position h1 on the two-dimensional position of the line segment object 23 or the polyline object 22 and the dimensions. Three-dimensional display data for displaying the tube solid 36 of that color of D is created. However, the three-dimensional display data adjusted based on the tube command Z adjustment (1) value and the layer command Z adjustment (2) is created.

  The computer 5 delivers the created three-dimensional display data to the three-dimensional CAD software 8 and displays the three-dimensional solid 30 based on the three-dimensional display data on the two-dimensional figure 20 in an overlapping manner. As a result, on the two-dimensional object (polyline object 22 or line segment object 23) corresponding to the object data Ai, the three-dimensional solid 30 (surface material solid 33, wire material solid 34, L-shaped steel solid 35, based on the command data Cii, Or the tube solid 36) is displayed. The displayed three-dimensional solid 30 can be used by the three-dimensional CAD software 8. Further, the computer 5 transfers the use and layer name data (including the angle data if the command data Cii is tube command data) included in the command data Cii to the three-dimensional CAD software 8, and The data is made available to the 3D CAD software 8.

  In the process of # 32, a surface material command, a wire material command, a shape steel command, or a tube command of the layer command is executed using the data acquired from the three-dimensional CAD software 8 and the spreadsheet software 9, and the surface material solid 33 is obtained. The wire solid 34, the L-shaped steel solid 35, or the tube solid 36 is displayed on the polyline object 22 or the wire solid 34 on the two-dimensional figure 20 (first three-dimensional solid creation processing).

  After creating the 3D solid 30 at # 29 and after creating the 3D solid at # 32, the computer 5 increments the value ii of the second counter by 1 (# 33), and after # 26 Repeat the process. In addition, when Dii does not match Di at # 28 (NO at # 28) and when Eii does not match Ei at # 31 (NO at # 31), the computer 5 determines the value ii of the second counter. Is incremented by 1 (# 33), and the processes after # 26 are repeated. Also, when the two-dimensional object corresponding to the object data Ai is not the polyline object 22 or the line segment object 23 in # 30 (NO in # 30), the computer 5 increases the value ii of the second counter by 1. (# 33), the process from # 26 is repeated. By repeating the processes of # 26 to # 33, it is sequentially determined whether or not the command data C1, C2,..., Cm are associated with one object data Ak. If it is attached, a layer command based on the command data is executed, and the three-dimensional solid 30 based on the command data is displayed superimposed on the two-dimensional object corresponding to the object data Ak. When a plurality of command data among the command data C1, C2,..., Cm includes the same layer name, a plurality of three-dimensional solids 30 by the plurality of command data have the layer names It is displayed superimposed on one two-dimensional object corresponding to the included object data Ak.

  When the value ii of the second counter becomes ii = m + 1 at # 26 (YES at # 26), it means that the processing has been completed for all of the command data C1, C2,..., Cm. The value i of the first counter is increased by 1 (# 34), and the processes after # 24 are repeated. Is the command data C1, C2,..., Cm associated with each of the object data A1, A2,..., An by repeating the processes of # 24 to # 34? If they are determined in order and associated with each other, a layer command based on the command data is executed, and the three-dimensional solid 30 based on the command data is overlaid on the two-dimensional object corresponding to the object data.

<3D tube command execution processing>
FIG. 23 is a flowchart of the solid tube command execution process (# 11 in FIG. 5) of the system 1. In the 3D tube command execution process, the 3D tube command (FIG. 4) is executed, and a 3D solid 30 (3D tube solid 37) is generated by the 3D tube command on the 2D diagram 20 displayed by the 3D CAD software 8. This is a process of displaying them in an overlapping manner.

  In the three-dimensional tube command execution process, first, the computer 5 reads the three-dimensional tube command from the spreadsheet software 9 (# 41). That is, the computer 5 sets the data in the k-th row (k = 1, 2,...) Of the data input table 71 for the solid tube command as the command data Ck. That is, if data is input to a total of n rows in the data input table 71, the data in the first row of the data input table 71 is command data C1, the data in the second row is command data C2,. The data on the line is command data Cn. Therefore, the command data Ck includes data input in the k-th row of the data input table 71.

  Subsequently, the computer 5 initializes the value i of the first counter to i = 1 (# 42). Here, the value i of the first counter is a value for identifying the command data Ck (k = 1, 2,..., N). That is, processing is performed on the command data Ci among the command data C1, C2,..., Cn corresponding to the value i of the first counter. If the value i of the first counter is not i = n + 1 (NO in # 43), the computer 5 initializes the value ii of the second counter to ii = 1 (# 44). Here, the value ii of the second counter counts the number of times the mouse 3 is clicked (instructed) on the two-dimensional diagram 20 (the break point Pk (k = 1, 2,... Of the solid tube solid 37). This is a value for identifying). That is, corresponding to the value ii of the second counter, the iith click by the operation of the mouse 3 is targeted (of the folding points Pii among the folding points P1, P2,..., Pm). ) Is processing.

  Thereafter, the computer 5 determines whether or not the value ii of the second counter is ii = m + 1 (# 45). Here, m is the number of clicks included in the three-dimensional tube command Ci, that is, the number of clicks input to the click number input field 71f of the i-th row of the data input table 71 (of the break point Pk of the three-dimensional tube solid 37). Number m). If the value ii of the second counter is not ii = m + 1 (NO in # 45), the computer 5 is the X coordinate value Xii at the position clicked (instructed) by the operation of the mouse 3 on the two-dimensional diagram 20. The Y coordinate value Yii is acquired from the three-dimensional CAD software 8 (# 46). That is, when the computer 5 is clicked on the two-dimensional diagram 20 by the operation of the mouse 3, the computer 5 sets the two-dimensional position (X coordinate value and Y coordinate value) of the clicked position on the two-dimensional diagram 20 to 3. It is acquired from the dimensional CAD software 8, and the X coordinate value of the two-dimensional position is set to Xii, and the Y coordinate value of the two-dimensional position is set to Yii.

  Further, the computer 5 acquires the Zii coordinate value corresponding to the click from the spreadsheet software 9 (# 47). That is, the computer 5 includes the ii-th height position Zii included in the three-dimensional tube command Ci, that is, the height position Zii (ii = 1) input in the Zii input field of the i-th row of the data input table 71. In the case of the height position Z1 input in the Z1 input field 71g, in the case of ii = 2, the height position Z2 input in the Z2 input field 71h,..., In the case of ii = 10, in the Z10 input field 71p. The input height position Z10) is acquired from the spreadsheet software 9.

  Here, the computer 5 corresponds the X coordinate value Xii and Y coordinate value Yii of the two-dimensional position acquired from the three-dimensional CAD software 8 in # 46 and the height position Zii acquired from the spreadsheet software 9 in # 47. In addition, one three-dimensional position Uii (Xii, Yii, Zii) is defined. The three-dimensional position Uii (Xii, Yii, Zii) is set as the three-dimensional position of the break point Pii of the three-dimensional tube solid 37.

  Thereafter, the computer 5 increments the value ii of the second counter by 1 (# 48), and repeats the processing after # 45. As a result, the computer 5 repeats the processes of # 46 and # 47 each time it is clicked on the two-dimensional figure 20 by the operation of the mouse 3, and a plurality of three-dimensional positions U1 (X1, Y1, Z1), U2 ( X2, Y2, Z2),..., Um (Xm, Ym, Zm) are defined. These three-dimensional positions Uk (Xk, Yk, Zk) (k = 1, 2,..., M) are set as the three-dimensional positions of the break points Pk. That is, U1 (X1, Y1, Z1) is the three-dimensional position of the break point P1, U2 (X2, Y2, Z2) is the three-dimensional position of the break point P2, ..., Um (Xm, Ym, Zm) The three-dimensional position of the point Pm is assumed. That is, the computer 5 sets the position clicked k-th time on the two-dimensional diagram 20 by the operation of the mouse 3 as the two-dimensional position Sk (Xk, Yk) of the k-th break point Pk, and k in the data input table 71 Height input in the first Zk input field (Z1 input field 71g when k = 1, Z2 input field 71h when k = 2,..., Z10 input field 71p when k = 10) The position is set as the height position Zk of the k-th folding point Pk.

  When the value ii of the second counter becomes ii = m + 1 in # 45 (YES in # 45), processing is completed for all of the first click, second click,..., M-th click. The computer 5 acquires the curvature R, thickness (diameter) D, and color data included in the command data Ci from the spreadsheet software 9 (# 49). The processes of # 45 to # 49 are processes (second data acquisition process) for acquiring data necessary for displaying the solid tube solid 37 by the solid tube command from the three-dimensional CAD software 8 and the spreadsheet software 9. .

  The computer 5 uses a plurality of three-dimensional positions Uk (Xk, Yk, Zk) (k = 1, 2,..., M) defined by repetition of the processes of # 46 and # 47, and the curvature acquired at # 49. A three-dimensional solid 30 is created based on R, thickness D, and color data (# 50). That is, the computer 5 executes a solid tube command according to the 3D software 10 (using the macro function of the spreadsheet software 9) based on these data, defines a solid tube solid 37 based on these data, Three-dimensional display data for displaying the tube solid 37 superimposed on the two-dimensional figure 20 (FIG. 4) is created, and the three-dimensional tube solid 37 based on the three-dimensional display data is displayed on the two-dimensional figure 20.

  That is, in the computer 5, each three-dimensional position Uk (Xk, Yk, Zk) is a break point Pk, and between each break point Pk (between each three-dimensional position Uk) is a straight line. Three-dimensional display data is generated for displaying a solid tube solid 37 of that color, the portion of which is a thickness D and each bending point Pk is a curved surface having a curvature R, superimposed on the two-dimensional figure 20. However, the three-dimensional display data adjusted based on the three-dimensional tube command Z adjustment (1) value and the three-dimensional tube command Z adjustment (2) are created. The computer 5 delivers the created three-dimensional display data to the three-dimensional CAD software 8 and displays the three-dimensional tube solid 37 based on the three-dimensional display data on the two-dimensional figure 20 in an overlapping manner. Thereby, the solid tube solid 37 based on the command data Ci is displayed on the two-dimensional diagram 20. The displayed three-dimensional solid can be used by the three-dimensional CAD software 8. In addition, the computer 5 passes the data of the use and layer name included in the command data Ci to the three-dimensional CAD software 8 and makes the data usable by the three-dimensional CAD software 8. The process of # 50 is a process of displaying a 3D tube solid 37 superimposed on the 2D FIG. 20 by executing a 3D tube command using data acquired from the 3D CAD software 8 and the spreadsheet software 9 (No. 1). 2 three-dimensional solid creation process).

  After creating the three-dimensional solid 30 in # 51, the computer 5 increments the value i of the first counter by 1 (# 51), and repeats the processing after # 43. By repeating the processes of # 43 to # 51, the three-dimensional tube commands based on the command data C1, C2,... The solid 37 is displayed so as to be superimposed on the two-dimensional figure 20. When the value i of the first counter becomes i = n + 1 in # 43 (NO in # 43), it means that the processing has been completed for all of the command data C1, C2,..., Cn. Completion display is performed (# 52), and the solid tube command execution process is terminated.

  According to such a system 1, data is input to the data input tables 51 to 56 (and the Z adjustment (2) input field 57), the execution button 58 is clicked by operating the mouse 3, and the two-dimensional diagram By selecting the range on 20 by operating the mouse 3, the data is input to the data input tables 51 to 56 on the two-dimensional objects (circle object 21, polyline object 22, line segment object 23) in the selected range. A three-dimensional solid 30 (headed stud solid 31, cylindrical solid 32, face material solid 33, wire material solid 34, L-shaped steel solid 35, tube solid 36) based on the data is displayed in an overlapping manner.

  In addition, data is input to the data input table 71 (and the Z adjustment (2) input field 72), the execution button 73 is clicked by the operation of the mouse 3, and the top of the two-dimensional diagram 20 is clicked by the operation of the mouse 3.
