  The input interface 4a receives an input signal from the input device 2 and outputs it to the CPU 4c. The output interface 4 b receives an image signal from the CPU 4 c and outputs it to the display device 3.

  The ROM 4d stores a program such as BIOS. The internal storage device 4f is, for example, an HDD or the like, and stores an operating system program and application programs. The CPU 4c implements various functions by executing programs stored in the ROM 4d and the internal storage device 4f while using the RAM 4e as a work area.

  The external storage device 5 is a server or the like, and is connected to the control device 4 via a network such as a LAN. The external storage device 5 stores a two-dimensional (2D) drawing of the product. The two-dimensional (2D) drawing of the product may be stored in the internal storage device 4f. Further, the external storage device 5 may be installed at a location away from the control device 4.

  FIG. 2 is a diagram showing functional blocks of the drawing creation support apparatus 1 according to the present embodiment. As shown in FIG. 2, the drawing creation support apparatus according to the present embodiment includes a dimension line generation unit 41a, a dimension line automatic arrangement unit 41b, a projection drawing view arrangement unit 41c, and a view position interference cancellation unit 41d. It is out. Each of these functional blocks is realized by the CPU 4c (see FIG. 1) executing a program stored in the internal storage device 4f.

  The dimension line generation unit 41a generates a dimension line based on the figure on the drawing. The dimension line automatic arrangement unit 41b refers to the dimension line initial position database (DB) 51a stored in the external storage device 5, and arranges the dimension line generated by the dimension line generation unit 41a on the drawing. The dimension line initial position database (DB) 51a will be described later in detail.

The projected view is a general term for a front view, a side view, and a plan view. The projection view initial position database (DB) 51b will be described in detail later.

  The view position interference canceling unit 41 d refers to the projection-by-frame projection view initial position database (DB) 51 c stored in the external storage device 5 and cancels the interference in the projection view. The projected frame view initial position database (DB) 51c for each frame will be described in detail later.

  The initial dimension position database (DB) 51a, the projected view initial position database (DB) 51b, and the projected frame view initial position database (DB) 51c for each frame may be stored in the internal storage device 4f.

  FIG. 3 is a flowchart showing a procedure of dimension line generation processing of the drawing creation support apparatus 1 when creating a two-dimensional drawing from a three-dimensional drawing. In step S12, the dimension line generation unit 41a (see FIG. 2) of the drawing creation support apparatus 1 reads the position information of the reference line on the figure outline of the two-dimensional (2D) drawing of the product in response to the user's specification. Note that the two-dimensional drawing has coordinate information. FIGS. 4A and 4B are diagrams each showing a part of a figure outline of a two-dimensional (2D) drawing of the product. The user operates the input device 2 (see FIG. 1) to specify a reference line on the figure outline of the two-dimensional (2D) drawing of the product, and the dimension line generation unit 41a displays the position information of the specified reference line. Read.

  Referring to FIG. 3 again, the dimension line generation unit 41a starts reading the position information of the end points on the figure outline in step S14. Specifically, the dimension line generation unit 41a identifies the end point of the figure from the outline of the figure using the reference line as the start line. The end point is an inflection point of the outline of the figure. Next, the dimension line generation unit 41a reads the position information of the end point X (N) (N is a natural number with an initial value of 1) as step S16, and reads the position information of the end point X (N + 1) as step S18. Next, the dimension line generation unit 41a compares the distance from the reference line of the end point X (N) with the distance from the reference line of the end point X (N + 1) as step S20. Referring to FIG. 4A, there are three end points X (1) to X (3), and the distances from the reference line 101 at each end point are different. On the other hand, referring to FIG. 4B, there are three end points X (1) to X (3), and the distance from the reference line 111 of the end point X (1) and the end point X (2) The distance from the reference line 111 coincides. In the case of the example illustrated in FIG. 4B, the dimension of the two end points X (1) and X (2) can be indicated by one dimension line 112.

  Referring to FIG. 3 again, in step S22, the dimension line generation unit 41a compares the distance from the reference line of the end point X (N) with the distance from the reference line of the end point X (N + 1) for all end points. It is determined whether or not. If the dimension line generation unit 41a determines that the distance from the reference line of the end point X (N) to the distance from the reference line of the end point X (N + 1) is not compared for all end points (No), N is determined. Increment, and the process proceeds to step S16. On the other hand, when the dimension line generation unit 41a determines that the distance from the reference line of the end point X (N) to the distance from the reference line of the end point X (N + 1) is determined for all end points (Yes), the process is performed. Proceed to step S24.

  If the dimension line generation unit 41a determines in step S22 that the distance from the reference line of the end point X (N) to the distance from the reference line of the end point X (N + 1) has been compared for all end points (Yes), step S24 is performed. As above, the position information of the end point X (N) (N is a natural number with an initial value of 1) is read. Next, the dimension line generation part 41a acquires the information required for dimension line generation from a CAD system as step S26. Information necessary for generating the dimension line is information held as CAD data such as an auxiliary line length and a numerical font size.

  Next, in step S28, the dimension line generation unit 41a generates (draws) a dimension line from the reference line to the end point X (N) based on the information acquired in step S26, and draws the dimension value. When the dimension line from the reference line to the end point X (N) is generated, the dimension line generation unit 41a sets an internal flag related to the end point X (N) and uses it for subsequent determinations.

  Next, the dimension line production | generation part 41a determines whether the dimension line was produced | generated about all the end points as step S30. The dimension line generation unit 41a can determine whether or not a dimension line has been generated for all end points depending on whether or not the internal flag is set for all end points. If it is determined that no dimension line has been generated for all end points (No), the dimension line generation unit 41a increments N and advances the process to step S24. If the dimension line generator 41a determines that dimension lines have been generated for all end points (Yes), the process ends. FIG. 5 is a diagram showing an example in which dimension lines are generated for all end points of a figure. The shorter each dimension line, the closer to the figure outline, that is, the closer to the reference line. In FIG. 5, the dimension lines 122, 123, 124, 125, 126 and 127 are arranged in this order from the side closer to the reference line 121. At this time, each dimension line is provisionally arranged, and the distance between each dimension line is a provisional distance and has not yet been determined.

  FIG. 6 is a flowchart showing a procedure of the dimension line automatic arrangement processing of the drawing creation support apparatus 1. In step S32, the dimension line automatic arrangement unit 41b (see FIG. 2) of the drawing creation support apparatus 1 determines the dimension line length of the end point X (1) (the shortest dimension line among all dimension lines (hereinafter, the shortest dimension line). Read the length). Next, the dimension line automatic arrangement unit 41b reads the dimension line initial position database 51a as step S34. FIG. 7 is a diagram illustrating an example of the dimension line initial position database 51a. The dimension line initial position database 51a is a database that defines the distance at which the shortest dimension line is arranged from the end of the reference line on the figure outline in association with the length of the shortest dimension line. For example, when the shortest dimension line length is 3 mm or less, the position at which the shortest dimension line is arranged is 5 mm from the end of the reference line on the figure outline. For example, when the shortest dimension line length exceeds 3 mm and is 6 mm or less, the position at which the shortest dimension line is arranged is 7 mm from the end of the reference line on the figure outline.

  Referring to FIG. 6 again, the dimension line automatic arrangement unit 41b determines and arranges the display position of the shortest dimension line in step S36. Referring to the example of the dimension line initial position database 51a shown in FIG. 7, the dimension line automatic arrangement unit 41b, for example, sets the shortest dimension line as the reference line on the figure outline when the shortest dimension line length is 3 mm or less. It arrange | positions in the position of 5 mm from an edge part. Referring to FIG. 4A, for example, when the length of the shortest dimension line 102 is 3 mm or less, the shortest dimension line 102 is disposed at a position 5 mm from the end of the reference line 101. For example, when the length of the shortest dimension line 102 exceeds 3 mm and is 6 mm or less, the shortest dimension line 102 is disposed at a position 7 mm from the end of the reference line 101.

  Referring to FIG. 6 again, the dimension line automatic arrangement unit 41b reads the initial value of the distance between dimension lines from the external storage device 5 in step S38. FIG. 8 is a diagram illustrating an example of a distance between dimension lines. As shown in FIG. 8, the initial value of the distance between the dimension lines is determined by the size (height) + P (predetermined value) of a numeric font representing the dimension value. For example, when the font size (height) is 7 mm and P is 3 mm, the initial distance between the dimension lines is 10 mm.

  Referring to FIG. 6 again, the dimension line automatic arrangement unit 41b arranges dimension lines other than the shortest dimension line in step S40. FIG. 9 is a diagram illustrating an example in which dimension lines are arranged. As shown in FIG. 9, the shortest dimension line 132 is arranged at a position based on the dimension line initial position database 51a from the reference line 131 on the figure outline. The dimension lines 133, 134, and 135 other than the shortest dimension line 132 are arranged such that the distance between the dimension lines is the initial value of the distance between the dimension lines (= font size + P).

  The drawing creation support apparatus 1 repeatedly executes the processes shown in FIGS. 3 and 6 until the necessary projection view (front view, top view, side view, etc.) has been created.

  Note that the drawing is provided with a figure frame that is a rectangle serving as a reference for arranging a projected view, a parts table, and the like. The picture frame corresponds to the size of the drawing paper. When the size of the drawing paper is changed, the size of the picture frame is also changed according to the size of the drawing paper. In the present embodiment, the coordinate origin of the picture frame is the lower left corner. FIG. 10 is a diagram illustrating an example of the picture frame coordinates. As shown in FIG. 10, the coordinate origin of the picture frame 60 is the lower left corner. The lower right area 60a of the picture frame 60 is an area in which a part name and a drawing number are entered, and the upper right area 60b of the picture frame 60 is an area in which a parts table that is a list of component parts is entered. It is.

  FIG. 11 is a flowchart showing the procedure of the projection view arrangement process of the drawing creation support apparatus 1 and the process of eliminating the interference between the projection view and the figure frame line. The drawing creation support apparatus 1 starts the processing shown in FIG. 11 with the initial drawing size (paper size for printing the drawing) as A4 (JIS P 0138). The processing target drawing is assumed to be a “component A type” drawing.

  The projection view arrangement unit 41c (see FIG. 2) of the drawing creation support apparatus 1 reads the projection view initial position database 51b in step S42. FIG. 12 is a diagram illustrating an example of the projection view initial position database 51b. As shown in FIG. 12, the projected view initial position database 51b is a database that defines coordinates for arranging each projected view (front view, side view, plan view) for each component type. This coordinate is a coordinate based on the origin of the picture frame, and is a coordinate where the lower left corner of the projection view (front view, side view, plan view) is arranged. Here, since the processing target drawing is a drawing of “part A type”, the projection view arrangement unit 41c has coordinates (15, 15) for arranging the front view, coordinates (60, 15) for arranging the side view, The coordinates (15, 60) for arranging the plan view are read.

  Next, the projection view arrangement unit 41c arranges a front view at a position of a1 from the left side of the frame and b1 from the upper side of the region 60a as step S44. Here, since the coordinates for arranging the front view are (15, 15), a1 = 15 and b1 = 15− (the height of the region 60a). FIG. 13 is a diagram showing an example of the drawing in which the front view 61 is arranged in the picture frame 60.

  Next, the projection view arrangement unit 41c arranges a side view at a2 from the right end of the front view in step S46. Here, since the coordinates for arranging the side view are (60, 15), a2 = 60− (width of the front view) −a1. FIG. 13 is a diagram showing an example of the drawing in which the side view 62 is arranged in the picture frame 60.

  Next, the projection view arrangement unit 41c arranges a plan view at a position b2 from the upper end of the front view in step S48. Here, since the coordinates for arranging the plan view are (15, 60), b2 = 60− (height of the front view) −b1− (height of the region 60a). FIG. 13 is a diagram showing an example of a drawing in which a plan view is arranged in a picture frame 60.

  Next, the view position interference cancellation unit 41d (see FIG. 2) determines whether or not the projected view views 61, 62, and 63 interfere with the picture frame 60 in step S50. Specifically, referring to FIG. 13, the view position interference canceling unit 41d has a distance between the upper end of the plan view 63 and the upper end of the picture frame 60 that is equal to or greater than a predetermined value b3 (see FIG. 13) and the right end of the side view 62. Is the predetermined value a3 (see FIG. 13) or more, and the distance between the upper end of the side view 62 and the lower end of the region 60b where the parts table is entered is the predetermined value b5 (FIG. 13). Reference) It is determined whether or not the above condition is satisfied.

  If the view position interference cancellation unit 41d determines that the above condition is not satisfied in step S50 (No), that is, if it determines that the projection view 61, 62, 63 and the drawing frame 60 interfere with each other, the view position interference drawing 41d is performed as step S52. By increasing the size of the paper by one size and enlarging the picture frame accordingly, the interference between the projected view views 61, 62, 63 and the picture frame 60 is eliminated. At this time, the view position interference cancellation unit 41d refers to the figure-by-frame projection view initial position database 51c, and acquires the projection map arrangement coordinates corresponding to the new picture frame. FIG. 14 is a diagram illustrating an example of the projected frame view initial position database 51c for each frame. The figure-by-frame projection view initial position database 51c is a database that defines the position where the projection view is arranged in association with the size of the drawing sheet. Referring to FIG. 14, when the drawing size of “part A type” is enlarged to A3, the coordinates for arranging the front view are (30, 30). Thereafter, the view position interference cancellation unit 41d advances the process to step S44, and again arranges the projected view.

  On the other hand, if the view position interference canceling unit 41d determines in step S50 that the above condition is satisfied (Yes), that is, if it is determined that the projected view and the drawing frame do not interfere with each other, the process ends.

  In the above process, when the above condition is not satisfied (when the projection view and the picture frame interfere), the drawing is enlarged by one size to eliminate the interference between the projection view and the picture frame. However, it is also possible to reduce the projection view (front view, side view, and plan view) by reducing the font size of the numbers representing the dimensions, thereby eliminating the interference between the projection view and the picture frame. FIGS. 15A and 15B are diagrams illustrating an example of a projected view. By reducing the font size and shortening the intervals between the dimension lines 142, 143, and 144 in the projection view shown in FIG. 15A, the projection view can be reduced as shown in FIG. 16A and 16B are diagrams illustrating examples of the drawings. As shown in FIG. 16B, when the side view 62 and the plan view 63 protrude from the picture frame 60 as shown in FIG. The side view 62 and the plan view 63 can be accommodated in the picture frame 60.

  As described above, in the present embodiment, the end line of the figure designated by the user is read as the reference line, the reference line is used as the start line, the end point of the figure is identified from the outline of the figure, and the distance between the end point and the reference line The length of the dimension line indicating is determined, and the dimension line is drawn based on the determined length of the dimension line. This eliminates the need to manually specify the outline of the figure on the drawing.

  Also, based on a dimension line initial position database that defines the position of the shortest dimension line, the shortest dimension line is arranged, and based on the initial distance between the dimension lines determined according to the size of the numeric font representing the dimension value. Thus, the dimension lines other than the shortest dimension line are arranged so that the distance between the dimension lines becomes the initial value of the distance between the dimension lines. This eliminates the need to manually adjust the dimensional position.

  In addition, based on the projection view initial position database that defines the placement position of the projection view, the projection view is placed in a coordinate system with one corner of the view as the origin, and there is interference between the view and the view. In this case, the interference between the projected view and the picture frame is eliminated by enlarging the drawing size. Accordingly, it is possible to eliminate the necessity of arranging each projection view in the figure frame in consideration of the dimensional arrangement in the view.

  In addition, based on the projection view initial position database that defines the placement position of the projection view, the projection view is placed in a coordinate system with one corner of the view as the origin, and there is interference between the view and the view. In such a case, the size of the numeric font representing the dimension value is reduced and the size of the projection view is reduced, thereby eliminating the interference between the projection view and the picture frame. Accordingly, it is possible to eliminate the necessity of arranging each projection view in the figure frame in consideration of the dimensional arrangement in the view.

  As described above, the drawing creation support apparatus according to the present invention is useful for supporting the creation of drawings.
