The storage device 40 stores plan view information representing a plan view. The plan view information includes graphic information necessary for arranging a figure in a virtual space and character information in a virtual space. And character information necessary for the operation. The graphic information and the character information have coordinate information for specifying the arrangement position of the graphic or the character on the plan view. That is, the graphic is arranged at the arrangement position on the plan view specified by the coordinate information based on the graphic information, and the character is
Based on the character information, it is arranged at the arrangement position on the plan view specified by the coordinate information.

5 is a diagram showing a plan view drawn in an editing area of the display device 50, FIG. 5 is a diagram showing a display screen for requesting input of height information, and FIG. FIG. 4 is a diagram showing a cross-sectional view drawn in FIG.

When editing a plan view, the user specifies, from the input device 30, for example, the plan view information stored in the storage device 40 to be edited. When the plan view information to be edited is designated in the sectional view drawing device 10, the plan view information is read from the storage device 40, and in the editing area of the display device 50, based on the read plan view information. A plan view is created. Specifically, a figure is arranged at a position specified by the coordinate information based on the figure information included in the plan view information, and specified by the coordinate information based on the character information included in the plan view information. By arranging the characters at the positions, a plan view is drawn. Thereafter, in the same manner as a known CAD device, the user can use the input device 30 to arrange a figure or a character in an editing area and edit them.

On the other hand, when drawing a cross-sectional view from a plan view, the user first makes a cut line on the plan view using the input device 30 as shown in FIG. to set the L _c. In this case, chamber name of the plan view ( "work chamber", "a warehouse", etc.) as the cutting line L _c is applied to specify the center left P _s of a plan view as a starting point, the center right edge P _e plan view by specifying the end point, it shall set cutting line L _c. Thus, cross-sectional view taken along a line L _c is drawing.

Next, the user requests a request to execute the information acquisition process from the input device 30 by, for example, selecting an execution command menu for the information acquisition process. In cross-sectional view drawing apparatus 10, when a request for executing the information acquisition process is inputted, in step S104, a plurality of on cutting line L _c a intersection with other lines on the diagram cutting line L _c and flat The distance between the intersections is calculated. In the example of FIG. 4, since the other 16 lines in the drawing the cutting line L _c and the plane intersect,
Intersection points P _s , P _{0 to} P ₁₃ , P between the cutting line _Lc and these lines
The distance of each section of _e is calculated. That is,
Intersection P _s, P ₀ distance, the intersection point P _0, P ₁ distance, the intersection P _1, P ₂ distance, ..., the intersection P _13, P _e distance, so that the distance meter 15 interval is calculated. For example, these distances are "50
0,8400,200,5400,3900,200,4
800 "," 200 "," 4400 "," 200 "," 300 "," 5900 ",
It is calculated as “200”, “6400”, “384”.

Once the distance between the intersections has been calculated,
In step S106, the cutting line L _cNote that depends on
No. etc. are acquired. In the example of FIG.
(X1 to X4), room name ("work room", "warehouse", etc.), line
The color and line type are obtained. Then, in step S108
And the calculated distance between intersections and the acquired symbols, etc.
Is stored in the storage device 40.

Next, although not shown, the user sets a reference line in any one of the editing areas and inputs a request for executing the cross-section drawing process by selecting an execution command menu of the cross-section drawing process. Request from device 30. In the sectional view drawing device 10, when a request to execute the information acquisition process is input, in step S204, a request for inputting height information is sent to the display device 5 through a window screen as shown in FIG.
Displayed as 0. In the display screen of FIG. 5, input requests for "floor height", "top height", "top slab thickness", and "floor height" are displayed as "separation", "number of floors", and height information. Here, as shown in the figure, the user responds to the request on the display screen, for example, “4000” as “away”.
, “1FL” as “floor”, and “40” as “floor height”.
The input device 30 inputs “00”, “2700” as “top height”, “200” as “top slab thickness”, and “0” as “floor height”.

When the height information is input, then, in step S206, the distances and symbols between the intersections stored in the information acquisition processing are read from the storage device 40, and the read distances between the intersections are read. , Symbols, etc., and the input height information, a sectional view is drawn in the editing area as shown in FIG. In FIG. 6, points P ′ _s , P ′ ₀ 〜
The distances of the sections P ′ ₁₃ and P ′ _e are the intersections P _s , P ₀ , the intersections P ₀ , P ₁ , the intersections P ₁ , P ₂ ,. It is determined by P _13, P _e distance. Similarly, the symbols and the like arranged in FIG. 6 are the symbols and the like acquired in the information acquisition process.

As described above, in the present embodiment, the plan view information is read from the storage device 40, a plan view is created based on the read-out plan view information, and when a sectional view is created from the plan view, cutting is performed. calculating a distance between a plurality of intersection points on line L _c and cutting line a intersection with other lines of the plan view L _c, drawing a cross section based on the distance and height information between calculated intersection point I did it.

As a result, even if the plan view is complicated, a sectional view can be easily drawn from the plan view as compared with the related art, so that the design work can be performed efficiently and the plan view can be efficiently performed. And the cross-sectional view can be accurately matched. Further, in the present embodiment, when drawing a sectional view from the plane view is like symbols suffering cutting line L _c (as heart, as heart symbol, chamber name, line color, line type, etc.) to get the A cross-sectional view is created based on the acquired symbols and height information.

As a result, even if the plan view is complicated, necessary information among the information on the plan view can be easily reflected on the cross-sectional view, so that it is not necessary to correct the drawn cross-sectional view. In addition, the design work can be performed more efficiently. Of course, the consistency with the plan view can be further improved. In the above-described embodiment, the case has been described in which a basic sectional view in which the ceiling height is constant is drawn.
However, the present invention is not limited to this, and if more detailed height information such as a floor height, a ceiling height, and a fixture effective height is included in the plan view information, a substantially completed cross-sectional view can be drawn.

Further, in the above-described embodiment, in executing the processing shown in the flowcharts of FIGS. 2 and 3, the case where a program stored in advance in the ROM 14 is executed has been described, but the present invention is not limited to this. Alternatively, the program may be read from a recording medium on which a program indicating these procedures is recorded, loaded into the RAM 16, and executed.

Here, the recording medium is a semiconductor storage medium such as a RAM or a ROM, a magnetic storage type storage medium such as an FD or HD, an optical reading type storage medium such as a CD, CDV, LD, or DVD; It is a magnetic storage type / optical readout type storage medium, and includes any storage medium that can be read by a computer irrespective of an electronic, magnetic, optical or other reading method.
