BACKGROUND OF THE INVENTION
The present invention relates to a CAD system for a unit building that supports design work of a unit building using a computer.
[0002]
[Background]
Conventionally, a unit type building constructed by combining a plurality of box-shaped building units manufactured in a factory at a construction site has been used.
According to such a unit-type building, when manufacturing a building unit at a factory, most of the work conventionally performed at the construction site is performed at the factory, and the work at the construction site is remarkably reduced, and high quality There is an advantage that a building can be constructed in a short period of time.
[0003]
Since such unit-type buildings are designed one by one according to the various demands of customers, as with general custom-built buildings, the efficiency of design work and manufacturing work is ensured sufficiently. It is designed using a CAD system (refer to Japanese Patent Laid-Open No. 8-137930).
Specifically, on the screen of the display device constituting the CAD system, a flat rectangular building unit is input, and a plan view of a unit type building is designed by combining these building units. The contour was entered. According to such a CAD system, a box-shaped building unit can be designed simply by inputting the planar shape and the floor height of the building unit, so that the design work can be performed accurately and quickly.
At this time, since there is no room space in the roof of the roof, when designing the roof of the unit type building, the roof plan was expressed simultaneously on the plan view of the unit type building.
[0004]
[Problems to be solved by the invention]
By the way, in recent years, the roof of a unit type building may be constituted by a substantially horizontal land roof portion and a roof portion formed by a roof such as a dormitory or a gable. A living room space is provided in the back of the roof of the standing roof part, and it is possible to go from this living room space to the flat roof part.
In this case, the method of inputting the outline of the roof in the plan view of the unit type building cannot represent the room space in the attic, so it is necessary to create a roof plan in addition to the plan view. Since the elevation of the shape is triangular or trapezoidal, corresponding to the shape of the roof, it cannot be entered using the same input method as a box-shaped building unit, and the room space in the back of the hut is a pillar. , Input for each part such as beams. Therefore, a great deal of labor and time are required for the roof design work.
[0005]
The objective of this invention is providing the CAD system for unit type buildings which can perform the design work of a roof easily.
[0006]
