Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a CAD system for a unit type building which supports design work of a unit type building using a computer.

[0002]

BACKGROUND ART 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 in a factory, most of the work conventionally performed at the construction site is performed at the factory, the work at the construction site is significantly reduced, and high quality There is an advantage that the building can be built in a short period of time.

In such a unit-type building, as in the case of a general custom-built building, the unit-type buildings are designed one by one in response to the diverse needs of customers, so that the efficiency of design work and manufacturing work can be sufficiently ensured. Is designed by utilizing a CAD system (see Japanese Patent Laid-Open No. 8-137930). Specifically, on the screen of a display device that constitutes a CAD system, a planar rectangular building unit is input, and after combining these building units to design a plan view of a unit-type building, a roof is displayed on this plan view. I was entering the contour. According to such a CAD system, a box-shaped building unit can be designed only by inputting the plane shape and floor height of the building unit, so that the design work can be performed accurately and quickly. At this time, since there is no living space in the attic behind the roof, when designing the roof of the unit-type building, the floor plan of the unit-type building was expressed at the same time.

[0004]

By the way, in recent years, the roof of a unit type building may be composed of a substantially horizontal flat roof portion and a stationary roof portion formed by a roof such as a dormitory or a gable. A living room is provided in the back of the shed on the stationary roof, and you can access the flat roof from this living space. In this case, the method of inputting the outline of the roof to the floor plan of the unit-type building cannot express the living space in the attic, so it is necessary to create a floor plan in addition to the floor plan.
Since the elevation of the living space in the attic is triangular or trapezoidal, which corresponds to the shape of the roof, it cannot be entered using the same input method as for box-shaped building units. I had to enter the living room space for each part such as pillars and beams.
Therefore, a lot of labor and time were required for the roof design work.

It is an object of the present invention to provide a unit type CAD system for buildings, which enables the roof design work to be easily carried out.
