DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a CAD network system for creating a house design drawing and a method for creating a house design drawing using the system.

[0002]

2. Description of the Related Art Conventionally, CAD has been used to create design drawings of houses.
The use of (Computer Aided Design) systems is widely practiced. In that case, commercially available general-purpose CA
Since it is inefficient to create a house design drawing using the D program, a CAD program dedicated to creating a house design drawing having a library (database) of various components of the house has been developed. In addition, as a computer that installs such a CAD program for exclusive use of a house and creates a design drawing, a computer called a workstation, which is more expensive and has higher functions than a personal computer, is usually used.

[0003]

By the way, the above-mentioned CAD program for exclusive use of a house cannot create all of the design drawings, but usually makes it possible to create only a plan view (floor plan) of each floor of the house to be built. Therefore, for example, when a front view, a sectional view, and the like are required for a wall portion, a fitting, and the like, these drawings are separately created by hand. Also, at the above workstation, CAD for exclusive use of housing
For example, even when wiring such as a lighting fixture is input in a plan view created using a program, these are added by hand. As described above, since about half of the conventional design drawings are created by handwriting, there is a problem that it takes a considerably long time to create the design drawings as a whole.

[0004] Further, when a design drawing needs to be corrected due to a meeting with a user, if the plan drawing is to be corrected, it is necessary to correct the plan drawing at the above-mentioned workstation, so that the work load on the workstation is increased. However, problems such as a delay in creating a design drawing for another user are likely to occur. In the case of correcting a front view, a cross-sectional view, or the like, it is necessary to correct it by hand, but in that case, there is a problem that a great deal of labor and time are required. Therefore, conventionally, in order to minimize the correction by handwriting after the meeting with the user, at the time of the meeting, a plan view created by the CAD program for exclusive use of the house and a minimum handwritten drawing are presented, and the final After the drawings are determined, the remaining handwritten drawings are created or corrected by handwriting, but in such a case, it takes a long time until the final drawing is completed after a meeting with the user.

[0005]
