Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building remodeling support device that can be used, for example, when designing a house when remodeling the house.

[0002]

2. Description of the Related Art In recent years, demands for houses have become diverse due to diversification of consumer needs. Therefore, when constructing a new house, it usually takes considerable time and effort not only for designing the frame but also for selecting equipment.

Therefore, using a personal computer CAD, as shown in FIG.
A building CAD integrating device as shown in FIG. 4 has been proposed.
This building CAD accumulating device includes an input device, a display device, various output devices, and a main body device having a CAD device, an accumulating device, an output control device, and an optional device. When a floor plan is input from the input device, Since the CAD device selects fittings and housing-related equipment such as air conditioners, the end user can be convinced to design a house. In addition, the integrating device automatically integrates such as picking up trees, and the output control device causes various output devices to output a printed matter such as an estimate or a three-dimensional perspective drawing.

However, since new construction is difficult due to soaring land prices, the number of home remodeling for refurbishing or expanding existing homes is rapidly increasing. Then, when the house is reformed, the reform plan of the building is created by using only the drawing creation function and the estimate creation function in the building CAD integrating device.

However, the conventional building CAD integrating device has a problem in that it cannot provide sufficient design support for a home remodeling plan.
Specifically, it is impossible to calculate only the remodeling part or set various types of work required for renovation work that is often involved in remodeling. This is because, in the case of a new construction, the settings of various works are collectively made, and it is not necessary to set the cost of only the remodeling part and the settings of various works peculiar to the repair work.

Further, in the conventional building CAD accumulator, there is a problem that it is practically difficult for a non-expert such as a first-class architect to enter the contents of various works and select a work type. .

Further, even in the conventional building CAD accumulator, a default construction pattern may be prepared as a recommended plan, but there is no support for a wide variety of construction works in the case of remodeling.

By the way, regarding the method of presenting the finish of the reform, in the three-dimensional color perspective diagram, the actual finish situation, for example, the sense of depth, existing furniture or furniture under consideration for new purchase and wallpaper after reform It is very difficult to judge whether or not they match each other, and predict whether or not furniture under consideration for new purchase can be dimensionally installed after remodeling. Therefore, a gap in the finished image may occur between the contractor and the user (owner), and this gap may cause a trouble.

As described above, the conventional building CAD accumulator has a problem that it is impossible to plan and present a reform plan efficiently.

In view of the above, an object of the present invention is to provide a building remodeling support device capable of efficiently planning and presenting a remodeling plan.
