Abstract

PURPOSE:To constitute a housing CAD system capable of corresponding to the addition of a member or the change of member information and to enable a user to customize the member formed as parametric parts by forming the member as the parametric parts. CONSTITUTION:The housing CAD system is provided with a registering means 3, a storage means 2, a processing means 1, and designing means 1, 4, and the registering means 3 registers a member element formed in the system as parts and the storage means 2 stores the three-dimensional information of the registered parts and the processing means 1 converts data into an optional size in accordance with the three-dimensional information of the stored parts, and the designing means 1, 4 use the parts formed by processing to design a house. Thus, the member can be easily changed by forming the internally formed member as parts and maintaining the member formed as parts.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a single-family house design CAD in the field of architecture, and particularly to a method for generating member information.

(Prior Art) Conventionally, in this type of CAD system, members such as curtain boards, long presses, round greens, and tatami mats have been generated within the system.

(Problems to be Solved by the Invention) In the conventional housing CAD system described above, members such as curtain boards, long presses, surrounding edges, and tatami mats are not compiled into a library as parts, but are generated internally within the system. For this reason, there are disadvantages in that it cannot handle changes in the shape or size of each member, and cannot handle new types of members.

K, which makes this compatible, requires modification of the system (internal processing of the program) and has the disadvantage of short system life.

An object of the present invention is to provide a housing CAD system that eliminates the above-mentioned drawbacks by converting internally generated parts into parts, maintaining the parts, and making it possible to easily change parts. There is a particular one.

(Means for solving the l! problem) A housing CAD system according to the present invention is configured to include a registration means, a storage means, a processing means, and a design means.

The registration means is for registering the member elements generated within the system as parts.

The storage means is for storing three-dimensional information of registered parts.

The processing means is for converting the data into arbitrary dimensions according to the stored three-dimensional information of the nine parts.

The design tool is for designing houses using parts made in the process.

(Implementation row) Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a residential CAD system according to the present invention.

Housing CAD using 3D parametric parts for housing
The system is roughly divided into four parts.

In Figure 1, 1 is the housing CAD department! 3 is a parts database maintenance section, 4 is a housing database, 5 is a parts identification section, and 6 is a parametric parts placement section.

The housing CAD section 1 has a conventional housing CAD function and a parts identification section 5.
This is a CAD part that supports housing design. Parts database! is a database for storing various information on parametric parts and regular parts (fittings, fixtures, etc.), and is referenced by the housing CAD section 1. Parts Database Maintenance Department S is a parts database! The user uses the component database maintenance section 3 to create or modify component information interactively while viewing various information about the component on the CRT screen. When defining a parametric component in the component database maintenance section 3, various types of parametric information must be specified.

Parametric information consists of direction information and position information regarding fixed parts and free parts (parts determined by the placed position) of the part. For example, in the case of tatami, two axes (thickness of tatami) are shown in Figure 2.
is fixed, and the x-axis and y-axis directions (the size of the tatami mat) are determined by the size of the room in which it is placed, so they are free parts. In this way, the fixed direction (axis) and
Define the direction (axis) of freedom.

As shown in FIG. 8, for windows and the like, position information of the fixed part/free part is required even in the free direction as well as the fixed/free direction. In other words, the length of the sash-like part is fixed, and the length of the glass part can be changed freely. If there is no position information and only direction information is provided, the window sash frame portion will also become long, as shown in FIG.

The housing database 4 stores information about the designed housing such as walls, pillars, parametric parts, and free parts, all of which are stored in a determined state.

Next, the partial identification section 5 and the parametric component arrangement section B inside the house CAD 1 will be explained.

The component identification unit 5 refers to the component database using the component code (a code assigned in accordance with the model of the component) as a key, and determines whether or not the part is a parametric component. If it is a parametric part, the free part/
Extract information about the direction (axis) and position of the fixed part. The parametric component placement section 6 is a component for arranging a component when the component identification section 6 determines that the component is a parametric component. For example, when editing a plane, that is, when designing a room or house while looking from above, parametric parts can be placed in the x-axis or y-axis direction, and the position of the reference point of the part can be changed as shown in Figure 5. Instruct as shown in ■, display the figure registered at the specified reference point, express the parametric (free) part with a rubber band, and make it follow the cursor as shown in ■ in Figure 5. .

Again, the parametric (free) portion is fixed at the indicated position and information such as length or width is determined and stored in the housing database as shown at 0 in FIG.

Next, the flow of processing according to this embodiment will be explained.

First, a parametric part shape is created using the parts database maintenance system, and the parametric direction and position are determined and stored in the parts database 2.

After creating the necessary parts, start the housing CAD 1 and edit (add/delete/move) walls, columns, general fittings, etc. interactively while looking at the screen. At the same time, parametric parts will also be added. When a parametric component is selected as a component to be additionally placed, a rubber band is displayed in the parametric direction from the first designated position, and the cursor is moved with a shape using the mouse (tablet).

When the second point is specified, the length in the parametric direction is determined at the specified position, and the shape of the figure is also fixed there.

Thereafter, this part will not be deleted or moved, and will be treated as a fixed, upper-shaped part. Pick up the final parts, pick up the quantity of parts used in the designed house, and then add up these to get the determined length or width.

(Effects of the Invention) As explained above, the present invention can create a housing CAD system that can generate members as parametric parts, add members, or change member information, and can create parametric parts. This has the effect of allowing the user to customize the nine components.

Another advantage is that users can handle their own parts (locally procured materials) within CAD.
