Abstract

PURPOSE:To improve the production efficiency of a plane plan by providing a peripheral map data input means, a measuring line calculating means, an oblique line limitation calculation/display register means, an adverse shade calculation/display register means, and a plane plan production means. CONSTITUTION:A site/code data input means 1-4 inputs the site peripheral data on a site form peripheral map, the code conditions, etc., via the two-dimensional plotting. A measuring line calculation/display means 1-5 calculates and displays the shade measuring lines of a site via the means 1-4. An oblique lien calculation/register display means 1-6 calculates a constructable space that clears all regulations based on the calculation of the number of stories, the floor height, etc. An adverse shade calculation/display register means 1-7 calculates a constructable space which clears the shade and oblique line regulations. Then a plane plan production means 1-8 produces a plane plan of each floor based on the site form, the oblique line limitation, and the adverse shade. Thus it is possible to produce a plane plan of each floor while checking the coverage and the floor area ratio which are important factors of the building code.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for creating a planar plan in an architectural CAD system.

[Conventional technology]

In architectural design work, creating a floor plan is the basis for creating architectural drawings, but conventionally, floor plans are created with only site data, legal data, and surrounding maps in mind.

[Problem to be solved by the invention]

The conventional floor plan creation method described above is done only by considering site data, legal data, and surrounding maps, without paying much attention to building coverage ratios and floor area ratios. The problem is that the floor plan may be revised to ensure the consistency of the drawings later, resulting in many design changes.

[Means to solve the problem]

The floor plan creation method of the present invention includes a means for inputting site/legal data, a means for inputting surrounding map data, a means for calculating measurement lines, a means for calculating and displaying diagonal line restrictions, and
A special feature characterized by having a means for calculating and displaying and registering reverse shading, and a means for creating a floor plan while displaying diagonal reverse shading for each floor with consideration to building coverage ratio and floor area ratio [Example] Next Next, the present invention will be explained with reference to the drawings.

〔composition〕

As shown in FIG. 1, the present invention provides site/legal data input means 1-4. Measurement line calculation means 1-5. Diagonal line calculation registration display means 1-6. It is composed of a reverse shadow calculation display registration means 1-7 and a planar plan creation means 1-8.

[Each part/peripheral configuration]

1-10 is a drawing storage device, 1-1 is a graphic display, 1-2 is a keyboard, 1-3 is a tablet, 1
-12 is a floppy disk, and 1-11 is a plotter.

[Function of each means]

Instructions are input using a keyboard 1-2 or a stylus pen on a tablet 1-3.

The site/regulatory data input means 1-4 uses two-dimensional drawing to input the site shape, the surrounding map of the site, the boundary line and direction for a multi-use district, the area name, site area designation, and the use area type (residential area, residential area, etc.). Enter the following information: commercial area, etc.), fire prevention area type (fire prevention, semi-fire prevention area), shade regulation value, legal conditions for altitude area type, and site side data (roads, adjacent land, parks, etc.).

The measurement line calculation display means 1-5 calculates and displays the shade measurement lines of the assumed sites of 5 m and 10 m based on the site shape and site side data inputted by the site/legal data input means 1-4.

The diagonal line calculation registration display means 1-6 indicates the height of the second floor.

Calculations are made by inputting the height from GL, the approximation angle of concave angle 1 side number, and the setback distance, and the diagonal line of the road and the diagonal line of the adjacent land are calculated.

Calculate the space that can be built that clears all regulations for the altitude diagonal line (north side & i).

The reverse shading calculation display registration means 1-7 clears shading restrictions and diagonal line restrictions by inputting calculation data start time, end time, evaluation interval, shaving interval, measurement interval, grid length, shaving method, etc. Calculate buildable space.

The floor plan creation means performs planning for each floor by incorporating the aforementioned site shape, diagonal line restrictions, and reverse shading conditions.

The shading and other means 1-9 perform the shading calculation after the building is input.

The drawing storage device 1-10 is a storage area for exchanging drawings and data for each phase. This data is used for saving to a medium such as a floppy disk 1-12 or for creating drawings by outputting from a plotter.

〔motion〕

The operation of displaying three-dimensional data of diagonal lines and reverse shadows while two-dimensionally registering them in a planar plan will be described with reference to the flowchart of FIG.

First, the site and legal condition data are input, calculated and displayed, and the diagonal line reverse shadow data registered as 3D data is read (2-1), and the read data is used to create a floor plan. I'm doing a dataset in common < (
2-2), Step 2-3 compares the diagonally shaded equivalent floor heights and the floor plan floor heights. At this time, high floor height, etc.
Since the floor plan's floor height is the height of each floor, both must be corrected to the height from the GL.

When the equivalent floor heights and floor plan floor heights are compared and found to be equal, the diagonal lines and reverse shadows at the same height as the floor to be displayed are displayed one by one. Also, by creating a plane for the current floor and entering the floor height when moving to the next floor, diagonal lines and reverse shadows for the created floor (current floor) will be displayed one by one (
2-4).

Also, compare the equivalent floor heights and floor plan floor heights, and if they are not equal, display diagonal lines and reverse shadows at positions that sandwich the height level from the GL of the created (current floor).
2-5), the upper part is indicated by a dotted line and the lower part is indicated by a solid line at the sandwiching position. Next, the diagonal line/reverse shadow displayed in 2-42-5 is 2-
In step 6, the data is registered as two-dimensional data in the two-dimensional workshop. It is displayed as much as the floor plan is created up to the top floor in steps 2-7.

Figure 3 shows the model of the current floor for which the floor plan was created in step 2-4. When the height from the GL of the 3rd floor of the road around Site 1 matches the height of the GL of high-grade lines such as diagonal lines and reverse shadows, it will look like this figure.

If the height of the plane 5vIj from GL does not match the height of the GL of the diagonal line/reverse shadow, as in the case of 2-5, the upper dotted line is shown in FIG.

A diagonal line/reverse shadow is displayed as a solid line at the bottom.

While creating a floor plan in this way, diagonal lines and reverse shadows for floor heights are displayed, and legal conditions can be met by creating a floor plan within that frame. This makes it possible to check the building coverage ratio and floor area ratio under legal conditions.

〔Effect of the invention〕

As explained above, the present invention enables the construction of buildings by taking into consideration not only site data, legal data, and surrounding maps, but also diagonal lines and reverse shadows on each floor when creating architectural drawings using an architectural CAD system. You can create a floor plan for each floor while checking the building coverage ratio and floor area ratio, which are important under regulations. Therefore, the creation of floor plans, which are the basis of architectural drawings, not only reduces the risk of consistency of drawings and design changes, but also has the effect of checking building regulations and improving the efficiency of drawing preparation.
