Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a diagonal dimension display device for writing a distance dimension of one diagonal into a single closed figure or a group of closed figures whose outlines are formed by vertical and horizontal straight lines. More specifically, the present invention relates to a diagonal dimension display device preferably used when designing a floor plan of a building by computer processing represented by a CAD system.

[0002]

2. Description of the Related Art In recent years, in various designs, CAD (computer-ai) composed of a computer system is used.
A ded-design) system is used, and, for example, a house is also being designed using a CAD system. As a design of a house using such a CAD system, specifically, the external shape of the house that matches the site is input and stored, and each living space, that is, the entrance or the kitchen, is stored in the stored external shape. Plan the space such as living room and bedroom. Then, regarding the floor plan designed on the CAD system in this manner, the designed floor plan is output by a printer or the like, and the output is used as it is as a drawing.

By the way, when designing a house, the layout of the foundation is designed in parallel with the floor plan, and the bearing walls such as outer walls are constructed based on the obtained layout of the foundation. As the layout design drawing of the foundation, a line along the outer peripheral surface of the cloth foundation that is usually positioned on the outermost side in the site, or a line at a predetermined position such as a center line or a module line is shown on the plan view. , And those with the necessary dimensions are entered.

Here, the necessary dimensions are, for example, as shown in FIG.
If the placement of the foundation is represented by a simple rectangle, as shown in
The distance dimension of one diagonal line 1, that is, the diagonal line from the lower left to the upper right is entered. Also, this is of course CAD
In the drawing designed by the system, the distance dimension is also entered. In the conventional method, for example, in the case of FIG. 7, the arrows 2 and 2 are entered on both ends of the diagonal line 1 and the lower left corner thereof is entered. A leader line 3 is continuously formed from an arrow 2 located at, and a distance dimension is written on the leader line 3.

It is to be noted that the distance dimension of the diagonal line is entered on the design drawing of the foundation arrangement in this way, when the foundation is constructed at the construction site, the distance dimension or the squareness of each straight line portion and each corner portion is measured. This is because at the same time, the distance of the diagonal line is measured to confirm the distance of the straight line portion and the squareness of the corner portion.

[0006]

However, in the process of entering the distance dimension as described above, in the case of the rectangular figure as shown in FIG. 7, the diagonal line is simply drawn to convert it into the actual dimension. This can be performed by a simple process such as obtaining the length and entering the obtained length. For example, in the case of a complicated shape rather than a simple rectangle as shown in FIG. It is not decided whether to write the distance dimension on the drawing as a representative of the connecting line segment). Therefore, there is a disadvantage that the position of the diagonal line to be written varies depending on the drawing. That is,
The distance dimension of the diagonal line is necessary for confirming the accuracy of the straight line portion and the corner portion as described above. Therefore, the diagonal line that can represent the whole figure, in the case of FIG.
This is because it is preferable to use a diagonal line including the length of each straight line portion as the diagonal line 6 instead of the diagonal line 5 as the accuracy check.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to increase the size of a straight line portion in an entire figure according to a certain rule even in a figure having a relatively complicated shape. It is an object of the present invention to provide a device for displaying the dimensions of a diagonal line which is included and therefore can be approximately representative of the length dimension of the graphic.

It has a function of writing a distance dimension. Here, of course, the actual size is written as the distance size.

Further, the arithmetic processing unit 11 has the following functions.

Next, referring to the flowchart of FIG.
A method of giving a diagonal dimension on a figure by the diagonal dimension display device will be described. First, the auxiliary storage device 12 stores a graphic 20 having vertical and horizontal outlines as shown in FIG. When the graphic 20 is stored, the arithmetic processing unit 11
The figure recognition means a recognizes the stored figure 20 on the XY coordinates and recognizes that the outline of the figure 20 is parallel to the X axis or the Y axis (step A).
1). Here, regarding the recognition of the figure 20 on the XY coordinates, in this example, the figure 20 is recognized in the first quadrant on the XY coordinates, and the most Y-axis of the straight lines parallel to the Y-axis among the outlines. Is recognized so that the distance from the Y axis of the straight line that is closest to the X axis is the same as the distance from the X axis of the straight line that is the closest to the X axis among the straight lines parallel to the X axis.

When the figure 20 is recognized, the vertices 21a, 21b ... In the figure 20 are recognized (step A).
2) Further, among the recognized vertices 21a, 21b, ..., The closest point 22 of the origin closest to the origin O on the XY coordinates is recognized (step A3). Also, each recognized vertex 21a,
21b ... Of the origin closest point 22 on the XY coordinates
The vertices 21a located at the upper right are recognized (step A4). Here, being located at the upper right means that the apex 21a
It means that both the X coordinate and the Y coordinate of are larger than the closest point 22 of the origin. When the upper right vertices 21a ... Are recognized, the maximum distance point 23 farthest from the closest point 22 of the origin is recognized (step A5). In addition,
When there are a plurality of maximum distance points, the maximum distance point is determined by a preset rule, and in this example, the vertex with the smallest Y coordinate is recognized as the maximum distance point 23.

When the maximum distance point 23 is recognized, the actual length of the diagonal line 24 connecting the origin closest point 22 and the maximum distance point 23 (actual size when the foundation is constructed), that is, the maximum distance from the origin closest point 22. The distance dimension L to the distance point 23 is obtained (step A6). When the distance dimension L is obtained, the dimension L is set at a predetermined position of the figure 20, that is, the diagonal line 24 in this example.
Is written on the upper side of a lead line 26 that follows the arrow 25 and extends toward the closest point 22 of the origin (step A).
7).

In such a diagonal dimension display device, the diagonal line 24 selected for dimension display is always a straight line (segment) from the origin side to the upper right on the XY coordinates, and the selected diagonal line 24 is also present. Is the longest of the diagonals connecting the origin closest point 22 and the upper right apex 21a ..., and is therefore sufficiently long in the recognized figure 20, so the selected diagonal 24 is the figure 20.
The length dimension can be almost represented.

FIG. 4 and FIG. 5 are diagrams showing another example of a figure in which the diagonal dimension is written by the diagonal dimension display device of the present invention. FIG. 4 shows the closest point 3 of the origin of the recognized graphic 30.
1 indicates the case on the right side of the XY coordinate with respect to the straight line closest to the Y axis, that is, at the position where the X coordinate is larger than the straight line, and in this example as well, the origin closest point 31 and the maximum distance point 32 are obtained by the respective means described above. The diagonal line 33 connecting to and is recognized,
Further, the actual length dimension corresponding to the diagonal line 33 is written near the origin closest point 31.

FIG. 5 shows the diagonal dimension of a set figure 41 consisting of two closed figures, namely, a closed figure 40a showing a base part corresponding to a porch of an entrance and a closed figure 40b showing a base part corresponding to a main body of a house. In the case of writing, in this example, one vertex of the rectangular closed figure 40a is recognized as the closest point 42 of the origin by the means described above, and the diagonal line 44 connecting this point and the maximum distance point 43 is recognized. Therefore, the actual length dimension corresponding to the diagonal line 44 is the closest point 4 to the origin.
It is written in the vicinity of 2.

In the above-mentioned embodiment, the case where the figure in which the diagonal line is written is the diagram showing the basic arrangement in the house has been described. However, in the diagonal line dimension display device of the present invention, the diagonal line is shown on the other drawings. It can also be applied when writing dimensions.

[0024]

As described above, the diagonal dimension display device according to the first aspect of the present invention selects a straight line connecting the closest point of origin and the maximum distance point located on the upper right of the origin point as a diagonal line, and the distance of the diagonal line is selected. Since the size is written in a predetermined position of the figure, the selected diagonal line is always XY.
It becomes a straight line (a line segment) from the origin side to the upper right on the coordinates, and this selected diagonal line is sufficiently long in the recognized figure. Therefore, the selected diagonal line almost represents the length dimension of the figure. Therefore, for example, when the recognized figure is a diagram corresponding to the foundation arrangement, the distance dimension of the diagonal line is suitable as the dimension used for the measurement for confirming the linear accuracy of the foundation and the squareness of the corner. Becomes Further, since the diagonal dimension can be written by such a simple process, when the device is applied to a CAD system, for example, it can be performed without complicating the system. Since the diagonal dimension display device according to claim 2 corresponds the planar figure showing the basic arrangement of the building with the single closed figure or the aggregate figure composed of a plurality of closed figures, the basic arrangement of the building is designed. At that time, it becomes possible to write the diagonal dimension at the predetermined position on the drawing to confirm the dimensional accuracy of the foundation at the construction site.
Therefore, the production of the design drawing can be further simplified.
