[Symbol on Drawing] FIG. 2 is a diagram showing an example of a facility diagram.

FIG. 2 is a partially enlarged view of an equipment drawing drawn in A3 at a scale setting of 1/100. For example, in a conference room, a symbol of a differential spot type sensor is described. ing.

Originally, the CAD drawing is arranged such that the data of the symbols relating to the equipment for disaster prevention facilities are arranged in a size corresponding to the actual size of the plan view, and at the time of printing, if the scale is set to 1/100, it is reduced to 1/100. , Print out. Therefore, at the time of printing, the device symbol (graphic) with an appropriate size is registered in the CAD program in advance, and the registered symbol is enlarged by a predetermined multiple according to the scale setting of the drawing used at the time of printing. , This enlarged symbol is C
It should be sufficient if it is placed in the AD drawing.

In practice, the reciprocal of the scale is not used as a multiple for enlarging the symbol. That is, for example, when a 1/1 symbol (a 1-fold symbol, which is an appropriate size for printing) is registered in advance as a symbol of a heat sensor, and the symbol is arranged in a drawing with a scale of 1/100. , The symbol registered above is 1
Instead of enlarging it to 00 times, the registered 1/1 symbol is reduced to 120 times (100 ×
1.2 times), 200 times at 1/200 scale, 240 times at 1/300 scale (300 x 0.8)
The CAD screen is arranged in an enlarged manner. In this way, when printing, the smaller the size of the room, the easier it is to arrange the smaller symbols, and the larger the room, the easier it is to see the symbols. The magnification is not a fixed value but can be set by the designer as a numerical value depending on the state of the plan view, and can be arranged as a symbol smaller or larger than the setting.

[Scale Setting and Symbol Recall] FIG.
In the above embodiment, as the scale setting, 1/1, 1 /
It is a figure which shows the example which is displaying on a screen that four kinds of 100, 1/200, 1/300 can be selected.

If it is desired to use a scale other than the set paper scale, the other scale is set. To change the scale, select the scale in the same manner as above with the command of "scale reset" shown in FIG. When selecting this command, you can choose whether to automatically change the size of the symbol.

FIG. 4 is a diagram showing an example in which a symbol call command for calling a disaster prevention symbol is displayed on the screen in the above embodiment.

At the time of printing, the recalled symbol is registered in an optimal 1/1 scale, is enlarged by a predetermined multiple according to the scale of the paper setting, and is arranged in the plan view.

[Symbol Enlargement / Reduction Tracking Means] Next, a procedure for changing the size of the symbol when the scale is changed will be described.

Here, a case will be described in which a drawing is created at a scale of 1/100 and the scale is changed to 1/300.

(1) A desired scale is selected by "scale reset" in the scale setting command shown in FIG. That is, 1/300 is selected.

(2) The attributes of each figure arranged in the plan view shown in FIG. 2 and the like are read out. The attributes of the figure are shape data, size data, connection point data, center point data, information indicating whether or not it is a symbol, and the like.

(3) If the figure is a symbol as a result of discriminating the attributes of the figure, the original multiple is used to restore the scale to 1/1. That is, since the scale before change is 1/100, it is multiplied by the reciprocal of 120 times corresponding to 1/100, thereby returning the symbol to 1/1.

(4) Enlarge to 1/1 scale with a multiple of the selected scale. In other words, since the scale is reduced to 1/300,
The 1/1 symbol is multiplied by 240. After all, the scale is 1
When changing from / 100 to 1/300, the symbol size is relatively doubled.

(5) The enlarged symbol is placed in the drawing on the data.

[Wiring Symbol Tracking Procedure] FIG. 5 is a diagram for explaining a procedure for following the wiring arrangement when the scale is reset in the above embodiment.

Note that FIG. 5 shows a differential type spot type heat sensor as a symbol.

The internal area of the outer shape of the symbol is used as an erasing area, and in this erasing area, the display other than the symbol such as wiring is erased. Further, wiring connection points are set at four points above, below, left and right of the outer shape of the symbol, and the wiring is connected to these connection points.

When the symbols are arranged in the drawing, they are arranged with the center of the symbol as a reference. That is, when arranging symbols having different scales, the center position of the symbols is fixed.

(1) First, an instruction to enlarge or reduce a symbol or an instruction to change a symbol arranged in the drawing into another symbol is input.

(2) The wiring is specified based on the attribute of the line connected to the symbol. Here, the attribute of the line is, for example, wiring as a signal line or a power supply line, and a region to be wired is selected based on the attribute of the line.

(3) When reducing the symbol, the connection point near the end of the wiring is detected. That is, the connection point of the symbol existing near the end of the wiring is detected.

(4) The position of the end of the wiring is changed to the detected connection point.

(5) On the other hand, when enlarging the symbol, the wiring existing in the erase target area (inside the outline of the symbol) is discriminated. That is, the portion of the wiring that overlaps the symbol is determined.

(6) The wiring (wiring existing in the erasing target area) overlapping the symbol is removed, and the end position of the wiring is changed to the outer shape position of the symbol.

[Others] FIG. 6 is a diagram showing a part of the call symbol list.

The call symbol shown in FIG. 6 is the drawing device DS.
It is an example of 1/1 symbol registered in the CAD program of 1.

FIG. 7 is a diagram showing the relationship between the symbols relating to the heat detector and the names of the devices.

In FIG. 7, the "symbol" is the drawing device DS.
It is a symbol registered in 1 and is a "file name".
Is a registered name of the symbol, and “Name” is a general name of the disaster prevention device according to the symbol.

By the way, in the conventional CAD program,
When changing the drawing size or scale during design, it is necessary to individually change the size of the already arranged symbols.

However, in the above embodiment, when the drawing size or scale is changed, the size of the already arranged symbols changes accordingly, so there is no need to change the size of the symbols individually, No need to arrange.

Further, according to the above-mentioned embodiment, if the basic symbols as shown in FIG. 6 are registered, the size of the registered symbols can be determined by a necessary multiple, and various symbols can be obtained. It can correspond to various scales.

Further, in the conventional CAD program, the symbol of the disaster prevention device arranged on the architectural drawing is drawn so that the signal line and the power line are in contact with each other, and this symbol is changed by changing the model or the scale during the design. When the size of the symbol changes during the design, the end of the wiring must be changed.

However, in the above-described embodiment, since the symbol size is automatically changed, it is possible to greatly reduce the design labor by changing the end portion of the wiring at the same time.

In addition, when a symbol is deleted in the middle of design, when two wirings in contact with the symbol to be deleted face each other, the wiring from one side and the wiring from the opposite side are Since the work of making a book is automated, the work of deleting symbols is simplified.

Furthermore, when changing a symbol, the wiring to be connected to the newly arranged symbol is automatically arranged, so that the work is simpler than the work for correcting the original wiring.

In some cases, the symbol may be automatically changed by changing the scale. In this case as well, the wiring is automatically changed, so that the wiring changing operation is simple.

In the above-mentioned disaster prevention equipment CAD program, 1/1 symbols are registered in advance as symbol registration,
Although it is enlarged in multiples corresponding to the scale of the drawing and placed in the CAD drawing, not only 1/1 but also 1/100 symbol, 1/200 symbol and 1/300 are registered as symbols. It is also possible to register all symbols for use in the CAD drawing and select a symbol that fits the scale of the drawing and place it in the CAD drawing. At this time, it is not necessary to calculate the size of the actual room by a multiple when arranging the symbols, and the figure in the drawing is clear even if the width of expansion / contraction is large. However, the number of registered symbols will increase to a multiple of the scale.

Regarding the procedure for changing the size of the symbol when the scale is changed, in the above-mentioned CAD program for disaster prevention equipment, the figure of the symbol in the drawing is used to restore the value to 1/1 and enlarge it again in multiples. However, the processing may be a process of enlarging the registered figure corresponding to the symbol figure to 1/1 by the changed multiple, and replacing the figure with the same position. At this time, the process of returning the symbol graphic to 1/1 becomes unnecessary. However, the symbol to be changed must be registered.

Further, regarding the procedure of changing the size of the symbol at the time of changing the scale, when the scale is changed from 1/100 to 1/300, it is 120 times back and 240 times, so it is doubled in the end. Such relative magnification may be set in combination with a reduced scale, and the symbol graphic in the drawing may be doubled as a relative multiple. At this time, the process of returning the symbol graphic to 1/1 is unnecessary,
Moreover, the symbol to be changed may not be registered.

[0072]

According to the present invention, in the CAD program, when the scale is changed, it is not necessary to individually change the size of the already arranged symbols, and it is necessary to rearrange the symbols. Thus, there is an advantage that it is easy to change the scale during design.
