Hereinafter, the present invention will be explained based on illustrated embodiments.

FIG. 1 is a block diagram of an interactive automatic drafting device according to an embodiment of the present invention. In the figure, parts that are the same as those shown in FIG. 5 are given the same reference numerals, and explanations thereof will be omitted. 16A', 16

, 17C'' is an interactive automatic drafting device 17 shown in FIG.
A, 17B, and 17C are different from each other in the control section 16A'.
, 16B”.

16C'', and the other functions are the same.

Also, the main computer 18 is almost the same. In addition to the functions of the control units 16A, 16B, and 16C shown in FIG. 5, the control units 16A', 16B', and 16C' are provided with a function of determining paper numbers and areas, and a function of converting coordinate values. . These functions will be described in the explanation of the operation of this embodiment below.

Next, the operation of this embodiment will be explained with reference to the plan view of the drawing area shown in FIG. 2 and the flowchart. Second
In the figure, reference numeral 20 indicates a drawing area (drawing area) of the interactive automatic drawing device 17A'. 21 is the origin of the coordinate system of the drawing@M area 20. Reference numeral 22A denotes a sheet for drawing an overall structural diagram drawn interactively in the interactive automatic drafting device 17A'. 22B and 22G are sheets for drawing partially enlarged diagrams and 9 parts diagrams that are conventionally stretched on the interactive automatic drawing devices 17B" and 17C' and are drawn interactively. The paper 22A is stretched in the drawing area 20. If there is still room after installing the paper sheets 22B and 22C, it is possible to stretch these sheets 22B and 22C.In this way, the interactive automatic drafting devices 17B' and 1
Paper 22B and 22C stretched on paper 7C' are paper 22A.
By also extending the drawing area 20 of the interactive automatic drawing device 17A', the drawing person can examine the entire structure drawing, partially enlarged drawing, and parts drawing at the same time without moving.

By the way, during or after the above study, the drawn partially enlarged drawings and parts drawings are often studied separately, or drawings that are further enlarged are prepared. In this case, these drawings are created using an interactive automatic drafting device 17B'.

It will be considered in 17C. The control unit 16A'(16B',16C') of the present embodiment is configured taking such circumstances into consideration. Below is paper 22A.

22B and 22C are stretched and a partially enlarged view is drawn on the paper 22B, the operation of the control unit 16A' will be described.

First, the paper number and paper area of the stretched paper 22A are determined (step S+ shown in FIG. 3(a)).

For this purpose, the plotter assigns a specific number, for example "01", to the sheet 22A. Also, point a+ at the lower left corner of paper 22A
(reference point), point az (tilt point) at the lower right corner, and point a3 (ill point) at the upper right corner are detected by the cursor. These coordinate values are the coordinate values of the coordinate system of the drawing area 20.

Paper 2 by reference point aI + slope point a2 and area point a3
The area of 2A is determined. The coordinate values of these points and the sheet number "01" are stored in the storage section of the control section 16A' as sheet information (step SZ). Similarly, paper 22
B, 22C paper number, e.g. r02J, r03J
is determined, and its reference point bI + CI + slope point b
2+02 and the paper 22B by detecting the coordinate values of area point b3+CI.

The area 22C is determined (steps S3 and S5), and the paper information thereof is stored in the storage unit. (Steps 34.36).

Next, in order to draw the assumed figure on the paper 22B, the drawing person outputs coordinate values and drawing commands to the control unit 16A'' in the same manner as in normal operations (step S7).The coordinate values in this case, for example, the coordinate values ( XI, YR) are the coordinate values of the coordinate system of the drawing area 20.The control unit 16A'' uses these coordinate values (XB
, Yn) is determined based on the paper information stored in the storage unit (step S8), and since this paper number is 102, the coordinates with the coordinates (XB, YE) as the reference point are set as the origin. Convert to system coordinate values (XB'', YB') (step sq).

Since such coordinate system transformation is well known, detailed explanation will be omitted. Transformed coordinate value (x,'.

Y, ゛) is output to the main computer 18 together with the paper number "02" and other drawing commands (step S, .).

The processing in the main computer 18 is the same as the conventional one, but the coordinate values (Xn', YB') are stored in the storage device 18 MB because the paper number is "02". That is, the coordinate values (XB', YB') are processed as coordinate values of the coordinate system of the interactive automatic drafting device 17B.

Next, when the plotter outputs a plotting command, the main computer 18 outputs the necessary instructions, paper number "02" and coordinate value (X
B'+Yn') is output to the control section 16A'. The control unit 16A° is configured to input these command data.
Step 511) shown in Figure (b), the input paper number "0"
1", the paper information of the paper 22B is retrieved from the storage section, and the coordinate values (XB', Ys') are converted to the coordinate values (xn, YB) of the coordinate system of the drawing area 20 (Procedure SI
□). Then, based on these coordinate values and the command input in step Sl+, a drive signal is output to the drafting mechanism (step S, 3). As a result, a desired figure is drawn on the paper 22B.

Drawing on the paper 22C is carried out in the same way, but the coordinate value conversion in that case is a conversion between the coordinate system of the drawing area 20 and the coordinate system with the reference point c1 as the origin, and the main computer At 18, the coordinate values are stored in the storage device 18M.

The partially enlarged drawings that were considered or are being considered in the automatic interactive drafting device 17A are displayed in the automatic interactive drafting device 17B.
When reproducing the partially enlarged drawing in the interactive automatic drafting device 17B, the partially enlarged drawing is stored in the storage device 18MB of the main computer 18 as coordinate values in the coordinate system with the reference point of the paper 22B as the origin. This can be reproduced on the paper by stretching the paper and outputting a drawing command. The same applies to reproduction in the interactive automatic drafting device 17C''.

In this way, in this embodiment, the control unit is provided with the functions of determining the paper number and paper area and converting the coordinate values.
Paper belonging to another interactive automatic drafting device can be stretched over the drawing area of one interactive automatic drafting device, and the drawings can be managed independently. They can be examined simultaneously on the same surface, improving work efficiency. Furthermore, since the range of the paper has been determined, even if a position outside the paper range is mistakenly specified with the cursor, it can be determined that it is an error and it can be eliminated.

In addition, in the description of the above embodiment, an example of an interactive automatic drafting device that is composed of a coordinate detection mechanism and a drafting mechanism using a writing instrument is illustrated, but the invention is not limited to this, and it may be composed of a coordinate detection mechanism and a display mechanism. The present invention can also be applied to those that are

Furthermore, in the explanation of the above embodiments, an example was explained in which all of the control units of an interactive automatic drafting device are provided with the functions of the present invention, but it is possible that only the control units of some interactive automatic drafting devices are provided with the functions. You can also do this.

〔Effect of the invention〕

As described above, in the present invention, since the control section of the interactive automatic drafting device is provided with the area determination means and the two coordinate value conversion means, the drawing area of one interactive automatic drafting device can be
By providing an area that corresponds to the drawing area of other interactive automatic drafting devices, drawings in this area can be managed independently from others, thereby allowing multiple figures to be considered simultaneously on the same plane. Work efficiency can be significantly improved. Furthermore, even if coordinates that do not belong to any area are specified by mistake, this can be eliminated.
