Description

[Detailed description of the invention]

The present invention relates to a drawing output method for an engineering workstation (hereinafter abbreviated as EWS).

[Conventional technology]

Conventionally, there was a drawing output method for this type of EWS as shown in Fig. 7. Fig. 0 is an explanatory diagram related to the hardware;
The figure is an overall configuration diagram of general hardware. In FIG. 6, 1 is a system bus for control and data, 2 is a display device such as a CRT, 3 is a magnetic disk device for auxiliary storage, 4 is an optical disk device for storing drawings, and 5 is a central processing unit ( (hereinafter abbreviated as CPU), 6 is the main memory, 7 is a mouse and keyboard as operation input devices, 8 and 9 are drawing input devices for small drawings and large drawings, respectively, 10 and 11 are for small drawings, respectively and a drawing output device for large-sized drawings, and 12 is a control unit that processes drawing data. here,
The above 4.6 is simply referred to as memory. Next, the operation will be explained. First, the drawing data inputted from the drawing output device 8 or 9 is stored in the optical disk device 4 for drawing storage via the system bus 1 according to the control command of the limiting section 120, and is subjected to reduction processing, for example, bit The entire drawing is displayed on the display device 2 by performing thinning, line thinning, etc. Further, the input drawing data is read out from the optical disk device 4 and output to the drawing output device 10 or 11 at the same size. However, if the drawn drawing is large, the entire drawing displayed on the display device 2 at a reduced magnification is output as a hard copy of the screen via the output device 10 or the printer.

[Intelligence B that the invention attempts to solve]

Since the conventional EWS drawing output method is configured as described above, a drawing output device for large drawings is required in addition to a drawing output device for small drawings, and the EWS and drawings are If the output device is laid out at a separate location, it will be very inconvenient for business purposes. Further, if a drawing output device for large drawings is not installed, the entire drawing must be reduced to fit the output paper, and if the entire drawing is simply reduced, it becomes difficult to see the fine details. Furthermore, drawing output devices for large-sized drawings have problems such as being large in size and expensive. Incidentally, as an approximation technique, there is one shown in Japanese Patent Publication No. 1-46903. The present invention has been made to solve the above-mentioned problems, and its object is to provide an EWS drawing output method that allows division and partial output of large drawings without reducing them.

[Means to solve the problem]

In the drawing output method for an engineering workstation according to the present invention, when a control unit receives drawing data from a drawing input device, the size of the drawing is classified according to a command from an operation input device, and the drawing data is determined to be smaller than a predetermined size. The drawing data is output as is from the output device, and if the drawing data exceeds a predetermined size, it is automatically reduced by the reduction processing section, or if necessary, it is divided by the division processing section, or partially processed by the partial processing section. Processed data is stored in a memory, and the data stored in the memory is transferred to an output device in response to an output command from a control unit and output as a hard copy.

[Effect]

When the size of the drawing is instructed by the operator, the EWS in this invention automatically divides the large drawing only into drawings larger than a predetermined size based on the instruction. Also, reduce the size if necessary. Thereafter, when the operator specifies parts of the divided drawings to be output, the corresponding drawings are sequentially output as hard copies from the output device.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, the same parts as in FIG. 7 are designated by the same reference numerals. In FIG. 1, 12 is a control section for drawing data processing, which is composed of an input processing calculation section 12a, an output processing calculation section 12b, and a display processing section 12c. has been done. Reference numeral 3 denotes a reduction processing unit that reduces the entire drawing, 14 a division processing unit that divides the entire drawing into a plurality of small drawings, and 15 a partial processing unit that extracts only necessary parts from the entire drawing. Further, in the case of the present invention, a drawing output device especially for large-sized drawings may not be provided. The hardware configuration is the same as that shown in FIG. 6 described in the conventional example. The operation of the present invention will be explained below with reference to the flowchart shown in FIG. First, the operator sets an input drawing on the drawing input device 8 or 9 and inputs the drawing size from the operation input device 7. When the input processing calculation unit 12a receives the drawing manual data, the control unit 12 classifies the size of the drawing based on the input of the drawing size, calculates the magnification, and stores the results in the optical disk device 4 or the main memory 6. . For example, A3
Small drawings smaller than the size are output as they are to the output bag [10 or 11 (step 5TI). In addition, in the case of a large drawing equivalent to Al size, the reduction processing section 13 automatically reduces the drawing, and if necessary, the division processing section 14 executes division or the partial processing section 15 performs processing, and the processing results are An arbitrary item is selected and specified from (step 5T2). for example,
In the case of division processing, as shown in FIG. 4, the drawing input data of the A1 drawing stored in the optical disk device 4 for drawing storage or the main memory 6 is combined with the output paper A4 drawing to 8 as shown by the dotted line. Divide into sheets and output one sheet at a time from output bag flo or 11. In the case of partial output, a portion of the A1 drawing is partially output as an A4 size portion as shown in FIG. 3 (step 5T4). At this time, the part surrounded by the dotted line can be freely moved and specified, and then only the specified part is output. In the case of reduction processing, the reduction processing is performed by means such as bit thinning and line thinning according to the reduction magnification of the reduction processing unit 13, and after reducing the entire A1 drawing to one-eighth as shown in FIG. 5, for example, Output on A4 paper (step 5T5). Then, each of the drawing data subjected to the partial, divided or reduced processing is transferred to the output device 10.11 according to an output command from the operation input device 7 and output as a hard copy (step 5T6). Further, in the above embodiment, a case has been described in which a drawing is output after being subjected to partial, division, and reduction processing, but the same effects as in the above embodiment can be achieved even when a large drawing is divided and inputted.

【Effect of the invention】

As described above, according to the present invention, if an input drawing is larger than a predetermined size, it is automatically divided into multiple small drawings and output, so it is easy to use hardware even without an expensive output device for large drawings. Not only can it be copied, but since there is no need to reduce the size of the entire drawing, it is possible to clearly read thin parts that are difficult to see by partially outputting the drawing.
