[Detailed Description of the Invention] [Industrial Application Field] The present invention is a CAD system that performs drawing processing using a computer.
(COMPUTERAIDED DESIGN) relates to a data creation device for a plotter that outputs drawings.

[Prior Art] In conventional CAD, drawings are completed on a screen through interactive processing with an operator, and the figures completed on the screen are stored in a predetermined figure memory.

As a method for outputting drawings created through interactive processing to a plotter, there is a method in which figures stored in the figure memory are output to a plotter using the same CAD program during CAD work.

In such a CAD, when an operator commands the CAD program to output a plotter, the CAD program outputs the graphic data stored in the graphic memory at the same level as when drawing a line or circle on the screen. It is converted into plotter data and written to the auxiliary storage device.

This process is performed on all of the graphic data stored in the graphic memory that is to be output to the plotter, and when the conversion process is completed, the CAD program allows the operator to accept the next work. be done.

[Problems to be Solved by the Invention] As described above, in conventional CAD, a program that creates drawings on the screen while interacting with an operator is capable of generating figures stored in the figure memory by the above-described plotter output command. It also converts data into plotter data and writes it to the auxiliary storage device. In this way, the process of converting the graphic data stored in the graphic memory into plotter data and writing it to the auxiliary storage device handles a much larger amount of data than the process of drawing on the screen through interactive processing with the operator. However, there was a problem in that the operator had to wait until the process of converting the graphic data stored in the graphic memory into plotter data and writing it to the auxiliary storage device before starting the language processing.

The present invention has been made in view of the above points, and an object of the present invention is to provide a plotter data creation device that can perform drawing processing in parallel through drawing output and interactive processing.

C. Means for Solving Problem] In a drawing device that draws a figure on a display screen based on key input data input from a key input unit and stores the figure data in a figure memory, A partial file creation means selects only the necessary data when outputting to the plotter from the figure memory in response to a plotter output command, and writes data to a partial file, and the data written by the temporary file creation means is used as input to create data for the plotter. a plotting job starting means for starting a job to generate a plotter; and a plotter for producing plotter data in a plotter data memory based on a part of the file created by the temporary file creating means, which is started by the drawing job starting means. This is a data creation device for a plotter, comprising a data creation means.

[Function] In a CAD system that performs drawing creation processing on the screen through interactive processing and also stores graphic data in the graphic memory, it is possible to perform drafting processing through interactive processing even when outputting the graphic data stored in the graphic memory to a plotter. There is.

That is, in order to eliminate the waiting time when converting CAD data into plotter data, this processing is executed in parallel as a separate job from the interactive program.
