Document Type and Number:
Japanese Patent JP2719228
Kind Code:
B2
Abstract:
PURPOSE:To reduce the memory capacity needed for a drawing master file which stores the CAD data by compressing the number of digits of the coordinate position data when the data are transferred from a display memory and stored in a drawing master file. CONSTITUTION:A display memory 11 stores the information including the coordinate position data on the drawing displayed on a display 10. Then a compression processing part 13 is added to compress the number of digits in regard of the coordinate position data stored in the memory 11 together with a store processing part 17 which stores the coordinate position data containing the compressed number of digits in a drawing master file 12, and a restoration processing part 14 which restores the number of digits of the value read out by a read processing part 18. That is, the file 12 holds the coordinate position data containing the compressed number of digits. As a result, the memory capacity needed for the file 12 is reduced.
