METHOD AND DEVICE FOR COMPILING SINGLE FACE OF PLATE MODEL IN THREE-DIMENSIONAL CAD SYSTEM AND STORAGE MEDIUM STORING PROGRAM OF SINGLE FACE COMPILING METHOD OF PLATE MODEL IN THREE-DIMENSIONAL CAD SYSTEM

摘要

PROBLEM TO BE SOLVED: To compile the respective plate parts of a three-dimensional solid model without considering plate thickness by designating the plate part of the three- dimensional model of a product and compiling the face as a two-dimensional plane. ;SOLUTION: A separation object picture generation part 21 reads three-dimensional paper model data from a model data file 35, separates the face of a compiling object from the three-dimensional paper model, stores it in a separation object face data file 37 and updates and stores the remaining three-dimensional paper model from which the face of the separation object is cut, into the data file 35. A data conversion part 23 reads data on the face of the separation object, which is stored in the data file 37, converts it into two-dimensional wire frame data and stores it in a two-dimensional wire frame data file 39. A two-dimesonal compiling object face generation part 25 reads two-dimensional wire frame data stored in the data file 39, switches the mode of a display picture 7 to a two-dimensional coordinate system and generates the graphic of the face of the compiling object in the two-dimensional coordinate system.;COPYRIGHT: (C)2001,JPO
