Method of generating CAD data for evaporative pattern having frame structure
First Claim
1. A method for generating CAD data for an evaporative pattern having a frame structure, the method comprising:
- preparing rod data that represents a rod, the rod data including rod body data representing a shape of a rod body and terminal data representing a shape of a rod terminal that is disposed at an end of the rod body;
allocating a plurality of the rods in a virtual 3-dimensional space generated by a computer so as to overlap the rod terminals;
generating joint shape data by merging the terminal data of the overlapped rod terminals in the 3-dimensional space; and
extracting the rod body data from the rod data of the rods allocated in the 3-dimensional space.

Abstract
A method for generating CAD data appropriate for designing an evaporative pattern having a frame structure is provided. The method includes, allocating, generating joint shape data, and extracting rod body data. Rod data includes rod body data representing a shape of a rod body and terminal data representing a shape of a rod terminal disposed at an end of the rod body. In the allocating, a plurality of the rods is allocated so that the rod terminals overlap each other in a 3-dimensional space in computer. In the generating, the joint shape data is generated by merging the terminal data of the plurality of rod terminals overlapped. In the extracting, the rod body data is extracted from the rod data of the rods allocated in the 3-dimensional space. The joint shape data and the rod body data obtained by such processes correspond to the CAD data of the evaporative pattern.
