3-dimensional analysis model forming method and apparatus, 3-dimensional analysis model forming program, and its recording medium

摘要

According to a 3-dimensional analysis model forming method, a 3-dimensional detailed model constructed by a plurality of parts is inputted, the 3-dimensional detailed model is simplified into a shape suitable for layout, and it is converted into a first approximate model (3-dimensional patch approximate model). Further, the first approximate model is converted into a second approximate model (approximate model for analysis) simplified into a shape suitable for analysis by an analysis program and inputted into the analysis program.
