ABSTRACT:
To simplify the solid model selection work of the user. An image processing unit prepares a cell decomposition model from three orthographic view data, a link of individual cells C1, C2, C3, C4, . . . in the prepared cell decomposition model is detailed referring to lines E1, . . . represented on the three orthographic views, and a solid model is constructed according to a non-conflicting cell combination.
