ABSTRACT:
An apparatus automatically generates a solid model from a plurality of plan views. The apparatus includes an extraction unit for extracting information related to surfaces from the plan views, a first generation unit for generating candidate surfaces based on the information extracted by the extraction unit, a second generation unit for generating candidate surfaces and candidate edge lines by obtaining intersecting lines among the candidate surfaces generated by the first generation unit, a third generation unit for generating candidate solids by determining combinations of the candidate surfaces generated by the second generation unit, and a selection unit for collating the candidate solids generated by the third generation unit with the plan views and selecting a matching candidate solid as a solid model.
