Architects want the free shape for their architecture from the ordinary structural design. Free shape design needs the structural design agent system for their probability of structural limit. This report deals with the both the scanning of a free shape and the creation of its structural analysis data. As results, the smooth surface needs the scanning accuracy of 1/50-length for the short span of scanning object. The complicated surface needs the scanning accuracy of 1/4-wavelength of its surface. The useful file format is 3DMF. The smooth surface decreases the total number of nodal points into 10% of original scan data, and it can be analyzed with shell elements. The complicated surface needs 3Ds olid analysis with hexahedral solid elements.
