THREE-DIMENSIONAL CAD DATA CREATION SYSTEM AND THREE-DIMENSIONAL CAD DATA CREATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a three-dimensional CAD data creation system and three-dimensional CAD data creation method capable of easily synthesizing a plurality of three-dimensional point group data without disposing a target.SOLUTION: The three-dimensional CAD data creation system includes: a shape measurement device 2 that measures three-dimensional point group data representing a surface shape of a measurement object O at a plurality of measurement points; a synthesizer 3A that synthesizes a plurality of three-dimensional group data to create synthesized point group data; and a three-dimensional CAD data creation device 5A that, when creating the three-dimensional CAD data of the measurement object O from the synthesized point group data, creates a continuous and integrated three-dimensional CAD data for the measurement object O that is non-continuously represented in the synthesized point group data and has a continuous substance.
