STEPデータ交換システムにおける曲線・曲面のデータ検査方法

抄録

This paper describes functions that are needed for exchange of curve and surface data by using STEP data exchange system. In some cases, data conversion of curve and surface data must be done using approximation and occurrence of numerical error is inevitable. To predict the case and take suitable measure for it, a detection method is given. Also, an implementation method to detect the error is proposed.
