标准摘要
[中文适用范围]: ISO 10303 的这一部分指定了对集成资源的解释,以满足定义具有显式拓扑边界和完全定义几何形状的面的要求。 以下内容属于 ISO 10303 本部分的范围: ——3D 几何; ——B样条曲线和曲面; ——圆锥花序; ——基本曲线; ——基本曲面; ——折线; ——曲线; ——雕刻表面; ——参考 pcurves 的曲面曲线; ——扫掠表面; ——扭曲的曲线; ——无界几何; ——几何变换; ——使用拓扑来绑定几何实体。 以下内容超出了 ISO 10303 本部分的范围: ——除了表面参数空间中 pcurve 定义之外的 2D 几何; ——折线和 B 样条曲线以外的有界曲线; ——B样条曲面以外的有界曲面; ——偏移曲线和曲面。 [外文原描述]: This part of ISO 10303 specifies the interpretation of the itegrated resources to satisfy the requirement for the definition of a face with explicit topological bounds and fully defined geometry. The following are within the scope of this part of ISO 10303: — 3D geometry; — B-spline curves and surfaces; — conics; — elementary curves; — elementary surfaces; — polylines; — pcurves; — sculptured surfaces; — surface curves referencing pcurves; — swept surfaces; — twisted curves; — unbounded geometry; — geometric transformations; — use of topology to bound geometric entities. The following are outside the scope of this part of ISO 10303: — 2D geometry other than for the definition of a pcurve in the parameter space of a surface; — bounded curves other than polylines and B-spline curves; — bounded surfaces other than B-spline surfaces; — offset curves and surfaces.
