标准范围

ISO 10303的本部分规定了综合资源的解释，以满足使用三维线框模型表示产品形状，线框模型由一组贝壳。以下内容属于ISO 10303本部分的范围:-线框模型的表示，由边和顶点的图形描述，其中边只在顶点相交；-线框模型由一个或多个壳表示，这些壳不得重叠或相交，除非在它们的顶点或边缘；-在三维坐标空间中定义的点；-在三维坐标空间中定义的曲线，包括b样条曲线；-单个线框模型或线框模型集合的表示。以下内容不在ISO 10303本部分的范围内:-在二维坐标空间中定义的几何图形；-表面几何；-立体几何；-对已消除结构的引用。

This part of ISO 10303 specifies the interpretation of the integrated resources to satisfy requirements for therepresentation of the product shape using three-dimensional wireframe models which are bounded by a setof shells.The following are within the scope of this part of ISO 10303:— the representation of wireframe models that are described by a graph of edges and vertices where theedges intersect only at their vertices;— the representation of a wireframe model by one or more shells that shall not overlap or intersect exceptat their vertices or edges;— points defined in a three-dimensional coordinate space;— curves, including b-splines, defined in a three-dimensional coordinate space;— the representation of a single wireframe model or an assembly of wireframe models.The following are outside the scope of this part of ISO 10303:— geometry defined in a two-dimensional coordinate space;— surface geometry;— solid geometry;— references to eliminated constructs.
