标准范围

ISO 10303的这一部分规定了集成资源的解释，以满足以下要求通过流形表面模型描述几何形状。以下内容属于ISO 10303本部分的范围:-3D点；-在曲线或曲面的参数空间中定义的点；-3D曲线；-在曲面的参数空间中定义的曲线；注-此类曲线也称为pcurves或cons，是参数化曲线的首字母缩写和曲面上的曲线。-基本曲线直线、圆、椭圆、抛物线和双曲线；-相交曲线；-由至少三个点组成的折线；-基本表面平面、圆柱体、圆锥体、环面和球体；-通过曲线的旋转或线性挤出产生的扫掠表面；-雕刻的曲线和表面；-使用拓扑实体修剪曲线和曲面；-使用拓扑实体合成曲线和曲面；-曲线、表面和表面模型的复制；-曲线和表面的3D偏移；-2-歧管。以下内容超出了ISO 10303本部分的范围:-无界几何；-自相交几何形状；-2D笛卡尔坐标空间中的几何结构；-点的复制；-没有与相应几何域的关联的拓扑；-非流形。

This part of ISO 10303 specifies the interpretation of the integrated resources to satisfy requirements forthe description of geometric shapes by means of manifold surface models.The following are within the scope of this part of ISO 10303:— 3D points;— points defined in the parameter space of curves or surfaces;— 3D curves;— curves defined in the parameter space of surfaces;NOTE - Such curves are also known as pcurves or cons, which are acronyms for parametrised curveand curve on surface.— the elementary curves line, circle, ellipse, parabola, and hyperbola;— intersection curves;— polylines that consist of at least three points;— the elementary surfaces plane, cylinder, cone, torus, and sphere;— swept surfaces created by rotation or linear extrusion of a curve;— sculptured curves and surfaces;— trimming of curves and surfaces using topological entities;— composition of curves and surfaces using topological entities;— replication of curves, surfaces, and surface models;— 3D offsets of curves and surfaces;— 2-manifolds.The following are outside the scope of this part of ISO 10303:— unbounded geometry;— self-intersecting geometry;— geometry in a 2D cartesian coordinate space;— replication of points;— topology without an association to a corresponding geometric domain;— non-manifolds.
