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非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。-基本曲线类型为直线、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；-基本表面类型平面、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；-非流形。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。

This part of ISO 10303 specifies the interpretation of the integrated resources to satisfy requirements forthe description of geometric shapes by means of non-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 curve types line, circle, ellipse, parabola, and hyperbola;— intersection curves;— polylines that consist of at least three points;— the elementary surface types 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;— non-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.
