标准摘要
[中文适用范围]: ISO 10303 的这一部分指定了对基本边界表示模型定义的通用资源的解释。 以下内容属于ISO 10303本部分的范围: ——elementary_brep_shape_representation的定义,这是由一个或多个manifold_solid_breps组成的表示,每个manifold_solid_breps都用基本几何和完整的显式拓扑定义; ——在此类 B-rep 模型的面定义中使用的曲线和曲面的无界几何定义; ——B-rep 模型拓扑结构的定义; ——3D 几何; ——B 代表; ——基本曲线,这些是直线或圆锥; ——基本_表面; ——几何变换; ——折线; ——无界几何; ——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: ——2D 几何; ——折线以外的有界曲线; ——有界表面; ——偏移曲线和曲面。 该 AIC 独立于任何工业应用领域。 [外文原描述]: This part of ISO 10303 specifies the interpretation of the generic resources for the definition of an elementary boundary representation model. The following are within the scope of this part of ISO 10303: — the definition of an elementary_brep_shape_representation , this is a representation composed of one or more manifold_solid_brep s each of which is defined with elementary geometry and complete explicit topology; — the definition of the unbounded geometry of curves and surfaces used in the definition of the faces of such a B-rep model; — the definition of the topological structure of a B-rep model; — 3D geometry; — B-reps; — elementary curves, these are line s or conic s; — elementary_surface s; — geometric transformations; — polyline s; — unbounded geometry; — use of topology to bound geometric entities. The following are outside the scope of this part of ISO 10303: — 2D geometry; — bounded curves other than polyline s; — bounded surfaces — offset curves and surfaces. This AIC is independent of any industrial application domain.
