标准摘要
[中文适用范围]: ISO 10303 的这一部分指定了用于表示装配模型的组成部分之间的详细几何关系的资源构造,包括组成部分之间的几何约束。 以下内容属于 ISO 10303 本部分的范围: ——形状方面关系与其表示的关联; ——实例化装配特征关系与其表示的关联; ——以装配几何约束、运动学副、运动学路径等元素表示实例化装配特征关系在geometric_representation_item级别的详细几何信息; ——在装配模型中起锚定作用的固定构件的表示。 以下内容不属于 ISO 10303 本部分的范围: ——组件及其组成部分的产品结构配置。 — 公差信息。 参见 ISO 10303 本部分的第 5.2 条。 [外文原描述]: ISO 10303-109:2004 specifies the resource constructs for the representation of detailed geometric relationships between constituents of an assembly model including geometric constraints between constituents. The following are within the scope of ISO 10303-109:2004: association of shape aspect relationship with its representation; association of instanced assembly feature relationship with its representation; representation of detailed geometric information of instanced assembly feature relationship at the geometric_representation_item level in terms of elements such as assembly geometric constraints, kinematics pair and kinematics path; representation of the fixed constituent which plays the anchor role in the assembly model. The following are outside the scope of ISO 10303-109:2004: product structure configurations of assemblies and their constituents; tolerance information.
