ISO 10303-109:2004规定了用于表示装配模型的构件之间的详细几何关系的资源结构，包括构件之间的几何约束。
以下内容属于ISO 10303-109:2004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；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几何约束、运动学副和运动学路径等元素方面的表示；在装配模型中起锚点作用的固定构件的表示。
以下内容超出了ISO 10303-109:2004的范围:
组件及其组成部分的产品结构配置；公差信息。
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;
