PDM-UG: Relative Orientation and Location of Related Geometric Models
From WikiSTEP
This page belongs to the PDM Usage Guide.
The relative orientation and location of two shape_representations to each other can be defined with the shape_representation_relationship that reference transformations. One might want to specify such transformations to geometrically relate representations of portions of the part shape to relate the shape of components in an assembly structure in order to define the geometric relations.
The PDM Schema supports two methods to define geometric relationships between external models:
- implicitly by identifying two items that establish a reference relationship via an item_defined_transformation,
- explicitly with the help of a functionally_defined_transformation. It is generally recommended that cartesian_transformation_operator be used to define a functionally_defined_transformation.
