Geometry extraction for Composites parts recognizes some Composites-specific GCDs: Ply GCD and Core GCD. In addition, the Component GCD has several properties that are process-group-specific or have process-group-specific meanings.

Some of the Ply and Core properties are extracted from CAD file metadata (for example, the Material Name, Orientation, and Sequence for a given ply). A Composites Mapping File allows aPriori to convert the metadata into GCD property values that can be used by the cost model. The default mapping file supports CAD files that contain published Fibersim or CPD ply design data. The Mapping File is a fully customizable XSLT file. If you need to support additional metadata formats, contact aPriori Professional Services.
