Closed Loop Curve
Creo TOOLKIT provides complete element tree access to create a composite curve that forms a closed loop by selecting chains that exist in a domain.
The Closed Loop Curve tool automatically identifies a loop that can be created from the curves and edges you select. The tool will automatically trim any excess segments of the chains that are not part of the loop.
Some of the elements for this feature type are described below:
Element ID
Value
PRO_E_CURVE_TYPE
Curve type defined by the enumerated data type ProCurveType with the valid value PRO_CURVE_TYPE_CLOSED_LOOP.
PRO_E_STD_FEATURE_NAME
Name of the feature
PRO_E_LOOP_CRV_DOMAIN
Mandatory element. Placement of the curve in the domain. The valid values are PRO_QUILT, PRO_SURFACE, or PRO_BODY.
PRO_E_STD_LOOP_COLLECTION_APPL
Mandatory element. Specify the boundary chains to form the closed loop on the placement.
