Element Tree: Core Ply
This section introduces and shows how to create, redefine and access core ply features in Creo TOOLKIT.
Introduction to Core Ply
A core ply is a thick ply made up of materials such as foam, paper, aluminum, or honeycomb structure. It is extracted from a large sheet and cut along a boundary. To create a core ply, you must first set up the Composite Design environment.
Feature Element Tree for the Core Ply Feature
The element tree for the Core Ply feature is documented in the header file ProCmpstCore.h. The following figure demonstrates the element tree structure:

The elements in this tree are described as follows:
•  PRO_E_FEATURE_TYPE—Specifies the feature type and the valid value is PRO_FEAT_CMPST_MAN_PLY.
•  PRO_E_STD_FEATURE_NAME—Specifies the feature name.
•  PRO_E_CMPST_PLY_BASE_QUILT—Specifies the selection of layup surfaces.
•  PRO_E_CMPST_MAN_PLY_TYPE—Specifies the core ply type. The ply type is defined using the enumerated data type ProCmpst_man_ply_type and has the valid values as:
○  PRO_CMPST_MAN_PLY_TYPE_OPT_MANUAL_PLY—Use PRO_E_AREA_BOUNDARY to specify the boundary.
○  PRO_CMPST_MAN_PLY_TYPE_OPT_ZONE_BASED_PLY—Use PRO_E_CMPST_MAN_PLY_ZONES to specify the boundary zones.
•  PRO_E_AREA_BOUNDARY—Specifies the boundary.
•  PRO_E_AREA_BOUNDARY_LOOPS—Specifies the loops that represent the outer boundary of the ply and its inner islands.
•  PRO_E_AREA_BOUNDARY_LOOP
•  PRO_E_STD_LOOP_COLLECTION_APPL—Specifies the boundary chains using the ProCrvcollection object.
•  PRO_E_DSGNTAREA_CREATION_FLIP—Specifies the flip direction.
•  PRO_E_CMPST_MAN_PLY_ZONES—Specifies the boundary zones. The valid value is PRO_QUILT for laminate zone feature.
•  PRO_E_CMPST_MAN_PLY_CMPND
○  PRO_E_CMPST_MAN_PLY_MTRL—Specifies the material of the ply.
○  PRO_E_CMPST_MAN_PLY_ORNT—Specifies the angle of the ply with respect to X-axis of the rosette. The valid range is.-360.0 to +360.0.
○  PRO_E_CMPST_MAN_PLY_DROP_OFF—Specifies the drop-off. The valid range is 0 to MAX_DIM_VALUE.
○  PRO_E_CMPST_MAN_PLY_NAME—Specifies the name of the ply object that is shown in the Laminate tree.
○  PRO_E_CMPST_MAN_PLY_SEQ—Specifies the ply sequence.
•  PRO_E_CMPST_PLY_ROSETTE—Specifies the selection of PRO_SURFACE, PRO_QUILT, PRO_CSYS, PRO_LOG_CSYS.
•  PRO_E_CMPST_CORE_SET_ARR—Specifies the array of loop or an edge to which the taper dimensions will be applied to.
•  PRO_E_CMPST_CORE_SET—Specifies a loop or an edge to which the taper dimensions will be applied to. The reference selected to apply the taper dimensions can only be a sub-set of the selected boundary references.
○  PRO_E_CMPST_CORE_D1—Specifies the horizontal taper direction.
○  PRO_E_CMPST_CORE_D2—Specifies the vertical taper direction. The valid range is 0 to material thickness
○  PRO_E_STD_CURVE_COLLECTION_APPL—Specifies the taper chains using the ProCrvcollection object.
