Element Tree: Splice Plies

This section introduces and shows how to create, redefine, and access splice plies features in Creo TOOLKIT.

Introduction to Splice Plies

You can splice one or several plies in 2 pieces by defining whether the spliced plies are touching or overlapping each other. For overlapping splice plies, you need to define the overlapping direction and offset. For multiple splice plies, you need to define the stagger, its direction and offset.

Feature Element Tree for the Splice Plies Feature

The element tree for the Splice Plies feature is documented in the header file ProCmpstSplc.h and has a simple structure. The following figure demonstrates the element tree structure:

The following table describes the elements in the element tree:

Element ID	Element Name	Data Type
PRO_E_FEATURE_TYPE	Feature Type	PRO_VALUE_TYPE_INT
PRO_E_STD_FEATURE_NAME	featname	DATATYPE
PRO_E_PLIES_REF	plies_coll	ProArray of ProReference
PRO_E_STD_CURVE_COLLECTION_APPL	chain_coll	ProCollection
PRO_E_CMPST_PLY_OVERLAP_OPT	cmpst_ply_overlap_opt	PRO_VALUE_TYPE_INT
PRO_E_CMPST_PLY_OVERLAP_DIM	cmpst_ply_overlap_dim	PRO_VALUE_TYPE_DOUBLE
PRO_E_CMPST_PLY_STG_OPT	cmpst_ply_stg_opt	PRO_VALUE_TYPE_INT
PRO_E_CMPST_PLY_STG_DIM	cmpst_ply_stg_dim	PRO_VALUE_TYPE_DOUBLE
PRO_E_CMPST_PLY_SPLC_FLIP	cmpst_ply_splc_flip	PRO_VALUE_TYPE_INT

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_SPLC.

•

PRO_E_STD_FEATURE_NAME—Specifies the feature name.

•

PRO_E_PLIES_REF—Specifies the plies to splice or dart.

Note

Splice plies does not support external references. If you want to use external references for creating a Splice Plies feature, you need to use the External Copy Geometry feature which is created in the composite solid as a local reference.

•

PRO_E_STD_CURVE_COLLECTION_APPL—The curve that defines the splicing or darting trajectory.

•

PRO_E_CMPST_PLY_OVERLAP_OPT—The plies that are created as a result of splicing the original ply, touch each other but do not overlap. This element is defined by the enumerated data type ProCmpst_splc_overlap and has the following valid values:

○

PRO_CMPST_SPLC_OVERLAP_NO=0

○

PRO_CMPST_SPLC_OVERLAP_YES=1

•

PRO_E_CMPST_PLY_OVERLAP_DIM—Value or dimension of the overlapping offset.

•

PRO_E_CMPST_PLY_STG_OPT—The plies that are created as a result of splicing the original ply, are staggered. This element is defined by the enumerated data type ProCmpst_splc_stagger and has the following valid values:

○

PRO_CMPST_SPLC_STAGGER_NO=0

○

PRO_CMPST_SPLC_STAGGER_YES=1

•

PRO_E_CMPST_PLY_STG_DIM—Value or dimension of the staggering offset.

•

PRO_E_CMPST_PLY_SPLC_FLIP—Toggles the direction of both the overlapping offset and the stagger offset.
