Element Tree: Transition Plies

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

Introduction to Transition Plies

Transition between plies is a way to shorten and extend plies created from the same boundary to create a transition effect relative to a transition chain. For the transition curve, you must select a chain of edges that is common to all the selected plies.

Feature Element Tree for the Transition Plies Feature

The element tree for the Transition Ply feature is documented in the header file ProCmpstPliesTrans.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_CMPST_PLIES_TRANS_TYPE	transition_type	Specified using the enumerated data type ProCmpst_plies_transTransition_type.
PRO_E_CMPST_PLIES_TRANS_REFS	plies_refs	ProArray of ProReference
PRO_E_CMPST_PLIES_TRANS_OFFS_ARR	offsets_arr	ProArray of ProCmpst_plies_transOffsets_cmpd
PRO_E_CMPST_PLIES_TRANS_ARR_CMPD	offsets_cmpd	Specified using the enumerated data type ProCmpst_plies_transOffsets_cmpd.
PRO_E_CMPST_PLIES_TRANS_PLY_REF_ARR	plies_ref	ProReference
PRO_E_CMPST_PLIES_TRANS_OFF_ARR	offset_arr_col	PRO_VALUE_TYPE_DOUBLE
PRO_E_STD_CURVE_COLLECTION_APPL	transition_ref	ProCollection
PRO_E_CMPST_PLIES_TRANS_PAT_SETT	pattern_settings	Specified using the enumerated data type ProCmpst_plies_transPattern_settings.
PRO_E_CMPST_PLIES_TRANS_OFFSET	offset	PRO_VALUE_TYPE_DOUBLE

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_PLIES_TRANS.

•

PRO_E_STD_FEATURE_NAME—Specifies the feature name.

•

PRO_E_CMPST_PLIES_TRANS_TYPE—Specifies the transition type and is defined using the enumerated data type ProCmpst_plies_transTransition_type. The valid values are:

○

PRO_CMPST_PLIES_TRANS_TRANSITION_TYPE_PATTERN=1

○

PRO_CMPST_PLIES_TRANS_TRANSITION_TYPE_CUSTOM=2

•

PRO_E_CMPST_PLIES_TRANS_REFS—Specifies the reference to the transition plies using ProArray of ProReference.

•

PRO_E_CMPST_PLIES_TRANS_OFF_ARR—Specifies the transition offsets of the selected plies relative to the selected reference.

•

PRO_E_CMPST_PLIES_TRANS_ARR_CMPD—Specifies the constant offset between the edges of subsequent plies.

○

PRO_E_CMPST_PLIES_TRANS_PLY_REF_ARR—Specifies a chain of edges to define the reference for transition offsets. You can select only chain that is common to all the selected plies. When you move the cursor over a chain it will highlight when it is a transition chain.

○

PRO_E_CMPST_PLIES_TRANS_OFFS_ARR—Specifies a chain from the highlighted chains.

•

PRO_E_STD_CURVE_COLLECTION_APPL—Specifies the transition references using the ProCollection object.

•

PRO_E_CMPST_PLIES_TRANS_PAT_SETT—Specifies the pattern settings using the enumerated data type ProCmpst_plies_transPattern_settings. The valid values are:

○

PRO_CMPST_PLIES_TRANS_PATTERN_SETTINGS_BACKSLASH=1

○

PRO_CMPST_PLIES_TRANS_PATTERN_SETTINGS_SLASH=2

•

PRO_E_CMPST_PLIES_TRANS_OFFSET—Specifies a chain of edges to define the reference for transition offsets. You can select only a chain that is common to all the selected plies. The system highlights the possible transition chains.
