• PRO_E_FEATURE_TYPE—Specifies the feature type and should be PRO_FEAT_GEN_MERGE.

• PRO_E_GMRG_FEAT_TYPE—Specifies the type of General Merge Feature:

◦ PRO_GEN_MERGE_TYPE_MERGE (Merge or cutout feature)

◦ PRO_GEN_MERGE_TYPE_INHERITANCE (Inheritance feature)

◦ PRO_GEN_MERGE_TYPE_REF_LAMINATE (Laminate feature)

• PRO_E_DSF_REF_MDL—Specifies the reference model. It has the following elements:

◦ PRO_E_DSF_EXT_LOCAL_TYPE—Specifies the DSF location type and is of the following type:

▪ PRO_DSF_PLACE_LOCAL type is a local reference to the reference model

▪ PRO_DSF_PLACE_EXTERNAL indicates an external merge, cutout, or inheritance feature.

▪ PRO_E_DSF_SEL_REF_MDL—Specifies a selected reference model.

▪ PRO_E_DSF_PLACEMENT—Specifies the placement of the Data Sharing feature. It contains the following elements:

• PRO_E_GMRG_MATERIAL_OPT—Specifies the general material options. These are listed as follows:

◦ PRO_GEN_MERGE_RMV_MATERIAL—It removes material from the modified (target) model . The material removed is equal to the modifying (source) model.

◦ PRO_GEN_MERGE_ADD_MATERIAL—It adds material to the modified model from the modifying model. The material added is equal to the modifying model.

◦ PRO_GEN_MERGE_INT_MATERIAL—It retains the intersecting material between the modified and modifying models.

• PRO_E_GMRG_VARIED_ITEMS—Specifies a pointer element that defines the inheritance feature varied items and their values. This handle cannot be directly read or modified by . Instead, use the Visit functions available in ProVariantFeat.h to read varied items. To set varied items (after the feature has been created), use the appropriate modification function on an item whose owner is the variant feature model handle (ProVariantfeatMdlGet()). For more information, refer to the section Inheritance Feature and Flexible Component Variant Items.

• PRO_E_GMRG_COPY_DATUMS—True to copy datums with this merge or inheritance feature, false to leave them uncopied.

• PRO_E_DSF_PROPAGATE_ANNOTS—Specifies rules about how to propagate annotations. Refer to the section Feature Element Tree for the Copy Geometry, Publish Geometry, and Shrinkwrap Features for the details. A Shrinkwrap feature is a collection of surfaces and datum features of a model that represents the exterior of the model. You can use a part, skeleton, or top-level assembly as the source model for a Shrinkwrap feature. A Shrinkwrap feature is associative and automatically updates to reflect changes in the parent copied surfaces.

• PRO_E_DSF_DTMS_FIT—Specifies a compound element that indicates the rules for fitting datums in the DSF feature. It is visible for all internal Copy Geometry features) and Shrinkwrap features. This compound element includes PRO_E_DTMPLN_FIT and PRO_E_DTMAXIS_FIT subtrees for any or all of the copied datums. Refer to the section Element Trees: Datum Features for details on the datum fit subtrees.

• PRO_E_DSF_DEPENDENCY—Specifies the dependency type. The values for this element are specified by the enumerated type ProDsfDependency.

◦ PRO_DSF_UPDATE_AUTOMATICALLY—Specifies that the geometry of the DSF feature depends upon the geometry of the parent model used during feature creation. The DSF feature reflects all the changes made in the parent model.

◦ PRO_DSF_UPDATE_MANUALLY —Specifies that the geometry of the DSF feature is independent of the geometry of the parent model used during feature creation. If you update the parent model, the DSF feature does not change.

◦ PRO_DSF_NO_DEPENDENCY—Specifies that there is no dependency between the geometry of the DSF feature and the geometry of the parent model used during feature creation.
