Attachment Geometry Feature
This section describes how to construct and access the element tree for reattaching geometry when a flexible modeling feature modifies or transforms a geometry selection. It also shows how to create, redefine, and access the properties of the attachment features.
Introduction
When a geometry selection is transformed by a flexible modeling feature, you can reattach the geometry to the model in one of the following ways:
• Extend the surfaces of the geometry selection and the neighboring geometry until they intersect each other, or until the hole where the geometry selection was originally located is closed and the transformed or modified geometry is reattached.
• Create the side surfaces to close the gap between the moved geometry and the hole left in the model.
• Recreate immediate neighboring surfaces maintaining tangency conditions, if the moved geometry and the immediate neighboring surfaces are tangent planes and circles.
The attachment element PRO_E_FLEX_OPTS_CMPND is seen in the following feature types:
• PRO_FEAT_FLEXMOVE (See ProFlexMove.h)
• PRO_FEAT_FLX_OGF (See ProFlexOffset.h)
• PRO_FEAT_ANALYT_GEOM (See ProFlexMag.h)
• PRO_FEAT_FLXATTACH (See ProFlexAttach.h)
• PRO_FEAT_FLEXSUBST (See ProFlexSubstitute.h)
