Preserving Feature Properties on UDF Placement
When a UDF is placed the copied features that are included in it preserve their visibility status as set in the source model. UDF features that are hidden in the source model remain hidden after UDF placement.
* The hidden status of a standard hole note is not carried over to the target model.
UDF color and line styles are preserved in the following geometric entities:
Datum curves
Composite curves
Feature properties of a UDF that was created prior to the Pro/ENGINEER Wildfire 4.0 release are not preserved. You can modify the UDF to update the feature properties.
UDF feature properties are always independent. Any updates to the source model features that are done after UDF placement are not passed to the placed UDF.
