General Limitations
Note the following limitations:
Creo Parametric won’t move mounting holes associated with a component.
Workaround: manually move the holes or ignore them until ECAD sends updated hole locations via an EDMD IDX response.
Creo Parametric has a 32 character limitation.
Workaround: Prevent the ECAD teams from using Package Names longer than 32 characters in their library. Alternatively, make sure that the hint.map file is setup to handle the long names and maps them to shorter .prt names.
Mixing IDF and EDMD IDX is a limitation when working with Pro/ENGINEER Wildfire 4.0 only. IDF is used for baseline exchange and EDMD IDX is used for incremental exchange between baseline on Component and Board changes only.
