When importing ECAD EMP/EMP file using Investigate Geometry & Placement options, components in pattern are replaced with individual components instead of retaining the pattern

When importing ECAD EMP/EMP file using Investigate Geometry & Placement options, components in pattern are replaced with individual components instead of retaining the pattern. All relationships with children are then broken. This is VERY serious, especially panel cutouts are that reference the shape of components in patterns that ProE then simply removes! These cutouts will then fail and everything will be broken.

Product Management considers this an improvement!

Updating ECAD from EMN/EMP files ruins the design intent put into the Creo model. Component placement constraint will also be replace by simple translation/rotation measures as specified in the EMN file.

We keep the PCB assemblies dumb. The importance of data exchange is more important than design intent.

If a component is referenced for cutouts references will remain after the update import, if a mapping exist between the ECAD footprint and the 3D model.

Bjarne,

We have panels with many cutouts. Sometimes 30-40. Many of them may be the same LED repeated 10 times. We speed of the process by patterning the component and then the cutout which references the component.

What I am suggesting is that ProE will first check the patterns to see if anything changed. If it didn't, leave the patterns alone. If the pattern can be updated (ie, pattern members, distance, etc), than it should update the values. Otherwise, if it looks like the pattern members are no longer in a pattern placement, than replace them BUT map the references from the old ones to the new ones automatically.

In short, I would like better update/reference handling with this functionality.
