Assembly Cuts Failing on regeneration

[jledesignltd]

Hi there, Im using Pro E wildfire v 2.0 and im having some issues with assembly cuts.

I have a bunch of basic laminated panels that are used in the creation of a box. These planes are assembly parts that have several extrusions made at assembly level.

When a high level is regenerated, these assembly cuts fail to "appear", creating a regeneration failure. Once the children of the cuts are suppressed, they can then be resumed.. and the model is fine again.

Anyone have any clue what is going on?.. its killing me trying to find a solution to this problem, as when you have 500 components hanging off the clut, it gets a bit messy..

Hope to hear from someone soon

Thanks
Jason

Don't use massive assembly cuts, it can seem like a good idea but they are not robust, have massive overhead and are very prone to failure.

We tried to go down that path one with a brazed assembly that had all kinds of machining afterwards. It would all regen fine, but when you saved it and tried to retrieve it everything would fail. We ended up making a 3rd part that was a merge of the two parts and then doing all the machining at the part level. I still use those parts and make new instances 15 years later & everything keeps working.

Unfortunately the model has been running for the past two years without issue, its only been the past week where somethings changed to cause this failure.

The cuts are integral in a very large assembly. Its the typical case of ProE letting you build a model on a feature that seems very stable, only for it to fail once your past the point of no return. Hopefully i dont have to roll the model back to an earlier version.
