Preform hole improvements

I was adding holes into a vacuum forming mold only to realize that I can’t bulk select and/or edit them together afterwards.

I understand that this function was probably added just for vent hole functionality and thus bulk editing wasn’t a problem…but I think it would be nice to be able to do this.

For context, I don’t have a STEP or solid body of this model, only an STL from a client and I need to add holes into the mold appropriately for vacuum forming of deep cavities :slightly_smiling_face:
