I have a parametric 3d model in creo 11. The family table has around 8 instances. Can I export all of them to stl format in one go?
The door in general has differing curves on the left and right side. I managed to get the front shape down, but I've no idea how thin it out into a curve. Anyone have tips or ideas on how I can cut off this excess material? I am very lost.
Thank you in advance!
I am looking to create a pattern as like in the pictures. I've tried dimension and table pattern but I can't just get it right. How can this be done ?
Just checked and my drawing now has 287 sheets? I dont know how. I seem to be only able to delete them one by one. Is there a way to get rid of these?
thank you.
