Can't mirror across a smooth face?

chris_moris

Hello,

I am unable to mirror the part below across the smooth face (bisecting the circular center piece). I get an error that boolean can't resolve the part.

What am I doing wrong?

Thanks,

Chris

Hi @chris_moris, here is an example of how to do this:
https://cad.onshape.com/documents/9c74589f3a557e941ea09391/w/c08b520e00da9263aa050b3e/e/26d14c5aa1...

There were some edges or vertices not lining up well, which were causing errors in the mirror. 

It's important to use "best practice" when modeling in Onshape because it is very precise. For example having sketches and vertices almost line up is not good enough, it must be perfectly constrained for everything to work as intended. Once you learn, it all becomes much easier. I recommend following the Learning Pathways for learning best practices and how to be the most efficient at Onshape.
