Need help with positioning a rectangular object into a rectangular sink

a_v553

Hey y'all! I am relatively new to Onshape and need some advice. I am designing a component that requires a rectangular nameplate to be positioned in a rectangular sink. They both have the same dimensions as the nameplate should sit flush with the top of the main body Is there any way to do this, whether manually or automatically? Thanks in advance!

There are many different ways to do this. How do you want to be able to change this in the future? Which part do you want to drive the other? What about clearance dimensions/tolerances? How will this be manufactured?

I would use the 'Fastened mate', select the center of the bottom face of the name plate and then select the center of bottom of the sink. Use the rotate option if neccesary.
You can also use any corner of the bottom face for this. I prefere to use centers if possible, this leaves the possibility to add chamfers or blends later on.without breaking the mate.
