I have an assembly where this blue brown slab protrudes into the purple body. It insists I have a clearance when I cut it out and I actually need some sort of clearance when the parts are injection moulded in plastic. So I have mated the parts, indented them with a little clearance, and then mated them again. I am a bit worried that moving them for the second mate will cause a 'second cut'. I have also got the clearance wrong and would like to expand it which will break a hundred mates all over again. I don't know what the correct procedure is for that. Any help welcome!
Also how would you line that brown face up with bright purple face in an assembly?
Huge thanks.
There is. If a component is in the position you want it you can right-click on it in the feature tree and choose "Fix" from the drop-down, or use the Lock mate.
