I was creating an assembly and I had 2 intersecting parts. I wanted to use the intersecting feature to remove the overlaying layer. But, under Insert, I don't see any of the other features besides the simple ones. I went to Customize in Tools and dragged Intersect into the Command Manager. But, it's grayed out/disabled so I can't use it. The features are there in a parts file but not in an assembly file where I need it.
How can I re-enable it? Thank you.
