The issue I'm encountering is that the square tube is not trimming to the round pipe, as you can see here:
Here is my feature tree for reference, as well as another view of the square tube clipping through the pipe without trimming:
Any ideas? I'd really like the square tube to trim to the "edge" of the pipe, a flat trim would be fine, a rounded trim would be a bonus.
I know I could get the result I want by making separate weldment part files, doing a circle cut-extrude in the corners and then marrying the two part files together in an assembly file, but that feels like an un-necessary step.
