Mmmmmmmmmmmmmkay........I seem to be unable to do an extrude cut up to a cylindrical surface. I seem to remember this working in the past?
It's the hexagon pictured below: it needs to cut through the boss and not through the cylinder. If I choose up to next, it goes through the wall of the cylinder. If I choose up to surface and select the cylindrical surface, it goes through the cylinder to the far wall. I've attached an image for clarity.
Anyone have a clue they could share with me? Greatly appreciate it!
edit the boss feature and uncheck merge results in the PM.
rollback to after the boss
use the combine feature, with the add option selecteded
