Just messing around on Autodesk Inventor V5 with a custom rocker panel (pretty rough....emphasis on "messing"), and I'm trying to insert a 4" tube I created into the hole "cut" from the rocker. I can't seem to create an axis for the rocker opening to align the tube for insertion/mating. The inlet opening was created by lofting two 4" circles, and cutting through the rocker. Is that where I went wrong?
