I'm trying to make a miter cut on the end of this tube but SW won't let me.  Pretty simple cut but just won't happen.  I can make a blind cut up to a certain distance but can't cut all the way thru.  If anyone has the time to try this, make an extruded cut with sketch8 and let me know if you can cut, "through all".

I'm running SW 2012 SP4

Thanks
