Hi guys! Its me again..just a quick question.. what do you guys think happened to my subassembly here? Im trying to add a cutt/fill subassy, setting the slope to 2:1 for both cut and fill..if I look into my object viewer there is a portion that drops extremely low..I have already checked my EG (my target surface) and it seems fine. Any suggestions to solve this one? Again Many thanks in advance to those who will answer.
