This happens when creating secion views in drawings. I have a fairly large assembly of a mold design. When I select my line segments for a section view and insert section line-the arrows don't show up, so there is no way to determine whether I need to double click on it to flip the direction. I can create the view and then the arrows show up. I can then flip direction as needed.
As far as bugs go, this is not a show-stopper. However, it's a little un-nerving-especially the first time. You've just created a section line but you don't really see any indication that you really did in the viewing area-just in the feature manager.
If somebody cares to confirm this, I'd appreciate it. I'll call my VAR Monday with it.
