So, I created a lofted surface which I used to trim another surface.  It comes into contact with the Front Plane at four points. For 3 of the points, it shows how I want it show but the 4th point of contact, the edge shows as an undercut.  I came from Creo so the process of making this feature is very different. Can anyone take a look at this and see what I'm doing wrong??  Any help would be appreciated.
