Okay, then I know that but problem is that WF1-2 are shaped after fuselage with no problem at all. Maybe not glued in a 90 degrees angle but in that area. 15 mm behind former 2 is a straight measurement and WF2 is in line with Former 2. Problem is that WF3 is a triangle and Okay I can modify it to have the shape of Former 4 with no problems. Al I want is to get this done, Rear wing fillet sheet 1.5 mm thick goes from WF4 and to WF2 in one piece.
