I've been pulling my hairs for the past 2 days. For some reason, I can't do lofted Boss/Base with my design. I know I'm missing something but I can't figure out what that is. I'm trying to draw this RC wing but it won't let me loft it. Either can't build error or some other error. I can only use one of the guidelines to loft it.
The second I added the second guideline in front, the shape of the loft change to this.
Can someone help point to me what I miss that caused the drawing to refuse to loft. Please help? Many thanks in advance.
