I can't use loft between two profiles that are not similar to each other (for instance, a circle and a rectangular in two different parallel planes). When I loft them, an error message is appeared and a 3D body with an abnormal shapes appears. Catia recommend me that I have to use guide. I don't know how to draw those guides so I use some points on the circle and connect them to the corner of the rectangular as the guides but catia doesn't confirm them. please tell me how I can create guide for lofting.
