I tried to make a curved shape with a flat side at the top and the bottom. This should be easily done by a loft. I made profiles and made the loft. I did play with the start/end constrain a little bit to give it the desired curved shape. The basic shape seems good, but on closer look can be seen that it's asymmetrical(see screenshots). I don't understand how this can happen. The profiles are all symmetrical and the connectors seem to be placed right.
I hope someone can help me out
