Hi! I've been facing a problem for a couple days now and i can't find a sloution on my own.. I need to create a loft which would be made from two shapes. The thing is that the loft twists around the center of itself. Why is it hapening? And how could i get rid of that?

I am using a simple straight line on one side as guide curve but it still twists for some reason...

Any advice?

Thanks in advance
