I am having a problem with sweep feature, it is like sweep at 1% slope spiral down one step, but the rectangular cross section is twisting weirdly outward. Attached hereby are the model and the pictures of the model.
I want the cross section to remain straight as it is at the start of the sweep feature until it ends. Can anyone help me out in that? Or know a way to do what I want to do and how to do it?
