Hello,

I am struggling with a group of curves that I need to loft. In order to Loft the curves I need to rebuild them to have the same amount of control points. However, when I rebuild them they lose the flat areas and the edges become rounded. See Attached images.

I was hoping someone had a suggestion on what I could do to solve this issue.

I really appreciate any help you can provide.

That’s going to turn all of your smooth curves into segmented polylines - not sure that is what you really want…
