Hi. I’m completely new to Shapr3d.

I’d like to create a 3D mountain range. I’ve traced ‘contour lines’ using splines (which I believe are closed as when I select each of them the whole shape is selected, not just the outline). I have the shapes spaced approximately 1 to 2mm apart on the z axis. I thought I’d be able to loft them up into the shape of a mountain but I’m getting an error message  
“Lofted body has self intersection in at least one of its intersections”

This is my top view

Thanks in anticipation.
