So I've put this basic body shape together, and am trying to import it into Alibre so I can shell it and add features. I can't do anything with the imported body because there are "convexity points" (many, like more than 20) along the two sweeping curves that make up the saddle shape, with the blend between.

I've tried changing the blend, moving the saddle shape, to no avail.

Can anybody help?

Thanks!
