Hi,

I've attached a simple testcase.  In this file, I am hoping to create a lofted boss/base between "loft profile large" and "loft profile small" using guide curves "guide curve working" and "guide curves not working" to shape the loft boundary.  I am able to create a loft just using the sketch "guide curve working" as my sole guide curve, but I do not want to use that guide curve for the entire perimeter.  When I include the sketch "guide curves not working" as one of my guide curves, the lofted base will not build.  There does not seem to be any kind of error message.

I have had a lot of trouble working with lofted base features using guide curves, and any advice or an alternative approach would be appreciated.  This feature will be mirrored in 2 dimensions to create a convex structure, and I have previously done this successfully - this is a modification to my previous design.
