Hello Dale,
I’m primarily using SrfMorph, but am unable to maintain a constrained vector n the W domain.
Yes, I’m working on a few options and Sporph is one of them. My target surfaces are iso-trimmed from a single surface.
I’ve also used paneling tools and have displaced the paneling grid in a single direction, but I’m still experiencing a lot of twisting in the resulting geo in areas with more underlying surface curvature.
