Not sure what the “seams” actually are but I’m extruding a nurbs curve and there are vertical lines spanning the extrusion from each input point except seemingly the points second from the end:
in the A curve (curve domain 0 to 16) points are at parameter 0,4,8,12,16
the B curve is divided into 4 parts
you can clearly see the A curve is not evenly divided even if the parameters are sharp and correct
at the same time you can see the parameters at which the curve B is evenly divided
here’s are two awesome ancient but on spot posts from David Rutten himself from his blog:
there’s no Paneling Tools in that definition, but you can get there (and also do other awesome stuff) with that plugin I’d strongly advice to give it a try (in Rhino type PackageManager then search for “Paneling Tools” and it should install)
