I’m a new user trying to get Rhino to re-create a curved shape. In my mind it should be the same as creating a boat hull from cross sections, so that is how I have approached it.
I am drawing what is very much like a half hull. I have a series of cross sections taken from a model, and I want to loft a surface over the curves.
If I use “Loft” command, it is close except for 1 problem. The surface does not extend all the way to the edges of the curves.
If I try “SubD loft” the result is similar to loft, except there is an additional problem of the program trying to create a corner where the surface meets the last curve, which is on a different plane. And I haven’t been able to remove this corner after the fact.
SubD 2 rails follows the rails as it should, but two problems. First the surface becomes wavy for no apparent reason. (I re-built curves with same number of control points, checked direction.)
Second, visually, both rails start at a point and end at a point, but SubD won’t loft to a point…so I have to chop up the rails so I can designate the ends of the rail as the last curve. But I can’t have 2 curves intersecting, so I have to extend the rail slightly past the last cross section curve, then cut it to create the end of the part. This leaves a defect in the surface, similar to the regular SubD loft.
Any help would be appreciate. Maybe there is a simple answer, but this is my first time using the program. It seems like it should “just” work, but so far I haven’t been able to crack it.
