generative modeling for Rhino
The extrusion should not have any bending the components should be straight.
1)When I subdivide the surface on UV it does not follow the outline of the given surface.
2) And also the extrusion doesn't not follow the surface path.
Any ideas how I can succeed the above result?
1, You might have worked with an trimmed surface. If you read about Nurbs surface and how trim surface is defined, you will know that the UV curves are not changed after trimming operation.
Try use simple lofted surface for this.
2. The way you moved the lines to X direction and loft them back is not sophisticated enough.
Simplest way if they are all parallel to Z Direction: Try move the curves to Z (move up), loft the two sets, and then extrude the resulting surface to X Direction. You may even want to extrude to X 1 unit, move the solids to -X half unit, to position them on the center line.
:) Thank you for the tips Victor :) i really didnt know the trimming part :) it works fine now
or use the rhino command, rebuild on your trimmed surface.
