Hi, I lofted a nurb over several open spline paths, but now I can't thicken it, nor can I subtract it from a solid cube (using the S-Split). In both cases I get the same error message "Unable To Complete Smooth Modeling Operation". What went wrong?

Second question: Is it true that subtracting a nurb from a solid transforms the solid into a hollow "envelope" of 2D surfaces (meaning the cube isn't solid anymore)? Is it possible to split a cube with a nurb without loosing its "solidness"?

Stanton,

You can split a solid with a surface and maintain a solid. The ability to thicken can be limited by the density of the control points in the surface, and the tightness of its curvature. If you choose a small value that should reasonably fit on your surface, and / or if you change the direction to In or Out, does this help?

You may also want to check your object with the Object Doctor tool to see if it has any issues. (Non-Developable surfaces are fine -- they are just curved in two directions and as such can not be easily unfolded...)

If you need further help, you can always zip and email the file to support@formz.com so we can take a look at your specific geometry and thus get you a more specific answer...
