OFFSET SURFACE

I have a ribbon like surface and want to offset and "cap" after offset.

First of all how can i control the offset direction besides giving plus or minus in a number slider ? Tried to flip normals but doesnt work.....

Second, after offseting I get 2 curves that I need to bridge with new surfaces.

I tried extrude but its difficult to define vectors since the surface twists in space.

Any ideas?

Hello,

I am not sure I understood what you are looking for (I always find it difficult to think without a definition), but I will give it a try.

For the first issue, I suggest that you use scale instead of offset. This way the offset direction is determined by whether your scale factor is smaller/larger than 1.

As for the second one, how about lofting?

Best,

Gesthimani
