Extruding an spiral, rolled sheet.
Extruding an spiral, rolled sheet.
(OP)
Hi.
I would like to create a shape (solid or surface, I don't mind) like a rolled sheet.

I've also tried in both cases to project the helix to a sketch, but the extrude command doesn't accept that sketch either.
I'm sorry for posting several times, eng-tips doesn't allow me to upload several times at once.

If the spiral curve is a single curve then extrude it for the distance (width of the material) that you want, then utilize offset in the extrude menu to get the thickness of the material that you need.

Now, if I want to wrap a curve around it I can't with the wrap command. It needs a cone or cylinder.
How would you do it?

As for wrapping curves around a spiral surface, you can actually do that in NX 9.0 (see image below) if instead of creating the surface using Extrude, you make a copy of the spiral curve and create instead a Ruled surface using the new (for NX 9.0) 'Developable' Alignment option. Because we also enhanced the Wrap/Unwrap Curve function in NX 9.0 to work with 'Developable' surface as well as Cylinders and Cones (by definition, Cylinders and Cones are already 'Developable', meaning that they can be 'mathematically flattened' without distortion).
