Unroll a Cylinder?

[Hockeyguy]

Hi,

Is there a way to take a cylinder and unroll it into a flat sheet?

I have NX7.5 and NX8.0.

Thanks in advance!

Assuming that your cylinder already has a thicknes (if not use Shell command)

Cut it open along the axis with a marginal width (e.g. 0.2mm)

Go to NX Sheet Metal

Convert to sheet metal

Preferences - Sheet Metal - change bend neutral factor to 0.5 (then your flat pattern will result in a correct part)

Define your flat pattern (and if needed flat solid)

export flat pattern to GEO (NX 7.5) and/or DXF (NX8.0)

Frankbe,

Thanks for the response and info!!!!

Yes the"tube" has thickness. How do I place a cut into it, the tube will have a but welded joint after it is rolled.

How did you come up with the "bend neutral factor to 0.5" value?

Thanks again!

Another option, you could "unwrap" the edge curves of the cylinder. I think you'll have to divide the face, similar to the "cut" suggested earlier, and have a datum plane tangent to the OD to unwrap the edge curves on to.
