Greetings all!

The task is to wrap the solid body to the reference surface. Shape of the wrapped solid should be correct, e.g. all perimeters of the edges must not change. What is the correct tool for the task?

I attached a part file to this message.

on part level you can extact ( the name of the button) all bodyfaces.
My interest is the workflow behind. It is because it must not to be done in Nx like in your other cat system.
I have seen this mess with diamler they not really turn the cat system they turn Nx to V5.
 
on partlevel down in the single part you can
Menu Insert -> asotiative copy -> extract geometry
in the dialog extract geometry type choose -> Face
face option -> body face ... select body...
detailed enough?
regards
 
That took a little more effort (had to create an additional sketch) but look at the attached model anyway.

Note that with the next version of NX (the one after NX 8.5) we've made a couple of enhancements which will allow you to create this model with 1 Sketch, 1 Surface and 1 Wrap operation. Basically you would have created a single-faced Ruled-Surface using the new 'Developable' option and then created a single Sketch tangent to the face of the surface and then create a single wrapped-curve feature as you will now be able to Wrap onto a 'Developable' surface as well as a Cone and Cylinder (after all, that's one of the characteristics of being 'developable').

Remember, the real enhancement is the ability to define a mathematically 'developable' surface, which ironically UG supported 30+ years ago, but which got lost when the freeform surface modeling architecture was moved from being based on 'parametric cubics' (a type of Coons patch) to Bezier patches and NURB's. Of course we didn't have any sort of wrap/unwarp functionality back then so it was more of a mathematical 'check in the box' than actually having integral downstream support, like we're going to be doing with the next release of NX, starting with at least Wrap/Unwrap.
