Stretch Solid Body Around A Radius?

[doncasters]

Hello all,

I hope this makes some sense, it's not too easy to explain....

I have a step file supplied to me by a customer. It is a portion of an annular component. It is machined and assembled in to a ring. In order to compensate for some contraction during our process I need to 'stretch' the body. A simple scale body will increase the radius of radial faces and this is unacceptable. What I want to do is stretch the body whilst maintaining the size current size of the radii. eg if I currently have a 9 degree portion I like to have a 9.9 degree portion.

Suppliers with other CAD packages can use an arc of desired length to drive an edge which will stretch the whole body accordingly. I am using NX9, is there a similar tool available to me. I have hunted around but cant find anything.

Many thanks,

Richard.

Have you tried Synchronous Modeling?

So do those who use NX. You did not supply us with the picture, but I'm rather confident that you are after this.

Apologies - this is my first time back in the office since your replies...

Synchronous modelling was good, but wouldn't quite yield the results I was after.

Global shaping hit the nail on the head - thanks.
