Stretch Solid Body Around A Radius?

Stretch Solid Body Around A Radius?

Stretch Solid Body Around A Radius?

(OP)
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?

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.
