I wonder if NX9 have any option to make a sweep with a body using a helical curve like solidwords, i've been looking in the features of NX but i can't find it, at his moment the only option that works is pattern along of curve but the result is not the best (see attached image), i hope some solution to this.
PD: I Apologize for my english.
For the moment, it isn't possible. In the version NX9, we have up a roughing this feature but not implemented in NX 9 and 10 perharps NX11.
In the file attache, I build a sweep surface in which I impose a direction. We show the problem for conveying a form such as "a bottle".
This functionality will be interesting for conveying screws not to be confused with the extrusion screws.
Thanks Jhon for you answer, this operation is close to for i'm looking but has a problem when y try to fit in the cavity a bottle for example of diameter 40mm like your tube not(see image) fit because the width is less that diameter, for this reason is useful a operation like i describe in the previous post also the surface is continous and not like the example that I submit.
Basically, what you are trying to do is sweep a cylindrical solid (cross section of the bottle) around the helix, and subtract that "swept solid" from the main cylinder.
Right now, it is not possible to sweep solids bodies to get another solid body.
There may be something you can do to get a faceted representation (e.g. drive an end mill, and get the 3D IPW as a faceted body).
Another option is to (analytically or empirically) get the resulting cross section (possibly an ellipse, possibly something else) and sweep that.
Production: NX10.0.3.5 MP5 + patch/TC11.2
