Help with swept cut

Help with swept cut

Help with swept cut

(OP)
Running 7.5 with TC integration.  I have a flat plate that I would like to add an o-ring groove to.  On the face I made a sketch of the path.  Perpendicular to the face, I made a sketch of the o-ring groove cross section.  I tried to use the "swept" feature and ran into a minor problem.  It seems the swept command does not allow me to break through the top face of the solid.  Presently my sketch is constrained to the face of the solid...Please see attached

RE: Help with swept cut

Try editing your sketch so that there are some extra curves extending the profile so that it protrudes above the top face of the body.

OK, I edited the sketch such that it produdes above the body.  Strange thing happened.  The parts of the sketch that were within the body subtracted as expected.  The parts of the sketch that are above the body created a body in the shape of the extra portions of the sketch...

RE: Help with swept cut

Without the actual part file it's going to be difficult to determine exactly what's going on or how to make it work.

RE: Help with swept cut

Are you using the 'Swept' or the 'Sweep Along a Guide' function?

I have been using the swept feature and selecting the guide from the dialog box.  Perhapse I am mis-using the tool or maybe I should be using the swept along guide feature???

RE: Help with swept cut

I see what the problem is.  You referred to performing a 'swept cut'.  The problem is that there is NO such operation in NX.  What you've done is create a 'swept body' which then must be 'subtracted' from the base part to create the O-Ring groove.

RE: Help with swept cut

(OP)
If I X-section what I have it appears to have subtracted material with the exception of a very small skin of material.  Any idea how to remove this small skin of material?

Should I have started with a different function?

RE: Help with swept cut

Are you using the dynamic sectioning function?  That may be problematic when there are interfering solids.

Trust me, just go to...

Insert -> Combine -> Subtract...

...select the base solid first and then the Swept Body and hit OK and you'll have what you're looking for.

You were expecting the Swept operation to create a 'cavity', but that's not how it works.  It creates a separate body which is then used as a 'tool', subtracting it from another solid if what you're looking for is a cavity or void.

Ahh, that did the trick.  Definately learned something new today!
Thanks for the help.

RE: Help with swept cut

I looked at your part,
I think you should take a look at Variational Sweep - that has those options and works perfect in this case
