Split body - Can it result in a common face??
Split body - Can it result in a common face??
(OP)
Is anyone aware of a way to split a feature on a solid-body such that the result is still a single solid-body, but that has two coincidental faces?
Hmmm ... if that sounds confusing ...
Essentially I have a shell with an internal 'boss' and want to split the 'boss' in two such that in a subsequent operation, a trim-body would then leave each half of the 'boss' with its correct shell half.
I intend to wave-link the model into four variants on which I can perform this trim-body (to give me an upper-half, a lower-half, an upper-mirrored-half and a lower-mirrored-half).
For privacy reasons I can't post the model - but I have made a mock-up (see attached) to test out the principal.
I'm attempting to split the 'boss' in the blue body using the orange plane. The squiggly split-face represents the subsequent trim-body.
Am I barking up the wrong tree with my work-flow?
Any help gratefully recieved.
Regs,
Jon

The more I stare at it, I can't help thinking there is something in my work-flow that doesn't feel right.

However, if what you're attempting to do is create something for a simulation analysis, there are approaches which we support as part of the creation of FEM models which will probably give you what you're looking for, but you will need the help of a CAE expert, which I'm not, for advice on how that's done.

I have found that if one of the boss extrudes starts at 0.01mm then I get effectively what I want ... but being an engineer I feel this is a bit of a bodge.
Yes Cowski - I have greatly simplified the example.
There are 11 bosses, on four different planes, and with slightly different geometry between some of the bosses.
Ideally I'm trying to keep all this detail on one model rather than duplicate it across all four.
I think I may define a surface which completely defines the split-line and then wave-link this along with the main body.

Otherwise, you could split the body using the wavy face, then use the syncronous "Replace Face" to fix up the bosses.
I have attached a nx7.5 part (I don't have access to nx6 anymore) showing this.
This might be a moldwizard tool though... in which case you can accomplish the same thing by 1) extract a copy of the solid, then 2) use "Trim Body" to trim one-half and finally 3) use "Trim body" again on the extracted body for the opposite half.
