yes faces, there is a difference in gh between polysurface (brep) faces and brep. Brep faces are individual surfaces, Breps are a collection of faces as the whole.
I suppose I can get more specific in the description, but at least now you know why. Sometimes as developing you forget the user doesn’t always know Rhinocommons terminology.
That’s a lot of mumbo-jumbo to offset a bunch of tangent faces joined together…
Why is it such a hair-pulling contest to do that in GH when it is a snap in Rhino ?
Making solids in Gh is really darn complicated because of that, and also because there isn’t the “Two sides” option, nor the “make solid” option.
That’s why I wanted to use your tool, but this time, it failed because of tolerance and my geometry being far from the origin.
Not blaming you or anything, but damned ! this is really gruelling.
but the method I posted above is what Rhino uses to offset the polysurfaces as connected. I chose not to incorporate it because I don’t yet want to alienate the Rhino 5 users. I think parakeet plug-in which is for Rhino 6 has the offset brep as a component already if you rather not go the c# route.
it failed because of tolerance and my geometry being far from the origin.
I think my component would not work for what you want to do either way.
If it works then it is a surprise to me, the method I am using does not keep faces together. Or maybe you are talking about the boolean in which case you will have to ask McNeel team.
The other advantage of why I use brepface instead of surface offset from rhinocommon is that I can use trim data for things like holes, surface offset will ignore trim data.
