Hi all. I do need to calculate the volume of some BREPs, but this ones seems to have some sort of defect and I can’t find what it is the issue. Any help will be appreciated. Best regards.

exported the 3 geometries together as STEP file, imported in Rhino again, and it works
don’t ask me why 
geometries internalised here, just in case: Whats_wrong.gh (51.9 KB)

This parts are imported from .SLDPRT files.
ahh ok, maybe that’s the origin of the issue
with the original non-step parts, it looked like the polysurfaces were perfectly closed in Rhino, also exploding and joining them resulted in Closed Polysurfaces as one should expect
but Rhino itself was also failing returning Analyze → Mass properties → Volume and also Volume Centroid… so I believe this is not GH related (both R7 and R8 → GH Volume component was failing on the original polysurfaces) but somehow a Rhino-import thing related to that particular Solidworks file type?

Can be, but never happened to me this before. Just reimported the parts and I do have the same result. All the other parts are calculated the volume excepting this three ones.
