I can't Boolean Diff these two solids. I suspect it's because of the cross-over nature of the heart sweep. The black rail used for the sweep is a continuous curve.

Can anyone recommend a way to accomplish this design?

Will it Boolean Diff in Rhino or some other program?



I'm out of forum space to post a 3dm file, but happy to email. I think any swept "pretzel" shape will have the same issue.
