I use Houdini to design parts for 3D printing. The requirement for 3D printing is manifold geometry ("watertight" models, no single edges, no "T" connections between polys etc). I have a polygonal object, the result of many Boolean operations. From my, human view, it looks "watertight": it's a polygonal shell that encloses a definite region in space, with no holes. But my slicing software (Simplify3D) gives me "non-manifold" verdict, high-lighting in red many of the Boolean'd edges. Is there some way in Houdini (SOP or OTL) to cleanly rebuild a mesh from scratch (based on an existing mesh) and clean it up for 3D printing? For example, turn it into a point cloud, then I, as a human, could provide the software with clues where "inside" and "outside" is (e.g. by creating points and defining them as "inside" and "outside" the model. The SOP or OTL would then rebuild all polys in a way that creates a consistent, clean mesh. I tried the PolyDoctor SOP and turned most of its "Repair" options on, but it didn't do anything useful.

Hi everyone, I am trying to find an automated way to clean up some CAD geometry that I have. Retopo is no problem, the only issue I have is that the model has a lot of interior geometry that I want to get rid of. Interior and extrerior are connected !!! So I was trying different things without getting a decent result. I am thinking that one should send out a ray along the normal and see what it hits. Ideally multiple rays at varied angles to be sure. Outside points should hit pretty much nothing. So how do I do that? I dont know if a gather loop is a good option. Anyway, I could bot get that to work on sop level. Any help with this would be truly great. Thank you very much in advance.
