Part: Shape from Mesh (Freezes)

[abasel]

When I try an convert this mesh to a shape my computer freezes (at about 20%). I have tried different computers, Linux and Window. I have tried cleaning up the Mesh using Blender and MeshLab.

Works with 0.19. But the model is not a single surface so cannot be directly converted to solid. It looks quite easy to recreate from scratch...

I tried 0.19 last night but this also froze from me. I got these to work a few weeks ago but now can't work out what I am doing differently.

If it can't be converted directly to a solid, what intemediate step am I missing?

Thanks for looking though. If it's working for you on 0.19 then there must be an issue on both of my system.

You first convert the mest to shell and then that shell to solid. But here there are actually 2 separate shells and so directli converting the resulting shell to solid fails.
Also this STL is quite small. I had to scale it by 2000 to get it to reasonable size around 79mm dia. Here is good aproximated recreation as Partdesign body:

When google, "converting to shell" takes me straight to converting to solid". It's probbly right in front of me but I can't find the "convert to shell" option.

Convert to shell is "Create shape from mesh".
