How to export solid model? (by Altu Faltu)
This is a great software!

I want to export STEP file with solid model, which I cannot figure out how to do. Please help.

Export Surfaces option, as the name suggests, exports hollow parts. I mean only surfaces.

If I import it to any other 3D software, I cannot to join / cut or any other operations on it.

I need solid part be exported.

For example, I made a cube in solvespace, did Export Surface, imported in 123D Design and I see that it is hollow by deleting one of its faces. Refer attached image (orange cube).

That's how STEP files work: volumes are represented by the surfaces that bound them. There's probably something you can do in 123D to make it treat the imported file that way, but I don't know what.

I think there's stuff in the STEP file format that affects this too, so maybe there's a SolveSpace change that would create the behavior that you expect. That's just a hint to the importing program, though. The surfaces are identical either way.

I'm not so familiar with the formats, so can't comment much, but I did export a cube from 123d in STEP format and imported it again to find that it got imported as solid.

So, there must be something in STEP file format that dictates hollow vs solid.

I thought of asking 123d folks, but seems like 123D Design is going to get discontinued...
