Hello!
I created an object with surfaces and can't modify it to a solid. Could anyone please suggest me how to do it? I created the surfaces as needed by the commands SURFNETWORK, Planesurf and loft. The white lines are sections.

Try to convert it to NURBS Surfaces, then UNION and then CONVTOSOLID. I had some (limited) success with this workflow on your model.

CONVTONURBS did not work: Command: _CONVTONURBS 5 found 5 not selected, not a valid object type.
Did I something wrong?

There are several LINES and SPLINES in your drawing - they were not converted, but the rest was. You can also delete them with QSELECT.
