From shape to solid

Hello!

Is there a possibility to make a one solid from several shapes which probably make closed object? The example picture is below:

I've tried "Stitch Surfaces", converting to surfaces, "Union Feature", "Unite Solids", "Create Region"... Nothing helped, maybe I was doing it not exacly how I should. What is more interesting - I managed to convert similar object via "Stitch". But it is only one exception. The rest of the buildings is not so easy. Any ideas? I would be very grateful if you could help me.

    Hi Piotrass,

    You could try using Extrude Mesh Volume. Here is an video example I made using roof surfaces and a foundation shape similar to those in your image. All items are extruded to the same elevation. This created a single mesh volume from the items extruded.

    Unfortunately - I have to make solid, not mesh. However - thanks for help.

    I think what is confusing it is the existing surface on level Dachy that appears to be coincident with the existing shapes on levels 40,41,42 and 45. If I only use those shapes the stitch surface works.

    Thank you for the patientce. Unfortunately, after doing this I get the stitch surface, not stitch solid (I've taken only 40,41,42 and 45). Do you get the same? I would like to have solid, not surface.

    It seems that this tool will create a solid if the shapes comprising the object form a 'water tight' object. If not then it will create a surface. I tested it on a simple set of shapes and that is the case. So there must be some gaps in your model. What is the source of the data?

    If you follow the method I suggested you end up with a "water tight" mesh volume. This can then be converted to a smart solid via Convert to Solid. You can also simplify the mesh first with the Cleanup Mesh tool.

    Thank you! Finally, Extrude Mesh Volume and Cleanup Mesh tool helped me.

    One more question: what do you advise me to do when I have two meshes with one shared wall (like terraced house) and I would like automatically (by selecting all of the objects) to convert them to solid? I Extrude Mesh Volume, but then I get one building instead of several buildings. Can I avoid this joining? You can see the example below:
