extrusion of a roof with different inclinations

[Andrearo]

Hi, I don't have a good knowledge of autocad 2019, and I find it unfailing, but I find myself having to solve this problem with a roof.
the main problem is the different inclination of each segment of the roof, which is being extruded one by one, intersect and create empty spaces, it is possible to create a solid whole figure somehow, or join the various extrusions?
reference building y house (steven holl).

problem solved with 3d polylines and loft command.
in the end most likely you will not get a solid but of the surfaces that closing them suitably will take the look of a solid

procedure:

I get the profile in 3d, using simple linesremove the profile with 3d polylinees simplifying geometry, then lift or lower the polylines of the appropriate thicknessI connect the different polylines using the loft command, obtaining 3 surfaces.complete with 3d faces and appropriate lower closureif you prefer you can do it exclusively with 3d faces
