create a solid by filling the space between two sheets

[gymbg]

Hi.
I have 2 cone trunk-shaped sheets, circular base, not concentric. is it possible to "fill" the blank area between the two sheets to get a solid?

In practice it is a mold in which concrete is casting. I have the dix of the mold, I should get the artifact that you create. Is there any command that fills me the 3d area of the mold?

I draw to explain myself better... .

create a plan on the edge of those surfaces, do a sketch projecting the 2 edges and extrude by activating the new solid option

I'm sorry, but I can't. I'm getting this situation... with the two floors and the two sketches.
now how do I extrude starting from one profile and coming to another? Since it is not a regular parallelepipedo?

I'm sorry, I didn't see the texture of the surfaces.
you can make 4 surfaces and then solidify everything.

Yes but the question is always that... how solid???? Oh sorry but I'm hard.... :

with the command merge surfaces

...in the end solved by making a sketch on every single floor in correspondence of each of the internal and external corners of my silhouette, then joined with the loft command of the 3d model card creating a positive extrusion for the external profile and a negative for the internal one...(to empty it)
