Creating volume from the envelope of curved surfaces

Hi,

I'm trying to create a volume from a set of curved surfaces. I have 1 asymmetrical surface that is rotated three times 90 degrees and one additional symmetrical surface, so 5 total.

I want to obtain the envelope that encompasses all of these (as if you would do a drape in both Z directions and subtract them). Preferably in a way that I could keep on adding as much surfaces as I wanted.

Any help would be much appreciated!

Make a bottom surface for each one, 'Brep Join' to 'Closed Breps', then 'SUnion' them all together - one 'Closed Brep' result!

Here's a different way to close and join them:

Thanks again for all the effort. I'm trying to figure out what is exactly going on in both versions, so I can get to the point of having just an empty volume (like in the second version), but while maintaining the lower shells as my bottom boundaries. Now the bottom is being "filled" based on the square base which I'll have to change somehow. What I would like to accomplish is that the lower edges of the volume are defined by the lower bottoms of the intersecting shells. This definitely gets me closer to where I want to be though, so thanks a lot!
