Convert 3D faces to 3D solid

I have a structure that is made up of 3D faces that I want to convert to a 3D solid. I've tried to convert it to a surface, then thicken it but when I use the convert to 3D solid it doesn't allow it. I've also checked through the forum but all the topics seems not to help me achieve this. The attached is a mine tunnel made up of 3D faces due to the complexity of its curvature. I could change it but all existing designs are like that but I'd like to be able to calculate volumes, which are easier using 3D solids than 3d faces

If all of your tunnels are as simple as your drawing, just multiply the end area by the length.

YOu can use the region command to convert 3dfaces to regions.  Surfsculpt can then be used to create a solid.  For your model surfsculpt could not find a watertight model so I added planar surfaces aligned with the ends and then successfuly used surfsculpt.

Just out of curiosity because I am using a really old AutoCAD version (R14) with no SURFSCULPT command, what was your volume calculation?

The root cause is apparently the ends do not align to the top.  Zoom in and there is a gap along much of the edges.

Is the "bottom" surface not level?

 

plines outer edge both ends and loft.   MaSSPROP Vol is 265.8948 cubic units

265 seems resonable as box containing the object would be 12x5x5 = 300 and the volue should be lest than that.

That worked. However, I used the patch function on each end, then surfsculpt to a 3d solid. The volume is 265.8996. Thanks alot
