Improve process to find Internal Volume

Improve process to find Internal Volume

The current functionality of Pro/E to find internal volume is abyssmal.  Users are forced to subtract parts and assemblies from a solid and find the resulting volume.  The process breaks down even further if the components themselves have internal volumes, such as tanks or tubes within a larger assembly.  For very large assemblies, the process does not work at all because of limitations of the shrinkwrap utility.

Please add a function to find the internal volume of a body using a more elegant solution, such as ray tracing with multiple light sources, acoustic waves, etc.

I would like to just add our POV on this which is we have to use expert CAd users to do this (the analysts who want that volume for a CFD analysis simply are too difficult to train!). We generally advocate a creation of a merged solid shrinkwrap which we then do a surface and boundary method surface copy to gather the internals. The catch of course is that Creo doesn't respect multi-boundary surface patches such as plane surfaces that have 'patches' inside and outside the solid. If that could be overcome we'd be almost there, then to circumvent the habit of users modelling parts that don't quite touch the algorithm could at least stop at boundaries where the gaps would be less than some distance (say fill the part with 1mm balls or something and th grab all surfaces that map to the inner). Perfection would be if you could then approximate that collection of geometry into a closed solid (a bit like how users would like the shrinkwrap feature to actually shrinkwrap the assembly to produce a simplified solid)
