None of those file types are solids. The closest that comes to it is IGES and it is simply surfaces and therefore contains no intelligence like hole/pocket/face features.

However, depending on your licensing there is a BREP loader for IGES that allows an IGES to to be imported in as a parasolid file. This still won't allow you to find features but it would be better than an IGES file.

Also, this BREP loader will clean/heal those messy IGES files.
