If your goal were to:
modify (defeature, remove blends, convert solid==>sheet bodies, hide unnecessary complexities) an assembly of .prts for ANSYS meshing it is much more convenient to
1) modify each part singly
2) import it FROM ANSYS (on top of previous parts)
3) create a component with a name
4) hide it in ANSYS with the others
5) leave behind solids which will be modeled as shells, bars, masses, ....
6) mesh each component (transferred .prt) separately
7) connect as/where necessary
which doesn't work, because the parts were created with part-significant coordinate systems and mated in shifted, rotated positions (which COULD have been done as translations, etc BEFORE assembly) and the process above brings them all in as if the Absolute CS's were the same.
Mating creates an orientation which must be replicated by translations, rotations before suppressing = deleting the mates in the assembly.
The alternative is the much slower, messier process of importing/exporting the parts as an assembly, (now undifferentiated parts). This preserves the orientations of the mates as long as the surfaces... are still there. The parts arrive at the ANSYS end as a semiconnected and unidentified set of volumes (not if sheet bodies), areas, lines, and points. For the meshing to make sense, the stuff must be re-assembled into components manually.
You can't take out the mates without re-positioning & re-orienting each mated part to the common ACS.
Having the mates prevents individual part export/import.
Big,Big difference in prep and meshing time.
