Well, 755,123MB is over 735 Gigabytes. If you truly have a 735GB cad model, I'm speechless. I don't even know of a desktop PC that would be able to handle a single file of that size.
If there is just something lost in translation and you have a 755MB cad model, I open 3-5 GB models in PC-DMIS on occasion without issue.. Major limitations are usually video ram and PC ram.
I thought I was misreading that at first. We deal with full engine assemblies that are 5-10 GB that don't have issues on PCDMIS or Calypso. I think we have 64 GB RAM and something like 16 GB video card memory on our machines
