Too large file/part NX7.5 how to solve?

[kpkp]

Currently I'm working on a part which has become too large which makes NX very slow. The part is an edited copy of another part which has no issues. The eddited part is suposed a more simple version of the original part which I need for analysis. I did the following things:

1. Filling gaps and holes with the extrude function;
2. Making a lot of copies with the "move > copy original" function in one direction;
3. Unite on all copies;
4. Use the "move > copy original" function with 0 displacement to get 1 solid body feature;
5. Delete the history, but keeping the solid body.

The model itself should be fairly simple for NX. The face count etc. is much lower then the original file. The part file is about 80MB and the original file is in the 3MB range. I think that there might be some "hidden" history saved in the part, but I have no idea where. I allready tried to use the part cleanup with every option set, but this didn't help. The PC i'm working should be good enough (HP workstation Z400 with 16GB RAM and windows 7)

Can someone help me with this?

If these changes are not leveraging the parametrics of the original file, I would instead make a WAVE-linked copy of the original file, and then use Synchronous Tools to delete faces and such.

If you don't care about the parameters and just want a small file:

Try exporting a parasolid of the solid body of interest and importing it into a new file. The new file size should be much smaller.

Thanks for the suggestions. I'm not that familiar with WAVE-linked copies so I didn't use that option. I followed cowski's suggestion (export to parasolid and import that file). This works perfectly.
