SW2010 x64 seems to corrupt any ProE part I import. (it's 10 for 10) I found in other 3d packages that you can adjust the export/import surface tolerance. The idea is that if they match then the model imports without errors. Any ideas would be appreciated.
There isn't a tolerance on import, per se. What SolidWorks does is imports it exactly as it sees the data, and then you can run "import diagnostics" to close any gaps from the conversion. Ths import diagnostics is where you can set a tolerance.
When you say it "didn't import", exactly what does happen? What errors do you see, and how far does it go in the import process. It should automatically bring up the import diagnostics tool after the bodi(es) imports.
Also, there are settings for import, which you can get to by going to File>Open. Select "Pro/E" as the filetype, and then click the "Options..." button in the lower right corner. You will probably want to keep these all on default, the only one really worth changing is the "import multiple bodies as parts" option, as you see fit.
