Which versions of Solid Edge and NX have file compatibility?
Solution
As a general rule ST9 and NX11, ST10 and NX12 open each others files, however as can be found in the readme.html in the Solid Edge install folder, you can download the plmxml adapter to use the latest versions.
This is for 'file open', there might be other compatibilities (like Cam Express) where you have a direct function inside the CAD system.
From the readme.html:
Solid Edge, Femap, and NX plmxml
For Solid Edge ST9 file compatibility with the latest releases of NX and Femap, the latest plmxml adapter may be needed and are available after ST9 release at:
https://download.industrysoftware.automation.siemens.com/solid_edge/ST9/plmxml/ For NX, the adapter should be copied to the NX installation folder (%UGII_BASE_DIR%\UGII).
For Femap, it should be copied to the Femap\Util folder.
