Hi, Indeed you can import a Samcef bank in NX CAE in order to create a fem & simulation file
Instead to speak about limitation, you can today load any mesh (nodes & elements) into nx and some material properties
Don't hesitate to test it and check in the documentation and ask us if you have another question
Moreover, all the properties that are not understandood by NX are stored in the Epilog text.
Note that the import dialog box allows you to tune the behavior of the import process.
