John,

I am running SW2017 SP1.0.  I haven't had an occasion to try to open a NX file, so I went to grabcad and downloaded a NX10 model.  It came in as a blank screen with no errors showing.  I then downloaded a NX9 file and it opened fine.  I don't know if the file version made the difference or if it was just the way it was uploaded into grabcad.

I just downloaded another NX10 model, same thing, blank screen.  Beginning to think it may be a version thing.....I would investigate further if you are basing your decision whether to upgrade to SW2017 or not on the ability to do this....

Do a search in SolidWorks 2017 help for NX:

SOLIDWORKS 3D Interconnect

This functionality is currently available in SOLIDWORKS 2017 as Beta functionality. 3D Interconnect replaces SOLIDWORKS current translation capabilities with new technology and workflows for working with third-party native CAD data in SOLIDWORKS 2017.

You can perform the following:

• Insert proprietary CAD data directly into a SOLIDWORKS assembly without converting it to a SOLIDWORKS file.
• Open the proprietary 3D CAD format in the SOLIDWORKS software with its associative link to the original part.
• Update changes in the SOLIDWORKS file if you update the proprietary CAD data in its authoring application by maintaining all downstream features created in SOLIDWORKS.
• Break the link of the inserted part file with the original part file.

  The following formats and their versions are supported in 3D Interconnect:

• CATIA^® V5: .CATPart, .CATProduct for V5R8 – 5–6R2016

• Autodesk^® Inventor: .ipt for V6 – V2016, .iam for V11 – V2016

• PTC^®: .prt, .prt.*, .asm, .asm.* for Pro/ENGINEER^® 16 – Creo 3.0

• Solid Edge^®: .par, .asm, .psm for V18 – ST8

• NX™ software: .prt for UG 11 – NX 10

Hi John, in SolidWorks 2017, make sure you have the 3D Interconnect functionality enabled from your system options. See the attached screenshot.

Thanks
