do you have information which NX version and when will be compatible with SE2020 ?
NX 1888 is not able to open an SE 2020 par.
Error Message is :==================Could not open se2020.par
The following files could not be opened, causing this open to fail
se2020.par -Part file is from a newer version of NX than the one supported by NX
The Problem depends on the Parasolid Version behind.SE2020 uses Parasolid V32.0 and NX1888 uses Parasolid V31.1
So you will not been able to open this SE part in NX.
Solution is to install NX1899 (end of the Year) , this has also the Parasolid Version 32.0 behind.
