Can you convert an NX6 file to an NX4 file?

[aluminum2]

I am wondering if you can convert a newer version of a file so that an older system can read it. Other software that I use seems to be only compatible with nx4 file and not 6.

Check the FAQ. I dont think anything has changed since it was written.

Simple answer made complicated.

Open an NX6 file directly in NX4, NO.

Only want the solid geometry from NX6, Yes with work.
Export the NX6 model as a Parasolid export file inthe version of of Parasolid used ny NX4, then import that into NX4.

For associative solution you could do the following:
With NX open programming, access all the features in the file read their parameters, and write them into NX4, and thus build the part in NX4.
This is not a 100% solution for several reasons:
1. You cannot create feature that was introduced in NX5/6 in NX 4 e.g. The new holes, New Assembly constraints.
2. Due to changes in NX it is possible that a specific feature cannot be created although its type is supported – maybe due to bugs fixed in NX, or newer version of Parasolid.
3. It is possible that some features do not have API to read/write.
All these problems have some kind of programming solutions:
1. In some cases new holes can be mapped to old holes.
2. For unsupported feature, you can try to create geometry feature(non parameterized), and to add it somehow to the part without deleting parameters of other features, e.g. instead of 3 face blend introduced in NX7.5 you can create geometry equal to the geometry of the 3 face blend, and patch it to the body, without loosing history of other features.
As you can understand this solution is not simple, and requires a lot of effort, but it is feasible.
I hope this helped (at least in theory if not in practice ;-) ).
If you have any other questions regarding this solution you can contact me at: txl@transcendata.com.
