.prt file extn in NX

[sudhakarn]

Hi Folks,
Jumping into the question straight away.Why is it that the file extensions of all types of file is same in NX (.prt).In other software tools,the file extension is different for part,assembly and drawing files.How do i recognise each type of file here?
Request your support pls.

Searching this forum will give you plenty of threads regarding NX's .prt file reasoning.

Dates back to the beginning of UG time. There were no separate files for drawings, manufacturing, etc. Everything was a .prt and it has never changed.
Probably a lot of coding would be required to be updated to utilize file extensions for file types.
If using a PDM system, does it really even matter?

It's that way because that is how it started and still today you can go back to UG v9 (NOT NX9 - much earlier than that) and open files without need for any sort of translation or conversion. If it were to change, that bragging right would probably disappear. You recognize files by incorporating a good NX file naming standard such that you can look at the file name and know if it's 2D, 3D, ASM, etc. and the revision level - not really that difficult until you get into large assemblies but at that point PDM is probably the wiser route to go.

Because other systems want to make your life difficult.
You can add want you want to the end of the file name to identify it.

NX also gives you the option of doing the modeling, drafting, and machining, all in the same file, if you want.

Hi,
Thanks a lot for all the replies.This forum is extremely helpful for learning and sharing.

Whilst i do agree on all points mentioned,
there is a slight deviation.
The FEM side of NX has , since maybe 10 years back, used different file name extensions.
I do not know if there is a difference between a .fem or a .sim and a .prt, but still, the extension differs.

Yes, these files are different. While a prt file can hold modeling, drafting, and/or assembly information it cannot hold FEA information (meshes, loads, constraints, etc).
