Hi Michael T, thanks for sending the file.

I tested exporting your file in both the Dec-19 and Feb-21 MoI releases, and the weird thing is that the generated STEP file is virtually identical between them.

There only seem to be 6 lines that are different between the STEP files, and those are all just for timestamp entries and nothing relating to actual geometry.

So that's pretty strange that you're getting different results between them when they seem to have the same geometry in them.

Can you possibly send me the different STEP files themselves that you generated from each beta version so I can see exactly what you are getting?

Thanks Michael G. They are off to you.

Let me know what you think.

Hi Michael T, thanks for sending those files.

But yup your exported files are virtually identical as well.

The only thing other than time stamps that is different is just a label stating which version of the export library was being used.


I used the WinDiff utility to compare the files, these are the only lines that are different between them:


(line 4 in dec beta)
FILE_NAME ('C:\\Users\\Michael Tuttle\\Downloads\\12020827-MoI\\DECbeta-STEP.stp', '2010-02-27T14:39:08', ('Unknown'), ('Unknown'), 'HarmonyWare STEP v1.4.2', 'HarmonyWare Translators', '');

(line 4 in feb beta)
FILE_NAME ('C:\\Users\\Michael Tuttle\\Downloads\\12020827-MoI\\FEBbeta-STEP.stp', '2010-02-27T14:40:38', ('Unknown'), ('Unknown'), 'HarmonyWare STEP v1.4.3', 'HarmonyWare Translators', '');


Then 5 lines that are just purely time stamps that look like this:

(line 11612 in dec beta)
#94190 = LOCAL_TIME (14, 39, 8., #94180);

(line 11612 in feb beta)
#94190 = LOCAL_TIME (14, 40, 38., #94180);


And of course, since those contain the current time at writing the file, it is normal that those should be different between exports even from the same beta.


I’m amazed that there would be any difference importing these files into NX4, since there is no difference with anything relating to geometry between them.


I don’t really see what could be causing a difference between these files, unless for some reason NX4 tries to look at the version number of the STEP library that I’m using…

Hi Michael G.

I've tried a few more STEP files out of MoI FEB beta into UG NX4 and everything was fine. solid bodies, not sheet bodies. I can't seem to reproduce my original issue.

Maybe it was lunar alignment! :-)

I will keep you posted if I run in to it again.

Thanks as always,

Michael T.

Hi Michael T - that's mysterious but I'm glad it is not a persisting issue!
