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?

- Michael
