SW 2018 STL export runs very slow.

I was posting in the forums here to see if anyone else had this issue before going back to my VAR. Most of the time I can find a fix here.

Just for history, I have clean re-installed 2018 twice for other issues.

I don't know what it's doing for 28 minutes @ 25% CPU (100% - 1 core), but there is actually no disk access to write the file until the last few seconds when it finally does write the file.

Update on slow STL performance:

After working with my VAR he is able to duplicate the slow write times for STL's that have very fine resolution (Were talking 1 degree and .001" tolerance) and approach triangle counts of 4+ million and file sizes of 200Mb+.  That may be a bit confusing but we don't know exactly what triggers it.  Of coarse files with organic curved shapes will create high triangle counts, and that's where I ran into the problem.  To sum up, this has been passed onto SolidWorks as an SPR to be resolved and likely show up in a service pack.

Hope this helps answer folks questions - I'll post any pertinent updates.

The SPR has not been assigned yet. I'll post when it gets assigned.

It's a 2017 file and the export settings used are:

STL,

1.0 Degrees, 0.0007 Tolerance

That should produce about 4.5M triangles.

I can't attach the file as it's 30Mb. So here is a link to it:

Hello everyone, Here is the response:

I have attached this SR to SPR 1072372 (Performance: SOLIDWORKS take a very long time to save file in STL when using SW2018).
This is definitely a regression in SW2018. SOLIDWORKS R&D did a lot of changes in the code on how we handle STL files due a new feature introduced in SW2018 release (graphic bodies). I believe this will be a priority SPR for them. I will bump the priority of the SR to high as the performance is not very good with this settings.

Paul,  Even with the errors 2016 & 2017 exports in 12 seconds versus 5 Min, 57 Seconds  for 2018 (On the same machine). That's the real issue.
