Fusion impossibly slow with imported step file

[dlee_thesecond]

Hello everybody,

I uploaded the step files for a Nanuk 930 case because I need to print some pieces for it. I found the files here under "download documentation": https://www.nanuk.com/nanuk-930/

The file opens normally in Fusion but it's impossible to work with it. Everything is EXTREMELY slow. It's takes minutes to rotate the model. It could very well be that my laptop can't handle it. But it has a 960m graphics card and hasn't had a problem like this before. Is anyone willing to download the file and see how well it works for you?

Also, I've tried to open the graphics menu from the top right hand question mark menu set. But i click on the menu and nothing happens. That's probably unrelated but maybe not?

Thanks in advance!

I am assuming you are referring too the inner surface files for the top and bottom.

I only loaded the bottom down but that imported fine and is easy to work with on my 7 year old i7 iMac.

Thanks for taking the time to test it for me. Now I know it isn't a problem with the file. I'll continue testing and see if I can figure out what is going on.

Ok. I've solved the problem. In User Menu > Preferences > General, I changed the "Graphics Driver" to DirectX 11 or 9. Both are working fine. The auto-select option seems to have been causing some sort of issue.
