Minor bug: Rhino 6.30: overflow when exporting stl

exporting an admittedly silly sized size pile of meshes to an stl using the ‘file, export selected’ option. The result takes a while to load into memory and is reported to have a negative memory size!

Hi Patrick - You posted this in the Grasshopper category but as far as I can tell, this is exporting Rhino geometry in Rhino. Is that correct?
Can you please post a file that we can use to try and reproduce the issue with?
-wim

Apologies, yes. Pure rhino.

77Mb file that I had the issue with can’t be uploaded. It errors out at 14%

is Microsoft Shareable link to my company one drive ok?
