A client has sent me a 600mb STL. Ran out of memory when I tried to open it ( not a surprise) . Anyone have an idea how much ram I would need to open it. I have only 6g of ram now but am running a 64bit system so I can add more.
I made a 650MB stl and opened in it Rhino.
Memory peaked at about 3.4 GB
Note that I did not weld the mesh upon import.
When I imported with welding it peaked at about 5.2 GB.
So a solution could be to not weld the stl when importing.
Note that in Rhino an Unwelded mesh has a larger footprint so your file will be (a lot) bigger.
Also - be sure you’re launching the 64 bit version of Rhino. Rhino will always install both the 32 bit and 64 bit versions on a 64 bit system, so unless it says 64 bit on the icon, you’re on the 32 bit version.
If your system is 64 bit, you should have two icons to start Rhino - one will be labeled as 64 bit, the other, the 32 bit one, does not specify that. Do you see those?
