Hard crashing with meshes

Hi. I have a good workstation with 32G Ram and continually have total computer lockups when selecting meshes, especially when switching to another program and then coming back to Rhino. Granted these are large complex meshes, but it is extremely troublesome. Is there a way to allocate memory to Rhino so this won’t happen, or at least it doesn’t require a computer reboot to recover?

Impossible to guess with so little information.

  1. Run the Rhino SystemInfo command and reply with the results.
  2. See if the file has any bad objects in it using the SelBadObjects command.

Also, there are no doubt bad objects imported - meshmixer - so fix those first?

You are running on a computer that is grossly inadequate for running Rhino.
This is mostly due to the inadequate Intel GPU.
Making it worse is your driver is archaic.

If I were you, I would do 2 things:

  1. Update the GPU driver: Search - Intel.com

  2. Unplug the second monitor as you do not have enough display resource to run 1 monitor let alone 2.

  3. Since it is a desktop, you may be able to add a good GPU like an NVIDIA RTX with as much VRAM and CUDA cores as you can afford.

  4. Or buy a computer that will run Rhino well: If you are buying a new laptop READ THIS

Any luck?

So, 4 G of vram, that’s what causing this? I guess I’ll get a new video card. I’ll try the driver too. Thanks for the help.

No. You’re reading that incorrectly.
A minimum of 4 GB VRAM for each standard resolution monitor.
You have 2 monitors so 8 is the minimum. More is recommended.
Pick a card with lots of CUDA cores for speeding up GPU based rendering.

Gotcha, will do.
