Rhino Stalling when Using Mesh and vertices

Hello,
I am working on scanned data (mesh) of around 39Mb, Rhino runs nice and smooth for a short period then becomes slow and starts loading for short time and then becomes Okay again.
I have disabled autosave and put mesh settings to fast.

Hi - please post the result of the Rhino SystemInfo command.

What does that mean?

Hi Nassor - Thanks for that.

  • is the 39 MB file a 3dm file or is that the size of the imported file?
  • Can you attach a file?
  • I still don’t know what “[…] and starts loading for short time […]” means

When you only have mesh objects in your scene, changing the mesh settings won’t do anything.

Hello,
Sorry I cannot attach the file but it is an OBJ file from a 3d scan. What that means is it works fine for a short time then stops working or works really slow. When it stop working the mouse shows the loading(turning) wheel.

I hope that clarifies.

Thank you.

Hi,
Any Update?

Thanks.

Hi - without a file, it’s hard to try to reproduce things. Is it possible to share it with McNeel? If so, you can upload it on the following page - make sure to add the URL to this discussion in the comments field.
https://www.rhino3d.com/upload

Apart from that, have you tried running Rhino in safe mode to check if the issue persists?
-wim

Hi,
Yes I did try safe mode and there was no difference.
I have uploaded the file to the page you gave me. It is a much bigger file than the one before but I am also using another System that I believe is able to handle such a file. Here are the system specspc spec .txt (1.7 KB)

Thank you.

Hello - I see some problems opening your file as well - I don’t yet have a good idea what but Check does not like it at all so far.
Hm - well, it is 10 million vertices…

@nassor1738 - one thing to try is to SplitDisjointMesh - wait for that to happen (go get a coffee) and then go around and selectively rejoin parts or delete them, move to different layers, etc so that you can deal with a subset of the mesh at a time rather than all 10 million vertices.
