Set Maximise Viewport Slow to Maximise

Hello hello,

I’m using Rhino 7 for awhile now, but in recent times the Set Maximised Viewport command (assigned to F4 quick key) is taking too long to maximise. I first thought it was my keybord battery, but I have tested that and that’s not the case.

My mesh settings are not so heavy, so I think it has to be something else.
Maybe the graphics card settings?

I can paste my info file here, maybe someone can help.

Hi David -

When you start a new file from a factory-default template and don’t add objects, is MaxViewPort still slow?

New file seems to work fine at start up. Its seems to be a message “creating meshes” that is slowing it down. But what exactly in the mesh settings that is the cause? We have had rhino for the last 12 years, with modelling moulds in the same way, but recently a much slower response?

Thanks for the feedback, and help on this issue.


Hi David -

We’d need to see the file to be sure. If you can’t post it here, you can upload it - make sure to copy the URL to this discussion in the comments field.

Note that individual objects can have individual custom mesh settings - see the object’s Properties panel to check if that’s the case. If no objects have such overrides, you run ClearAllMeshes, and then set the Document Properties -> Mesh option to Jagged and faster, do you still have issues with that file? If so, you could try hiding objects to see if you can isolate a single object that is causing problems.

Okay. Thank you for the reply.
Its the model that is causing the slow down, but this behaviour is only recent. So I guess I can work by trial and error and see if I can isolate the problem in the future.

Kind regards
