Sketchup "kindof" freezes after a while

I have been using Sketchup on my old MacBook M1 Pro 16GB, but i noticed that as my models grew bigger, eventually Sketchup would start to “freeze”, when trying to use Push/Pull, Move, or Scale-tools. Well, it didn’t actually freeze, but I would sometimes have to wait 30 seconds before i could actually use the selected tool. Nothing else “froze”, and I could interact with menues, or scroll the material list and so on… it was just the tool in question that didn’t start working after a number of seconds (5-30 in most cases).

I figured that this was a result of the model getting to large / required to much memory, so I just bought a new MacBook M4 Pro 48GB - but the same problem persists…

Has anyone else experienced this? What could be causing it?

Sketchup has a ‘budget’ of edges and faces it can handle, once you get over a certain amount things start to slow down. This is why circles, for example, are set at a default of 24 segments rather than 360 for 1 segment per degree to look ultra smooth. Many warehouse models are made using other software which uses many more segments or are poorly made and these can add a great deal of extra detail to your model. Also components that have been delete but not purge are still stored in the model space incase you want to use them, again increasing the drain on your hardware.
So if your models are getting large due to loads of 3d warehouse entourage you’ll get very little benefit from upgrading your hardware.

You could attach a model that you are finding lags and we can quickly tell you if it is the model or your hardware that is the problem and how to make things better.

Sure, here you go:

Nice model.
Nothing really stands out to me there as problematic.

Could it be something else causing an issue - which plugins do you have installed?
How often is auto-save set for?

Quantifier Pro and Profile Builder.

Have not changed any other settings at all, this is a completely fresh install (dont know what the default auto-save is set to)…

It behaves well for me, but a couple of comments.
Purging would be helpful.


Your pipework is very heavy.

And it wouldn’t hurt to edit the style and turn off profiles. They can slow things down a lot.
Not getting any lag, but I’m windows not Mac.

Try disabling those 2 extensions - save , restart and see if it does it afterwards.

Same here, in fact it was super fast in panning and zooming on my end. I agree on the cleaning up of some items.
Edit: Way too detailed

Yes, it’s really fast and smooth initially. And as long as I don’t edit anything it remains that way… but after ~30 mins of working, the phenomenon in question always appears…

I’ve purged, and turned off profiles, but to no avail…

Update:

With my new MacBook Pro M4, i noticed that this strange phenomenon disappears if I save the model…!

(But not on the old M1)
