SketchUp Hangs for 30 seconds every few minutes

varies. this one is local. the file is about 260 MB

It isn’t a good idea to save files directly to the cloud. Better to save locally and then sync the file in DropBox or wherever you are saving them.

A 260 Mb file could take a little time to save during Autosave. Have you tried turning off Autosave in Preferences?

yeah, generally, I will do all of the major work locally unless I am collaborating with someone. I haven’t tried turning autosave off, just changing the length of time. I will try turning it off. Thanks.

Even if you are collaborating with someone else, you should save locally and sync the file in the cloud.

Good luck.

I agree with your work stream re saving locally. Sometimes I am just lazy, and that’s not the problem here :). SO, I turned off autosave and it seems to have worked! I had changed the interval to every 20 minutes and it was still having about every five, so I assumed that wasn’t the issue. Curious! It seems to be fixed. Thanks for your help!

What version of SketchUp is issue this about ?
(Your forum profile does not give a SketchUp version.)

Hi Dan,

I think I got it solved, but thanks so much for responding!

I’ve been involved in helping another forum user developing a massive model - about the same file size as yours. Even a manual save takes up to a minute, with the spinning ‘wait’ beach ball for that time, and a frozen model.

AutoSave was probably doing the same when you had it turned on (though even when I was using AutoSave with his large model, it didn’t often freeze on me.)

Perhaps! Even though the beachball timing didn’t correspond with the
autosave interval, turning off autosave has solved the problem. Now I just
have to remember to keep saving since I am prone to bugsplats with my big
models. Thanks for your help.

Suppressing the symptoms of a problem doesn’t solve the problem.
It merely enables you to get stuck in deeper mud.

Turning off Auto-Save won’t stop the bugsplats, while the risk of losing more time and effort increases.

Modeling technique has a tremendous impact upon model performance.
Learning how will make modeling far more enjoyable and productive.

Auto-Save is a known issue that’s been around for many mac versions of SU…

turning it and Create Backup off is common amongst mac users…

closing Outliner, Components Browser and Color palette also greatly reduce the likelihood of splats…

Disabling any extensions that use observers to log model changes is advisable as well i.e. vRay, DC, ACT…


Thanks for this! I appreciate you taking the time to respond.

I do all of those things, although sometimes, I get sloppy! I buildup from
basic geometry, too. Unfortunately, I model highly complex sets for
theatre, so this kind of thing may just be the price of doing business
right now! I also use a lot of things from the warehouse, so sometimes
things are a bit out of my control.

I didn’t know about the materials browser. I generally leave that open all
of the time. I will try that! Thanks for your response.

It doesn’t have to be the price of doing business. You can learn good modeling techniques and create clean, easy to work with models. Doing so will improve your efficiency as you model and make edits and reduce the time you have invested in the model.

You can keep control of the modeling by importing assets from the Warehouse into a file separate from your main model. Examine the component and make any modifications you need before copying it into the main model. If you copy only what you need into your main file, you’ll keep better control over file size and things like bad geometry.

My point is that we all pay the price for getting sloppy and making mistakes. I was attempting to be lighthearted about those mistakes.

You should also purge your model often to get rid of the warehouse components you have imported and since discarded. They might be a big bloat to your file size.

If there are a lot of hi-poly 3dwarehouse models you want to keep, see this thread for some ways of simlifying them:
