Slow file opening and purging

Hello SketchUp community

I’m an independent support technician, and one of my clients reported that a SketchUp file is very slow to open, work on, and purge.

Their desktop computer specs are:

  • AMD Ryzen 5 5600X
  • 32GB RAM 3200MHz
  • MSI GeForce RTX 3060 12GB
  • Kingston SA400S37480G

They are using Windows 11 Pro and SketchUp 24.

What do you think is causing the slowness? Do you think they should upgrade their computer?

They shared their file with me, and I’ve uploaded it to Proton Drive.

Why SketchUp 2024? Cr acked version?

The file is obese. Even the place you shared it from is having a hard time downloading it.

Without having seen the file yet, I expect there’s no hardware upgrade that would make a significant improvement in performance. Proper model management is important.

I’ll look at the file and see what I see. Back when I can get into it.

Standard cleanup procedure.

Fixed incorrect tag usage.


Purged unused content.

Purging is very slow due all the unused stuff that is getting purged.

Even after purging there are some excessively large textures. There’s no point in that since SketchUp downsamples them anyway. And there are some overly detailed components that could be simplified. The model is still sluggish but I’ll try some more stuff.

It seems there’s a yard sale going on with a lot of stuff just floating out in space around the model. If it’s not being used it should be deleted and purged as well.


The stuff can all be retrieved again if is actually is needed but there’s no point hoarding it in the model file. Removing all that stuff shown selected and then purging the file again made this reduction:

The file size has been reduced by about 78% so far.

No. Their computer is fine, but they should update to the latest SketchUp available to leverage big fixes and stability. And follow advice on keeping the model and resources clean.

Thank you very much for your help

nothing like purging roughly 5000 components and 1700 materials to loose some weight…
