Layout slowness: looking for possible causes

LayOut
1

LayOut has been quite slow lately. I am running Sketchup 2025 (25.0.633) on Mac OS Sequoia 15.2. The machine is a Mac Mini M4 24GB RAM.

This problem has been going on since I upgraded to 2025 but I am starting to think it is not due to it. Yesterday I was working on a LayOut file to which I sent a 130MB Sketchup file, consisting of a bookshelf with decorative objects on it.

Every time I tried to update the model reference or change the viewport from raster to hybrid LayOut would take minutes to do it. I am being literal here.

Today I started to think that the culprit was not the Sketchup file per se but something to do with some extension. In order to test it I removed all extensions and tested the same procedure without them. The result was that LayOut was fast in everything I tried to.

My question: would LayOut be affected by something like an extension conflict in Sketchup? Or could there be another reason I am not considering?

Thanks in advance for any help.

Hi, Edson -

I asked around, and no one knows of any reason that would help. Can you open Activity Monitor.app and see it there’s a memory leak in the extension, or if SU or LO are growing in memory size or cpu usage for any reason?

Hi Barry, I will do so as soon as I finish the tedious task of replacing my extensions one by one to see if they cause any conflict. By the way, do you know of any other way of checking for extensions conflict?

Nope. I binary tree them: test half, take the bad half, repeat.

Are you saying it does it if you send a file to layout and SketchUp is still open?

What if you import the SKP file directly into Layout without ever having opened SketchUp?

To tell you the truth I never worked in LayOut with the reference Sketchup file closed. Your suggestion is worth a try! Thanks.
