Model slow to save

[tspco]

I have one particular model that takes way longer to save than most of the others, and some of the others are far more complex.
Is there a way (plugin) to identify what the issue is, and then allow me to correct it?

go to "Window > Model Info > Statistics > Whole Model" and hit "Purge Unused" to get rid of the unused stuff as materials or component definitions etc.

You could also use TTs CleanUp plugin which gives you more information what is done during the cleaning.

If nothing helps, unhide everything, switch on all layers/tags, select verything and copy to a new document.
