Hard crash when purging unused

Hello,

I’m trying to purge unused components and I ran into an issue I haven’t seen before. Normally, I purge unused and the model hangs, but it comes back after about 10 minutes of processing. This model hangs for 5 minutes, and SketchUp crashes hard (without even giving an error message).

Any idea what I could do?

Share the .skp file so we can see exactly what you’ve got and help you. Otherwise we’re just guessing which wastes everyone’s time.

The model is here. Let me know if you have issues downloading it.

Where have you been saving the file while you worked on it? Is it saved to to the cloud? I had no problem downloading it. I did my normal cleanup process. First I fixed incorrect tag usage.

Then I purged unused stuff without any crash. You win the Hoarder’s award for the month oof June. :crazy_face:

There are also a few ridiculously large textures which I resized to make them more reasonable.

See if this file works for you.

I worked on the file locally.

Yeah, I know. It is a Revit export thing. Revit export saves EVERY WALL as a separate component. There is another way to do that (when all walls come in as one unified component), but Revit exporter makes a mess of it and produces a model that is a lot harder to modify.

For the future, can you walk me through your cleanup process? What do you mean by incorrect tag usage? What extensions did you use?

The model works great, thank you!

Correct tag usage means that every edge and face is untagged. Only groups and components are given tags. Also, Untagged remains active at all times.

I used Default Tag Geometry from Sketchucation to fix the incorrect tag usage. For purging I used Purge All, again from Sketchucation. I use it instead of the Purge Unused button in Model Info>Statistics because it gives that report. You should be able to do the same thing with Purge Unused. And for material size, I used Material Resizer from the Extension Warehouse.

If you are going to be regularly working with imports from Revit I would suggest immediately cleaning up the model before you move on to adding any details.
