Make a clean sketchup file from existing file

[dbalex]

Is there a way to delete everything from a sketchup file while keeping all the scenes and thearender settings attached to those? I want to delete all my objects but when I do that sketchup hangs, even if I do it in small portions, it looks like I should select all objects and deleting them one by one, which would take ages as it's a huge file

What version of SketchUp are you using? On what operating system? Please complete your profile.

I don't know what the Thea Render settings are attached to but you ought to be able to erase the model. You could try purging unused stuff first.

You might need to check some of the render settings, I know from experience that deleting materials that have Twilight settings applied can cause issues with a model.
Twilight has a 'clean' option to resolve issues.

Ok I made some more tests, sketchup doesn't bug completely, it just takes ages too delete everything, I've let my computer run for a couple of hours and when I looked back it was deleted so I don't know how long it takes exactly.

I'm working on huge projects modelled in archicad and saved in sketchup. Sometimes I get an update from the file from the client and want to replace the exisiting model with the new one, in this file just deleting the old model takes forever so importing the new one is also a problem.

Remember that the "Not Responding" message doesn't mean that SketchUp has quit working. It means it's not going to respond to any further input until it's finished doing the last thing you told it to do. Purging unused stuff regularly should help reduce that. It should also help keep your file performing better.
