I had sent this to sketchup and after a lot of convincing I was not looking for modeling strategies he tried the specific set of steps I suggested and was able to replicate it and "sent it up to engineering" I have not heard anything since.

I apologize I realized I forgot I had posted this. Yes I do run one plugin Maxwell render. We have also discovered we can avoid the problem if we purge materials and components only from those browsers rather than the "purge all" button in Model Info/ statistics.
I did send this to sketchup directly and they were able to recreate the problem, but I have not heard a response.

I did try that.. to no avail.

I have been having an issue where components on even small models become unbearably slow to enter and exit on even small models. Only 20-30mb models. Out of curiosity I tried it on a colleagues machine (who does not use sketchup) but with the exact same hardware... and it was speedy as ever. That got me to thinking about my user profile and logged on to a different profile on my machine and low and behold... speedy again. I thought maybe there were some temp files in my user profile causing it.. but I can not seem to find them as it is still slow on my profile. I have had another heavy sketchup user in my office try this with the same results... slow models become blazing fast opening and closing components in a new user profile.

Then we discovered that while in the new user profile.... that is working well.... If you purge your model.. you are back to painfully slow component entry and exit. Tested on several machines with the same results. Original slow model is zippy on new profile.. UNTIL PURGING the model.

thoughts????

I should add that I have much larger models not affected by this. I can not find the common denominator that causes this behavior

That worked great... thank you.

Sorry I am new to using the ruby script... just type that all into the command line?

Lion has a unique quirk of reopening the last file you had open in sketchup. This is particularly frustrating if you had a large model that has crashed as you can not open sketchup as it will just open and crash again. I have one file that every time I hit "close" it crashes (the file saves fine) But if I want to open another file I can't as it just crashes trying to open both files. Any workarounds? If I get it open I can quit the process, but was wondering if there was a way to stop the auto open last file.

This the issue I found in another post as "known Lion issues" the solution works IF you can get the file to close without crashing.

7. Models are now visible behind the Welcome dialog on startup and are remembered from session to session..

With Lion, SketchUp now remembers whatever models you had open in a previous SketchUp session and, on re-launch, opens those same models. This means that models can now show up behind the Welcome dialog, which is a change of behavior. It may also mean that SketchUp can take longer to launch and may potentially re-open a problem model from a previous session.

Workaround: close your models prior to exiting SketchUp if you do not like this behavior.
