Over the last weeks the file for my model of houses has grown, due to numerous changes and experiments. Now, the response time for actions and the long time it takes to save changes is getting very burdensome.
I’ve tried to delete extraneous and no longer needed elements to no avail.
Is there a process, procedure, or tool that can remove all data not in the current model? I really don’t want to re-do everything and make a ‘fresh start.’
Any help will be gratefully appreciated.
