When I am saving or performing a command, Sketchup will say, “not responding”. I think my file may be too big. It is 141 megs and I am still not finished. I booted up another drawing file that is only 20 megs and there is not problem. My drawing is a patio and I imported alot of objects from the 3D warehouse. I imported them directly into the drawing and made them groups. Most of the objects are people. Is my file too large and if so, how can I make it smaller?
Your system is sending you a message, “Unless you learn how to manage your model, you’re finished”
See this compendium of performance modeling techniques: How do I make SketchUp run faster? — SketchUp Sage Site
Best Practice:
Be mindful of what you bring into your model
Download components as separate files and have a look at them first.
Thanks for the education. I will do a much better job keeping the file at a realistic size. Thanks to people like you I will get pretty good at this and help others out in the future.
