Hello. I’ve been working on a school project for 2 weeks. I worked on it yesterday and everything was fine but when I tried to open it today, it keeps on crashing with those messages:
I think it’s because my file is 1GO. I am relatively new to Sketchup I don’t know how to clean it. Even if I wanted to clean it, now I can’t since I can’t open it.
Can someone help, please. I am desperate 
Upload the file to a DropBox or We Transfer and share the link to it. Maybe we can open it.
Thanks

It’s downloading now.
While that’s happening, by any chance do you use Time Machine on your Mac to do backups?
Nope but now I will definitely look into it. Thanks for the tip, I would have never thought of it
When things really go bad, it’s at least a safety net so you only loose an hour or two of work instead of days. It also helps to do Save As every once and a while to leave yourself a string of bread crumbs, as they say to go back to if need be.
I have the file open and I’ve gone through my standard cleanup procedure. First step is fixing incorrect tag usage.
I also purged unused stuff from your model.
I also checked for large texture images. There are plenty that are excessively large. You also have numerous needlessly hi-poly components such as this table.
Here’s the link to the file. Before you start adding more stuff to it you should go through and do more cleanup.
Thanks you so so much Dave. You basically saved my school year. The fact is I don’t even know how I chose hi-poly components. I don’t even know how to make lower poly objects. I am really new to Sketchup. I know I have “sketchup classes” next year so I can’t wait to know how to do more stuff 
polygon count is the second number. 1064 in this case.
if you make a cube, it’s 6 polygons.
if you make a cylindre based on a 24-sided circle, it’s 26 polygons.
you can make a whole house with a few hundred thousand polygons. then you’ll find models that are like 1million polygons for a table with a plant on it.
I expect it was mostly a case of not paying attention to the polygon count or file sizes of components you collected from the 3D Warehouse.
Best workflow is to be selective about the components you download to make sure they aren’t overly detailed. When you do download them, do so in a separate SketchUp file session so you can inspect them and ensure they are right for your needs.
This comes with some experience. Extensions like CleanUp3 and Skimp can help to reduce the poly counts.
Keep in mind that deleting components from the model space doesn’t remove them from the file. In your case it’s like you’ve been dragging furniture and other things home to see how the look and then deciding you don’t want them so you’re stuffing them up into the attic instead of returning them or donating them to someone else. Eventually you got so much junk up in the “attic” that virtually the ceiling collapsed on you.
Okay, I understand way better now
Thank you for your help and all your advices. Didn’t know the SU community was so kind and helpful
it’s the weekend, we return to being despicable on monday
btw, while you’re at it, in sketchup’s preferences, in general, make sure the option to purge upon save is on. it’ll prompt you to purge unnecessary stuff every time you hit the save button (what Dave did all at once)
you don’t always have to hit it, you can postpone your purge to - say - the end of the day. but at least it’ll spare you the 1gb monster file.
…except in the US, it’s a holiday - Memorial Day.
One more thing I should say: I do think I feel a performance hit in SketchUp whenever the system decides to do a back up (typically once an hour). That’s one possible downside to Time Machine.
Hi Marie I am just jumping in here. Check out SketchUp Essentials on YouTube, there is lots of free content. You might consider paying for the course, I took SketchUp in my Design Degree Program and have used it for years.
I signed up for the paid course and I learned stuff about lines that blew me out of the water Made my workflow so much better in just that first lesson. So much really good advice and information that my teachers did not know.
Not that this forum isn’t amazing, because it is everyone is super helpful, but I found the organized step by step, building on experience of the course kept me on track. It might help you avoid that panic when a school project has a temper tantrum.
