I was working on a model in SketchUp and suddenly it went blank, when I reopened it, seems that the file is empty (I can’t even see the axes lines) but the file size is 200Mb. Can anybody help me? any suggestions?
I tried already:
Selecting all and copying pasting into a new file
Importing into a new file
Unhide all
…which resulted in a slight more than 51% file size reduction. You should get in the habit of making sure all edges and faces are untagged and that you purge unused stuff periodically.
Also make sure face orientation is correct throughout the model. There shouldn’t be any exposed blue back faces in your 3D objects such as the walls.
Like Dave, I had a look at your file. He’s got you sorted as far as revealing the hidden objects in your room.
But I don’t understand quite why the file size, even of the room alone, is so big - over 60MB with materials applied, and even deleting all the materials leaves just over 40MB in the file.
I had a look with Steve Baumgartner’s Statistics Probe. The cupboard with toy animals accounts for 140,000 edges, and the chair about 51,000.
Take care when importing models from the 3D warehouse (if that is where you got them from) to avoid over-detailed models - they will quickly slow down your modelling.
Check each imported model in a new file, and reject ones with either large edge counts (see Model Info/Statistics) or large file sizes.
If the material texture sizes are large, they too will bloat your file.
I suspect both have contributed to the excessive file size and edge count in your model for the level of detail you actually need.
As Dave said, there are still a lot of reversed faces in your model - it’s easier to see them if you view your model in View/Face Style/Monochrome.
