I wanted to upload a sketchup file but it was to big, I had only a small playground house (which I made in the first course on this site) and I took 3 cars from 3dwarehouse. So I thought I delete one 2 cars but the file didn’t get any smaller at all. How is this possible? Is it because the car I deleted is still there in the file somewhere? If so how do I totally delete it?
Components, materials, layers/tags etc can be purged individually from the model in their trays, or all together in Window/Model Info/Statistics/ Purge Unused.
And Box should add, just because you deleted them from your model, they are still hanging out in the components tray.
