Scaling in 3d warehouse

im using 1:1000 scaling, and every time I download anything in 3d warehouse nothing is coming out, i can’t seem to zoom enough if the component was really sent to my workspace, kindly help me is there a way to download the same scale i’m using?

It is best to download from the warehouse into a separate model space, check it, clean it, scale it if necessary and only then add it to your model.

Why are you doing that? Normally one works in SketchUp at 1:1.
