3D Warehouse - Square One

What is the best way to rescale objects in 3D warehouse.

Can you turn models on and off in the model? Can model be on a specific layer?

I use 3DW, and I'm gonna upload my models too.

Thank's for this one.

Need help,whenever i click on the download button it doesn't do anything

Excellent review of 3d Warehouse. Trimble has recently added a lock so you can not go directly to 3D warehouse or download models from 3D warehouse if you use the link in Sketchup make 2017. In addition, a filter is missing so you cant search for models compatible with a particular version of Sketchup.
Off Topic: I think this is pure theft, as I assume a lot of the models that can be downloaded, are uploaded by users who have made them available for free. Now only users who pay for Sketchup or users of the very basic free web based version can download files. In general, I think it all got too commercial after Trimble took over the program. But that's another discussion.
I generally like your excellent videos very much. Thanks!

I wonder why Ikea don't upload models? Looking at their documentation they must have 3D files, and I'm sure that being able to directly use official models to do some SU design work would increase their sales.

Is it possible to make models that are interactive that users can go through?

You're such a good teacher. Do you teach other subjects as well, like programming or similar.
