If you would like to upload models to 3D Warehouse, you must have a Google Account. Your Google Account login information is the same as your login for any Google product, such as Gmail or Google Docs. If you don't currently have a Google Account, you can create one on Google's New Accounts page. Note that you don't have to have a Gmail email address to create a Google Account – simply click
I prefer to use my current email address on the New Accounts page to create a Google Account using a different email address that you prefer.
Once you've created a Google Account, you simply use that account information to log in to 3D Warehouse. After you've logged in, you can start Uploading your SketchUp models.
