This is covered in their terms of service: "8.2 - For the avoidance of doubt, you may modify, distribute, and create derivative works of Content uploaded by other users in 3D Warehouse." and 11.1 (c) - "(c) By publicly posting or displaying the content you give other end users of the Services a perpetual, sublicensable, irrevocable, worldwide, royalty-free, and non-exclusive license to reproduce, adapt, modify, translate, publish, publicly perform, publicly display and distribute (subject to the restrictions set forth in Sections 11.4 and 20.3 of these Terms) any Content or derivative works thereof which you publicly post or display on or through the Services."

Apart from restrictions on aggregating models, anything people upload is free to use and fiddle with (as long as the person who uploaded it is the copyright holder).
