Thank you Mark for the quick answer and for the information. The respective part of the Terms of Use already clarifies my above question in that I may freely use the model in this case.
For me the only question left is how to interpret 2.i. under "License Restrictions". There it reads:
You may not remove, obscure or alter any product identification, proprietary, copyright, trademark or other notices contained in the Model or accessed in conjunction with or through the Model;
In my case it is about this model of a mountain bike. The original looks like this:
…and I’d like to use it as a line drawing. For this I set the view in SketchUp to "View" -> "Face Style" -> "Hidden Line", which makes it look like this:
In this line drawing, you can’t see any of the stickers and decals with the brand names etc. anymore. However, I haven’t changed the model for this in any way, I only chose the above view mode.
This does not violate the above cited license restriction 2.i., right?
Thank you for having a look into this!
