Earning with SketchUp on youtube?

How with that thing? May I use SketchUp Make 2014 to earn money on youtube videos or it is illegal? Because In Google SketchUp 8 I thought that I can earn money. Reply me please.

We are no lawyers here on the forum, but the consensus is that if you earn money in any way by using SketchUp it is considered commercial use and requires a Pro license.
