Using Your Mouse
Modeling in SketchUp is easy to learn but can be hard to master. One of the most common tips SketchUp pros will offer to other users who are looking to up their SketchUp game is to learn how to use a 3-button scroll wheel mouse. Creating a model in SketchUp can be faster, more precise, and overall more efficient when you use the right mouse.
One of the biggest benefits of using the right mouse is that there are tools you don’t even need to activate to use, and can even use when other tools are activated.
For example, you can zoom in while the Push/Pull tool is activated to make sure you get the exact point you want to pull from.

Other great examples include:
Orbiting around an entity to find a partially hidden reference point.
Zooming out to use an inference point on out-of-frame geometry.
Quickly panning to another point of your model when making copies of an entity.
Tip : Another great way to level up your modeling is by using shortcuts. For more information on how to set them up, see Shortcuts .
