12.Axis and Arrow Keys

Sometimes when you are trying to move something or drawing a line it becomes hard to get it to do so in the direction you want. Sketchup has one unique way of ensuring that you lock the axis you want to work in. Up arrow is blue axis the right arrow is red axis and the left arrow is the green axis. By tapping them when you are doing something locks it to that axis.

If you tapped the wrong arrow you can re-tap it to free the object or tap the arrow you were supposed to tap. You can also lock an axis by using the Shift key while aligned to an axis.
