Q. Is there a way to move my geometry in the Z axis? All I get is the X and Y axis.
A. Yes there is.
First have your geometry on your screen that you want to move. Normally when using the Move command you just have the X and Y axis.
Before you implement the Move command, go to the Edit drop down menu, select the Auto2D/3D, select 3D.
Invoke the Move command, select the geometry you want to move.
You will then notice you have an option for the Z axis. Select your base points, select OK, then enter in the position you want to move your geometry to.
