Lock an axis

5

When you are trying to plot a path in 3D space it can be easy to lose track of where you are in one or more directions. For a more precise input, try locking an axis,

so the point you are adjusting is constrained to just one direction. For example, if you want to push a point back in space, on the orbs page, just hit the Z button, which

will deactivate auto mode. Once you are happy with the location you can continue as before. It really is the best way to be accurate in your placements.
