3D Transform Controls

Transform Mode

Drag on 3D view to rotate. Shift+drag = roll.

Coordinate System

Global: world axes. Local: follows stand orientation. Face: along stand slope face.

Move Along Axis (feet)

Axis lock:

Move amount (ft)

X=East/West, Y=North/South, Z=Up/Down. In Face mode: X=along width, Y=along slope, Z=normal to slope.
