coordinate system
—
You explicitly specify the rotation
angle about each of the original axis.

Points — You specify two points along the new xaxis and
yaxis, in a addition to the new origin, to define the coordinate
rotation.

Rotation in X / Y / Z

Type the rotation angle, in degrees, about each
of the original axis.

X / Y / Z coordinate of axis X / Y

Type the three coordinate values (with units)
of two points along the new xaxis and yaxis, in a addition to the new origin,
