Base.Axis class.\n An Axis defines a direction and a position (base) in 3D space.\n The following constructors are supported:\n Axis() Empty constructor.\n Axis(axis) Copy constructor. axis : Base.Axis\n Axis(base, direction) Define from a position and a direction. base : Base.Vector direction : Base.Vector Axis > copy() -> Base.Axis\n Returns a copy of this Axis. move(vector) -> None\n Move the axis base along the given vector.\n vector : Base.Vector\n Vector by which to move the axis. multiply(placement) -> Base.Axis\n Multiply this axis by a placement.\n placement : Base.Placement\n Placement by which to multiply the axis. reversed() -> Base.Axis\n Compute the reversed axis. This returns a new Base.Axis with the original direction reversed. Base position vector of the Axis. Direction vector of the Axis.
