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