Axis by object Aligns the axis of rotation with an existing object. You can
select the following objects:
 Line: Aligns the axis with the selected line.
 Circle: Aligns with the 3D axis of the circle (perpendicular to the plane of
the circle and passing through the center of the circle).
 Arc: Aligns with the 3D axis of the arc (perpendicular to the plane of the
arc and passing through the center of the arc).
 Ellipse: Aligns with the 3D axis of the ellipse (perpendicular to the plane
of the ellipse and passing through the center of the ellipse).
 2D polyline: Aligns with the 3D axis formed by the polyline start points
and endpoints.
 3D polyline: Aligns with the 3D axis formed by the polyline start points
and endpoints.
 Spline: Aligns with the 3D axis formed by the spline's start points and
endpoints.
View Aligns the axis of rotation with the viewing direction of the current
viewport that passes through the selected point.
