Rotating in 3D Space

The Rotate3D command rotates drawing entities in 3D space.

You can rotate entities about a specified point at a specified rotation angle on a 2D plane using the Rotate command. If you want to rotate entities in 3D space, use the Rotate3D command where you specify an axis of rotation and an angle of rotation about this axis.

  The "Right-Hand Rule" helps to explain the rotation around the axis for the command. In this rule, the axis of rotation is shown as the arrow gripped by the right hand, where the direction of the thumb points from P1 to to P2. Rotation, from the start or existing point, is indicated by the fingers on the hand (counter-clockwise when viewed along the axis from the P2 position).

To rotate entities in 3D space:

  1. Type Rotate3D at the command prompt.
  2. In the graphics area, select entities to rotate and press Enter.
  3. Click in the graphics area or type 3D coordinates to set the points on the axis (axis of rotation), or specify an option:
  4. Define the angle of rotation:

    Click in the graphics area to specify the first and second points.

    - or -

    Type 3D coordinates for the first and second points.

    - or -

    Specify the Reference option, then type a reference angle and new angle, or click in the graphics area to specify a reference angle and second point, and a new angle and second point. The difference between the reference angle and the new angle is the resulting rotation angle.

      A positive angle rotates counter-clockwise around the axis. A negative angle rotates clockwise.
