Rotating Objects - Three Angle - Procedures

The Rotate Object - Three Angles command allows the user to apply three rotational angles to any objects selected, in the following order: Orient, Tilt and Roll.

Rotation angles are applied relative to the object coordinate system (OCS). The object orientation angle must be specified and it becomes the X-axis in the OCS.

  1. From the Modify menu select Object-Rotate-Three Angle, or from the Rooms/Objects toolbar select the image\objectbtn-rotate.jpg. Left click on the pull-down arrow to the right of the button to invoke the secondary menu.
  2. Select the object or objects (window selection) to  be rotated 9Single, Window or All).
  3. Select the 1st point on the local X axis (this axis defines the local X axis of the Object Coordinate system).
  4. Select the 2nd point on the local X axis.
  5. Select the point to rotate about (the base point).
  6. 1st Rotation angle (Orient) – Local X axis rotates horizontally; Rotation is applied about the Z-axis.
  7. 2nd Rotation angle (Tilt) – Local X axis rotates vertically; Rotation is applied about the OCS Y-axis.
  8. 3rd Rotation angle (Roll) – Local Y axis rotates vertically;Rotation is applied about the OCS X-axis.
