  • Horizontal: Forces the centerline horizontal. Ignored for 2PointCenterLines.
  • Aligned: Not available for FaceCenterLines. Forces the centerline to follow the general direction of the selected edges for 2LineCenterLines. Ignored for 2PointCenterLines.
• Shift Horizontal: Moves the centerline left or right of its normal position.
• Shift Vertical: Moves the centerline up or down from its normal position.
• Rotate: Rotates the centerline around its midpoint (degrees. + counterclockwise, - clockwise).
• Extend By: Makes the centerline longer by this amount.
• Color: The color of the centerline.
