circles and bolt hole circle segments. The required data is requested in
the message field.
Each hole can be moved to by traversing to display value zero. This
requires entry of the following data:
• Number of holes (maximum: 999)
• Circle center
• Circle radius
• Starting angle for first hole
• Angle step between the holes (only for circle segments)
• Hole depth
Example
