(ENTCNT1) axis
co-ordinates of
Centre
of circle.
Circular Bolt-Hole function (also
known as PCD) allows user to
generate a pattern of holes along
the perimeter of circle. After
taking data from user such as co-
ordinates
of
centre,
radius,
starting angle and number of
holes, the table of required points
is automatically generated and
user is shown distance required
to travel to each hole.
