User's Manual
Point List Editor
Many screens contain a
which accesses the Select Point(s) screen that
allows you to enter a simple list of points or a
list of points that describe a line that can
contain curves.
Examples of how to enter different lists of
points are displayed in the lower portion of the
screen. Once the list is entered, tap
return to the previous screen.
Note: Spaces in point lists are ignored. They
are only used in the examples for clarity.
The examples for entering the three possible curve types are
explained in detail as follows:
•
7 ( 8 ) 9
The first example, defines a curve that passes through Points
7, 8 and 9, respectively.
•
7 ( 8, L ) 9
The second example defines a curve where Point 8 is the
radius point and the curve begins to the Left (from the point
of view of the radius point), turning from Point 7 to Point 9.
Note: When defining a curve with a radius point, the other two points
must be the same distance from the radius point for a solution.
•
7 ( 100, L, L ) 9
The third example describes a curve with a radius of 100,
using the same units as the job, that begins at Point 7,
turning to the Left (from the point of view of the radius point),
creating a Large arc (> 180°), and ending at Point 9.
