(2) Automatic calculation of linear-arc intersection
When it is difficult to find the intersections of a given line and circular arc, the intersections are
automatically calculated by programming the following blocks.
Example
(3) Automatic calculation of arc-linear intersection
When it is difficult to find the intersections of a given circular arc and line, the intersections are
automatically calculated by programming the following blocks.
Example

:
I and K Incremental position from arc end point
:
P and Q Arc center position (absolute position)
:
H = 0 Intersection with shorter line (B point)
:
H = 1 Intersection with longer line (B' point)
