8.1.9 ARC DISTANCE OFFSET
Offset point from the arc is calculated.
Input:
arc : start point, end point and radius ( R )
distance along arc from start point ( DI )
offset from the arc ( OD ) ( moving in the direction from start point to end point, right is
positive, left is negative )
Note: From start point to end point must be in the CLOCKWISE. If you calculate by arc of
COUNTERCLOCKWISE, change SP for EP and calcite changed DI manually.
Output: new offset point
