Reply To: BasicGeometricCalc Intersect_​​circle_​​line bad results

Hi John,

The vector is not the endpoint of the vector, just the vector itself. So in your case if (0.5, 0) and (0.5, 1) are two points on the line, the vector is (0, 1).

BasicGeometricCalc can return the unit vector between two points:

call "BasicGeometricCalc" parameters iFunction = 1,
                                      Point1X = toX,   Point1Y = toY,   Point1Z = toZ,
                                      Point2X = fromX, Point2Y = fromY, Point2Z = fromZ,
                  returned_parameters Vx, Vy, Vz, distance

Vx, Vy, Vz will be the unit vector, and distance will be the distance between Point1 and Point2.
