Intersection

A point is constructed which is at the intersection of two primitives. The primitives can be chosen from STRA, ARC, or CIRC, although line-parts of more complex primitives can be identified by cursor. An ellipse (ELLI) is also an allowable primitive, but it is only possible to calculate the intersection point between an ellipse and a straight line. A qualifying point can also be specified when there is more than one point of intersection. See Endpoint Position for further information.

Examples

1. INT @

   The variation uses a single cursor hit to pick the intersection point explicitly.

   

2. INT BETW @ @

   Constructs a point at the intersection of two hit primitives:

   

3. INT BETW @ @

   In this case the second cursor hit acts as a qualifier:

   

4. INT /CIRC1 AND /STRA1 QUAL X100 Y100

   The intersection point is the one closest to (X100, Y100)

   

5. NEW STRA

6. FPT INT BETW PREV ARC AND PREV CIRC QUAL X200 Y300

7. TPT MIDP OF PREV STRA

   The STRA has one endpoint defined as that intersection between the specified arc and the specified circle which is the nearest to the qualifying point, the other endpoint being the midpoint of a specified line.
