To get the intersection of a line defined by four points using QuickCalc

  1. NoteThe QuickCalc Intersection of Two Lines Defined by Four Points button uses the ill(p1,p2,p3,p4) function.
    On the QuickCalc toolbar, click the Intersection of Two Lines Defined by Four Points button.

    QuickCalc temporarily closes and you are prompted to specify four points.

  2. Enter the coordinate values for the first point of line one, then the second point of line one. Next, enter the coordinate values for the first point of line two, then the second point of line two.

    QuickCalc opens and appends the value of the evaluated expression to the end of any value or expression already present in the Input box.
