    That is how I interpret it. But it doesnt work. its not giving me the correct 1"

      var startPoint2D = worldToPlane(oplane, pt1);
      var endPoint2D = worldToPlane(oplane, pt2);
      var sketch1 = newSketchOnPlane(context, id + "sketch1", {
                    "sketchPlane" : oplane
                });

            skRectangle(sketch1, "rectangle1", {
                        "firstCorner" : startPoint2D,
                        "secondCorner" : endPoint2D
                    });
            skSolve(sketch1);
        var rect2 = vector(1 * inch, endPoint2D[1]);
    ....

          skRectangle(sketch2, "rectangle2", {
                        "firstCorner" : startPoint2D,
                        "secondCorner" : rect2
                    });

    dot() is builtin FS function which gives vector dot product (vector operation defined in linear algebra, for vectors a and b dot(a, b) = length(a) * length(b) * cos(a^b) where a^b is an angle between a and b)
