You don't have to draw an XLINE to find the intersection to the original lines. The inters function can actually accept an optional 5th argument: (inters p1 p2 p3 p4 [mode]). If you supply an argument to it (be it nil or any value), inters will find an intersection point assuming that the line formed by p1-p2 and p3-p4 is extended infinitely.
(inters
'(0 1 0) '(0 2 0)
'(1 0 0) '(2 0 0)
nil
)
I have shared a Dynamic Block and you can download through the link below and also can watch video that demonstrate it how to use 2D dynamic block to develop a flat pattern of a cone that has been oblique Section.
I hope you will subscribe and Like my video/channel.
Thanks
