Hi All,

I am having two point lists ptlist1 and ptlist2. Now i want to find the intersections among the points in ptlist1 & ptlist2. Please let me know how can i do this.

Thanks,

Kumar.

Thanks Lee!

I think you can draw a poline from the first list and another polyline with the second list and use the vla-interesectwith function for intersections points

Consider the inters function

Thanks for all
