Hi there,
This is my first post here and I'm quite new to autolisp programming.
My problem is that I want to automatically generate a 3D Polyline across existing 3D Polylines (please see IMAGE 1 below). is this possible through Autolisp as this has been puzzling me for some time now. (Cyan line is ar z=0, yellow is 3D polyline crossing contours and grey are 3d contours comprised of 3D polylines)
I'm aware this process can be done manually using the apparent intersection objectsnap in plan view or by using civil 3D. However I am simply looking to speed up workflow as sections like these take up a lot of time when there are many of them to do and I don not have access to Civil 3D, only standart AutoCAD.
Any help with this would be greatly appreciated!
if there is any further information you need please let me know.
