How to add vertex point quickly for a polyline by using referent line in AutoCAD?

Hi everyone,

Could you please help to guide how to add vertex point quickly to the polyline (1) by referent line (2), (3), (4), instead of add each point manually as picture blow:

Thank you so much,

I am using AutoCAD 2019.

There are many autolisp to break line or polyline,

example here, a line broke to hundreds pieces then use PEDIT to join and become a polyline

Hi there @tuanutc2

If I had the task, I would use a Lisp to Break selected Objects in AutoCAD (Break Intersecting Objects!) and then join them back to get the desired result.
You can also take a look at this post, maybe you will find an easier solution: Add Vertices to selected polyline at intersecting Lines

How are the reference lines located? Will the polyline always be constrained to a X-Y plane (no elevation change or slope)? Will there ever be intersecting line where you won't want a vertex added?

Here is a link to a short video demonstrating the use of an add-in to complete your task:
