how to add points on a polyline from vertex?

I have a drawing that have meny polylines were I need to put points on itwith differents  distances from vertex, becouse these polylines represent the road and the points represent the interferences along it.

What version of AutoCAD are you using?

From what I understand, you want to change your polyline by adding more vertex to it.

When you click on the polyline, it should be highlighted with blue squares (vertex points). When you mouseover one of the squares, a menu should open with the option to "Add vertex".

Alternately, you can select the polyline, right click on it to open the right-click menu, go to Polyline and select "Edit Polyline". A new menu should open, where you can click "Edit vertex", then simply click "Next" or hit Enter until you land on the Vertex that you want to edit.

Hi @Anonymous  it can be do by lisp , just draw point at such place over the polyline , and then it can be add as vertex to the poly . 

Please upload a sample.dwg with polys and points .

I will be glad to help you.

The previous Replies assume you want to add vertices.  Is that correct, or do you want to add POINT objects?  In what form do you have the "different distances"?

I need to put points, don't vertices. Thanks 🙂

A small sample drawing showing the nature of the Polylines, and whatever form you have the "different distances" in [a spreadsheet file, perhaps?], and a description of how they relate to the vertices [one Point downstream from every vertex, or whatever the criteria are] would be a start.

One way is to add a circle centered at the reference vertex with a radius equal to the distance to the point.  Then use object snap intersection to place the point.  This process could be streamlined with a vlisp program.

... assuming the Polyline is made of only line segments.  On an arc segment, the distance along the curve of the segment will be longer than the desired distance, if that is the radius of the Circle.

Yes, of course.  I didn't give this question sufficient thought. Using a circle will also fail if there are vertices closer than the specified distance.  More information from the OP is needed about whether arcs may be encountered and if the distance is to be measure along a single polyline.

I need to put point on the polyline, and the polyline is not straight. I've been doing it using "mesure" but I need to exclude the succeeding points after the first poni that is the point that I want. Attached is a piace of my drowing to you to undertand. The vertice were I need to start count to put the point is on the arrow. My version is 2018. Thanks to all.

@Anonymous For better understanding, and maybe get further help, please upload such sample.dwg
As far as I know, ACAD only can edit DWG., and the file where you have point's data.

If it's always from the end, not from just any vertex along the way, you can use FromEnd.lsp, with its (fe) pseudo-Osnap mode, available >here<.  See the usage instruction at the linked Message.
