What is the nature of what's in the l1 variable? Would it be valid to simply run through the Polyline again and get an n3 value for each vertex and arc-segment midpoint to feed into the same
(chmark_draw l1 n1 n3 nil n2)
function?
Also, since this seems to be only about Polylines, do I assume correctly that by "arc" above you mean each Polyline arc segment, and not Arc entities? If so, just to clarify, you want all vertices marked and the midpoints of all arc segments, but not the midpoints of line segments?
Are these Polylines ever closed?
More answers to my questions are needed. The way I imagine doing this is going to require having the entity name of the Polyline, or its conversion to a VLA object, to get its parameters for stepping through its vertices. Is either of those what's in the l1 variable, or part of what's in it? If part of it, how is it contained there, so it can be pulled out?
Alternatively, post the definition of the (chainage_selectpline) function.

Search through your code resources to find something that includes:
(defun chainage_selectpline
and post that line and what follows it until you get to another line starting with (defun ... , or if you don't, until the end of the file.
