color of polyline inside a dynamic block

[rog1n]

Hello, is possible to get the color of a polyline inside a dynamic block? I want to click at the end of a polyline inside a block and draw a polyline with the same color like the example below.

Sure:

(if (setq e (car (nentsel)))
  (alert (itoa (cdr (assoc 62 (entget e)))))
)

I use nentsel to pick an attribute you want to change, you can get properties like att tagname, textstring, a little extra code and can get block name. Handy for global change an attribute in multiple blocks.
