top or collect selections of lines

[libra86]

Good morning.

I'm wondering if you can create a macro, script or anything that can top or collect all the lines enclosed in a selection;
example: design a square, to collect or top the four edges usually select the lines of one edge at a time and then repeat the procedure for the remaining edges. what I would like and collect or top all four edges simultaneously with a unique selection.
Is it possible?

Thank you in advance.

if you draw the square with a polylinea you can collect in a single stroke all the edges with the option "polyline"

Okay, thank you, I actually tried and it works!
But if I had any random lines instead of the square?
I am able to create polylines but it would serve a macro that automatically selects the lines to become polylinee, then make the top or chord and finally "explode" everything to bring back the separate segment lines. . .
I'll do some tests and see what I can do. . .
