I need help welding lines on Draft site.
Need to make multiple lines, one
Found a tutorial on Youtube and I cannot seem to get it to work when I do it myself.

Help please

This is off the top of my head. If it doesn't work, let me know and I'll check from the office tomorrow:

select the lines

type "PE edit" in the command menu

Select J for join, press enter. Now you should have a poly line.

I am not sure if I am clicking the wrong button or what but it does not seem to want to work for me. I see all the commands in the window. Its a good possibility I am skipping a step or doing it incorrectly

Alex had it down pretty close, but what I do is select one line/segment and then type PEDIT. Y to confirm you're turning it into a poly line, then J to pull up the join command. Once that is done, select all the lines and arcs you want to join together, then press Y to confirm. X will exit the PEDIT command. Polylines will keep your wall scribe true, welding joins 2 lines into one straight line using the two outermost end points if I remember correctly.
