Hey guys, I'm sketching an arm handle (I'm attaching the part) and I can't understand why my lines are undefined. I want my 2" line to be centered with the 11.5" line at the bottom. I sketched a construction line so I could center it, I had to draw the 2" a distance away from the construction line and then using move entities I moved it clicking the midpoint of the line and attaching it to the endpoint of the construction line. Is there a way that I can draw a line starting at the midpoint so when I draw the line it extends evenly to both sides? Thanks.
