LT 2024 supports Lisp with limitations, yes it can bite you at times with some stuff missing.

LT 23 has some LISPs or is it LT24 where they started using them, in which case you could try: http://lee-mac.com/upgradedburst.html, however this was written for full CAD and not the limited LISP that LT has now

Just put under line : (cons 1 (itoa (setq i (1+ i)))) (cons 62 256)

Ignoring the radius thing highlighted above (assume this was just a quick sketch and you'd not set the inner radius differently) I assume that these are 2 segment rebars though the codes should work for many bends? Fillet the polyline segments with radius r (r being the outer radius?) Offset inwards by thickness t (the radius will now be (r - t) ) Join the ends together as one polyline Let us know if the drawn lines ('single lines') are the outside edge, inner edge or centre of the rebar and if the radius is the inner as on the sketch. Also are there defaults for the radius and thickness that can be preset into the LISP... and then it should be fairly easy to make up.
