"Arc"-like Leader

Recommended Posts

calafragilistic

When I used to use R14, I had a customized leader command where the first click was the endpoint of a leader (as usual), the second click was like the midpoint of an arc, and the third click was the other endpoint of an arc. You could continuously keep clicking and producing more arcs connected to the leader block, but typically I would just end the leader there, and it would not end with a text attached to it. Since I upgraded to AutoCAD 2010, the LISP function that I used for that did not transfer over, but I would like to have that again, as the spline leaders that are standard in 2010 look terrible compared to what I used to have, and are nowhere near as versatile. Is there a place I can find a LSP command to do the same thing, or will I have to rewrite the new command again? Here are some examples of how the finished 'CLeader' looked: untitled.jpg

Two arc leader lisp routines can be found here but they date from 1996/97. Who knows, maybe one of them will work with AutoCAD 2010. It's worth a shot.

I thought I'd give it a try, and the second one works in 2011.

Here's one I snagged on this site or TheSwamp.org - one of the two but can't remember. I love it and use it all the time. The size of the arrow head works off the DIMSCALE factor.

arc_dim.lsp

What command do you enter once you load it into autocad

If you are talking about arc_dim.lsp it would be "AA".
