Chaining things up is frequent Hot Tip Harry contributor Jay Thomas with Chain Line (Tip #2165). This function draws chain links, as defined by a pair of blocks that are included in the download and must be located in the AutoCAD support folders. After loading the associated LISP code, type Chain to start the action. Jay set the defaults that work best for him, but you can change the code or select the options keyword to override his default settings. The settings include the scale size of the chain figures and whether to start with a face or edge in the link sequence. As you enter points, the chain lines are drawn automatically. For those wanting to know how to incorporate blocks into their line drawings, this is an excellent example from which to learn. Thanks again, Jay.
