You’re good at getting entities, so you’re probably good at manipulating them as well. I’ll even include the often mis-understood MAPCAR function (so naturally, you know how to make an anonymous function with LAMBDA). Other iteration functions you know well should include REPEAT, FOREACH, and VLAX-FOR. Since you’re operating on multiple items in a selection set, you’re comfortable using the WHILE looping function. No doubt you’re pretty good with object selection, whether it’s a single entity using ENTSEL, or multiple items using SSGET (and of course you’re familiar with all the modes and filters it uses). What You Should Know by NowĪt this point, your left hand can probably type SETQ as easily as it can ASDF. No doubt you watch variables or maybe just use the Last Evaluation box. You’ve learned to load all or some of your code and can probably set Breakpoints and step through your code. You know what you’re doing…but you’re still somewhere in between and in a fuzzy intermediate zone.īy now, you’ve graduated from creating your routines in Notepad to the VLIDE (Visual Lisp Integrated Development Environment). Today’s post assumes you’re no longer a beginner, but not an expert yet either. In part one of our series, we talked about some of the basics you should know when beginning with AutoLISP and what kinds of things you can automate with that knowledge. Architecture, Engineering and Construction.Architecture, Engineering & Construction.
