Architecture, Engineering and ConstructionA series of Civil Engineering and Surveying add-on modules, also from DCA Engineering. After joining a CAD Forum we discovered Lee and felt that he was an ideal candidate to solve our problem with AutoLISP, so we approached him via his. Share this: Click to share on Facebook (Opens in new window)Earlier this year we decided to move to a new version, but we hit a problem in which most of the AutoLISP routines were written for R12, and so many of them would not migrate to a newer version.

But for example, after importing new Survey Figures to the drawing, if I use this LISP in a drawing that already contains countour lines as Polylines with elevations, they will be at 0.000 elevation in the end of routine. I use this LISP to convert Survey Figures (C3D) to Polylines (downloaded here from forum) and to bring them to elevation 0.00.
LISP stands for LISt Processing. What a Beginner Should KnowI think it’s important for any AutoLISP user to know what it is. Right now, we’ll start at the very beginning. It really doesn’t have to be, and even with just minimal knowledge, you can still accomplish a lot.This three-part series will help you become aware of the kinds of things you can do with AutoLISP at three levels of expertise: Beginner, Intermediate, and Advanced. You may not consider yourself a programmer, or it might just be intimidating. I just love AutoLISP, and I consider it my “home” language.But I also understand that my love of the language isn’t universal.
The functions that AutoLISP uses are called…FUNCTIONS—that’s easy! And FUNCTIONS sometimes require ARGUMENTS. In fact, the interpreter is built into AutoCAD, so you can run expressions right from the Command Line.As for basic Terminology and Syntax, you should know that items within a list are ATOMS. There’s no need to compile your code either. Others include STRINGS, REAL numbers, and INTEGERS.Note: One of the reasons AutoLISP is so easy for non-programmers (people like us) is that you don’t have to manage data types and memory allocation like other languages. AutoLISP considers a LIST or a CONS as a data type. You’ll need to know about them, whether they’re defined as a LIST, a CONS, a DOTTED PAIR, or an S-EXPRESSION (or just EXPRESSION for short).Of course, there are various data types you’ll need to be familiar with.
679 equates to the running osnaps I like. Make sure your OSNAP settings are always set the way you like them by using (setvar “OSMODE” 679). Which leads us to the next section… Ways a Beginner Can Use AutoLISP To Automate TasksWith just a basic level of AutoLISP knowledge, you should be able to do the following things.Control your AutoCAD environment.
Why not use your new AutoLISP knowledge to automate this sequence? You should have all the tools you need to write something like the following:(command “-purge” “a” “ ” “n”) (command “-purge” “r” “” “n”)Note: Two things from the above code. Get rid of unused REGAPPS, and also run Overkill. Purge and Audit, we tell you. With just a little AutoLISP knowledge a beginner should be able write their own custom ZE command:Do you find yourself using Move Previous often? Automate it!We’re always talking about keeping your drawings clean. But you still have to enter E to get Extents.
Below it, SS0 resets it to zero. SSA sets the SNAPANG variable based on a selected line. Just follow the prompts on the command line, and you’re on your way.The last two examples make new commands. Experiment…make or set your layers with -Layer. Lots of other commands do this. Also, the dash in front of the Purge and Overkill command calls suppresses the command’s dialog box and uses the command line version instead.

Final ThoughtsIn part two of our series, I’ll discuss some of the AutoLISP functionality you’ll need to know to become what I would call an Intermediate level, and what kinds of things you can do with those skills.And finally, to quote my original AutoLISP mentor from way back in the day, “until next time, keep on programmin’. Make your own Ribbon tab and panel or add it to an old-fashioned toolbar button for easy access. Notepad works fine.Finally, an AutoLISP beginner should know how to add their custom command to their menu. Also, don’t use MS Word, as it adds special formatting. Copy and paste is handy, but you have to be able to type them as well.
