BricsCAD’s LISP kicks sand in the face of AutoCAD’s

If you’re a power user or CAD Manager transitioning from AutoCAD to BricsCAD, one of the things you’ll like is that almost all of your LISP routines will just work. That’s not an statement that can be made about various Autodesk products that bear the AutoCAD name, such as AutoCAD 360, AutoCAD LT and AutoCAD for Mac. It’s not just simple old AutoLISP code that runs in BricsCAD, but complex dialog routines that use DCL, and Visual LISP stuff that uses ActiveX. Yes, even on the Mac and Linux platforms. Some DOSLib functions are built in and the rest can …

LISP programmers, have your say again

Autodesk wants your input again in its annual API survey. This used to be a closed survey for Autodesk Developer Network (ADN) members, but has been open to all for the last few years. If you do any AutoCAD-based development at all, I encourage you to take part. That includes those of us who do most of our development in LISP. Here’s the direct link to the survey. As you can see if you click the link, there’s a lot of stuff in there that assumes you’re keen to get developing for AutoCAD WS. If you’re not quite so filled …

AutoCAD 2013 – Help improved in one area

There’s one important area in which AutoCAD 2013’s Help shines when compared with its immediate predecessors. If you’re a Visual LISP user, you’ll be pleased to know that if you select a function name in the editor (e.g. (vla-get-ActiveDocument)) and hit Ctrl+F1, this now takes you to the appropriate page in the ActiveX and VBA Reference, as it should. In AutoCAD 2011 you just got a cryptic message or a 404 error, depending on the context. In AutoCAD 2012, you were just taken to the front page of Help and expected to find it yourself. Props to Autodesk for fixing …

The best feature ever added to AutoCAD is…

…LISP. I have now closed the What are the best features ever added to AutoCAD? poll, and the winner is AutoLISP/Visual LISP, by a long, long way. I don’t always agree with the majority view expressed in the polls here, but in this case I wholeheartedly agree. Adding LISP was the biggest and best thing that ever happened to AutoCAD. Autodesk owes an enormous debt of gratitude to John Walker for incorporating the work of David Betz, who was of course standing on the shoulders of John McCarthy. It’s a crying shame that Autodesk has been so terribly neglectful of …
