This year, Autodesk is opening up this survey, which used to be confined to Autodesk Developer Network members. I approve. ADN represents a tiny (but important) minority of fee-paying developers approved by Autodesk. I expect the results will be rather different if a significant number of “normal” AutoCAD developers notice this survey and fill it in.
If you are, say, a LISP or VBA user and are feeling neglected, please go and have your say while you have the chance. The survey closes on 1 May.
