I am an Autodesk Certified Design Professional. I have been working on AutoCAD since 1993. I have expertise in developing LISP routines to automate process of drafting. I have used VBA extensively to generate automated BOQ from a drawing purpose. I specialize to automate the 2D drafting by use of LISP routines, constraints parameters and use of Dynamic Block. I also have worked with Block attributes to make drawing intelligent.
