I am looking for an add-on that will give 2D parametric abilities to IntelliCAD. In my case, I am not interested in pre-packaged parametric shapes, such a Nuts & Bolts, or archetectrual package. Rather, I want to be able to edit the value of a dimension and have the object change shape automatically. While I am starting to create my own VBA program to accomplish my task, I would prefer to purchase a generic parametric utility. Since IntelliCAD is compatable with AutoCAD's Lisp, ADS, and VBA (the VBA model was recently updated), it is possible that any AutoCAD add- ons using these methods could be compatable. Any suggestions?
