Class Description: This course teaches experienced Lisp programmers how to attach their own data onto existing AutoCAD® drawing objects, and how to interrogate this data later. This extended data does not show up in the drawing nor does it appear in the AutoCAD List command, but it is available to knowledgeable programmers. The type of data that can be attached includes plotting parameters, client and project information, vendor and inventory data for component parts, and so on. We will work through an example that parametrically creates a 2D drawing detail of a coil spring and then attaches its specifications to it. If we want to edit the spring later, we can read its specs back from the attached data.
