To use the AutoCAD^® .NET API effectively you should be familiar with the AutoCAD entities, objects, and features related to the tasks you want to automate. The greater your knowledge of an object's graphical and nongraphical properties, the easier it is for you to manipulate them through the AutoCAD .NET API. For information specific to the members (methods, functions or properties) of an object in the AutoCAD .NET API, see the AutoCAD .NET Reference Guide.
