AutoCADCodePack is a powerful library that help you to develop AutoCAD plugins using the AutoCAD .NET API. It re-encapsulates the over-designed and old-fashioned classes and methods into easy-to-use static modules and functions. It also brings modern C# syntax like functional programming to AutoCAD development. With all the features it provides, you can save over half the lines of your code.

 

We temporarily offer sources and binaries for AutoCAD R18 (2010, 2011, 2012) and .NET 3.5. You can target R17 or R19 with the source files and build yourself, but there should be some problems out of API difference. We will officially publish ports for R19 soon.

 

The library consists of the following modules:
