For developers seeking a more intuitive API, significantly simplifies AutoCAD plugin code. This library works with AutoCAD 2015 and later and is available via NuGet:

Without strict management, a shared block network can quickly degenerate into a chaotic mess of duplicate files and broken paths.

Inserting a Block Reference

When inserting the BlockReference , you must parse the definition for attributes and generate matching references:
