The Clipboard Manager plugin can be used with AutoCAD® to manage multiple clipboard entries, storing and renaming them for later use. It's great for moving different sets of content between various open drawings or for creating repeated copies of geometry without using blocks.
This plugin was first published as an ADN Plugin of the Month. The plugin has been provided with the complete source code needed to build the application, with the intention of encouraging users of Autodesk software to use programming to tailor the products they use to their specific business needs.
More information regarding this plugin can also be found on Kean Walmsley's blog about AutoCAD programming, Through the Interface.
