The ADN plugin of the month for December is the Layer Reporter for AutoCAD 2007 (and later) that was written by Terry Dotson, from DotSoft, and edited by Kean Walmsley for publishing on his blog: Through the Interface.
The plugin generates a report of the layers used within an AutoCAD drawing. The report formatting can be customized and the customized settings are applied when the tool is used on other drawings. The resulting report can be printed or saved to a web page (HTML or MHT) or plain old text file.
Sweetening the pot to help others to develop their own plugins is alive in the lab.
