BlackBox Right Click Rename
Right Click Rename for AutoCAD® allows a user to select a single Entity, and contextually rename its Entity-specific properties, as supported by the RENAME, or -RENAME Commands, from the context (right click) menu.
So there's no more need to use the RENAME dialog, and hunt down multiple item(s), etc... Simply select the desired Entity (i.e., a Block, Dimension, Polyline, Table, etc.), and Right Click Rename that Entity's Block Name, Layer, Dimension Style, or Table Style, etc. The Entity's existing property name is supplied for you at the command line, so you need only type the new property name. Lemon squeezy.
Please note that default items such as "0" (zero), and "Defpoints" layers, "ByLayer" Material, etc. cannot be renamed.
This plug-in is only accessible from the context (right click) menu, when a single entity is selected, and supports AutoCAD-based products 2010-2014. This plug-in is automagically loaded for you in 2012 and newer versions which support Autoloader. To load this plug-in for 2010-2011 versions, simply NETLOAD the appropriate assembly located within the ./Contents/Support/ folder.
