I have added a new freeware on my website.
It is a free plug-in created in VB.NET 2005. Use ADTListDefinition to import, create and export ListDefinitions quick and easy.
You need ADT (Autodesk Architectural Desktop) or ABS (Autodesk Building Systems) to be able to use this program. In the Style Manager>Multi-Purpose Objects there are List Definitions (introduced in the 2007 versions) that can be useful for many purposes. But you have to add them one by one. Imagine if you have an existing list of many items in Excel or some other format and you have to add them manually. Another thing is that even though the list in the Style Manager shows up sorted the list is sorted in the order the items where added when the list is used in a Manual Property Definition, Space name or Zone name. So if you want the items in alphabetic order and add one that is not supposed to end up last you have to add all again. This is one reason when this tool comes handy.
Tip. ListDefinition is the command to start the Style Manager with only the List Definitions.
