AutoCAD Architecture Classification Definitions cannot be exported or imported. With the help of ClassificationDefinitionTools this is possible. Some classification structures can be very large and complicated and this tool can help to avoid the need to type everything manually.
In the Style Manager>Multi-Purpose Objects there are Classification Definitions 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.
Tip. ClassificationDefinition is the command to start the Style Manager with only the Classification Definitions.
To install and run ClassificationDefinitionTools do like this:
Download the plug-in.
Extract to a folder somewhere locally on your PC.
Load ClassificationDefinitionTools.dll using the NetLoad command within the application.
Use the either of two commandsClassificationDefinitionImportorClassificationDefinitionExport. (Tip. Type Clas and use tab several times)
