Element Data Extension Coder of Revit Addin Wizard for Revit .NET API

In this article, let us look at a new code that Revit Addin Wizard (RevitAddinWizard) provides, Element Data Extension. It is to create the super easy and cool Element Data Operator and/or Element Data Extension.

It can be found from both the Revit Addin Coder menu group under Tools and the toolbar with the same name from right click context menu. After the menu item or tool icon is clicked, the Element Data Extension coder window will show up:

 
If both the Element Data Operator class and the Element Data Extension class options are checked off as above, both help classes will be created. Here they are.

In terms of how to use the super easy and cool Element Data Operator and Element Data Extension coders, please refer to earlier posts for detailed instructions and code examples.

RevitAddinWizard will provide more cool coders and widgets in the future. Please stay tuned.
