A UI Toolkit is essentially a tool used by developers to create the user interface for a program.

I previously posted about the apparent limitations of the current Revit UI Toolkit.

In David Conant’s post on Inside the Factory, we get a similar insight into this fundamental yet apparently weak element of Revit development.

Some are the result of constraints imposed by current interface tools, others reflect deeper issues in the Revit data structure and regeneration engines.
