Several people have recently asked how to get started with Forge Design Automation for Revit or DA4R. I will not get into any nitty-gritty details, since they are well covered by the Forge Design Automation API documentation, which includes DA4R tutorials and samples. Here are examples of two conversations on planning first steps for DA4R solutions – Structural analysis with DA4R – Implementing a DA4R RVT round trip...
Today I discuss the next step in my IfcSpaceZoneBoundaries project, how to prepare a Revit add-in for use in the DA4R or Design Automation for Revit environment and figuring out how to best handle it in the VS solution – Context, add-in functionality and history – Preparing the add-in for DA4R – Local testing versus live deployment – User defined input arguments for DA4R – Logging of results...

An interesting question was raised on renaming a family after it has been loaded into a project, which throws some light on the underlying relationship between the family name and the
Before that, we revisit the eternal topic of getting started with the Revit API, and what to do to prepare for it before actually touching Revit at all.
Afterwards, and similarly, we pick up a good suggestion or two on planning and preparing your extensible storage schema for future version handling
