Public Revit 2011 SDK Posting

The Revit 2011 SDK is now available on the public Revit Developer Center site.

Here are some of the last-minute changes documented between the beta version and this one:

Two existing properties have been re-implemented to better complement the changes in the transaction framework:


The FamilyHostingBehavior enumeration represents the type of host a family expects. The value for a particular family can be obtained from the family’s built-in parameter FAMILY_HOSTING_BEHAVIOR.

FamilyInstance.Host property improved

The FamilyInstance.Host property will now return the host element of faced-hosted family instances. Previously it returned null.
