NewFamilyInstance Workaround

[grahamcook]

I thought i would share what appears to be a workaround when placing new instances of families using the NewFamilyInstance method (2014).  I was using the following overload to place an electrical socket in a wall:

Document.Create.NewFamilyInstance(XYZ location, FamilySymbol symbol, Element host, Level level, StructuralType structuralType)

This was successfully placing the family instance, problem is i then wanted to flip the face using the familyInstance.flipFacing() method which always returned false even though i could flip the instance through the user interface.  But i found if i place the instance, commit the current transaction, then attempt to flip the instance in a new trasnsaction then it worked.

Hope this helps someone else who may be fighting similar issues with the NewFamilyInstance method.

Actually, doing a Doc.Regenerate() between placing the instance and flipFacing has the same effect and is obviously more straight forward.

Dear Graham,

Thank you very much for this important hint.

Actually, the topic 'Need to Regenerate' is a big and important one.

Omitting a required regeneration can cause a lot of head scratching, not to mention headache:
