Anyone know how to make this work? Right now the definition will export all images, but fail to change the parameters first. It’s all null’s.
It’s built on Michael Kirschner’s work on Changing a Family Instance and Saving an Image, and I use latest daily (DynamoInstall0.7.5.20141121T0127) on Revit 2015 UR4.
I’m guessing there’s something wrong with my use of Transactions and Compose Function nodes, but fail to see what. Dyf, dyn & rvt zipped and included below.
