Transfer holes in concrete elements from one model to another?

I have been away from Dynamo and Revit for 18 months and now i’m back! :slight_smile:

I need to automatic transfer holes in concrete elements from one model saved as a Revit file to another model saved as an IFC file.

I thought of opening both models in Revit and use Dynamo to transfer the holes. If I remember correctly it were not possible to open two models in dynamo at once. Has it changed? (Could not find the option) if so, how do I import two models? If it is not possible, does anyone have a suggestion how this could be done?

…and where can I get an update on the most awesome new dynamo features from the past 18 months? :slight_smile:
