Support Revit Elements

[teocomi]

We could easily support Revit elements in streams that go Dynamo to Dynamo. It would mean creating new ObjectModels although they're wouldn't be supported by SpeckleCore. To do so we'd need to:

• [ ] Create a SpeckleDynamoRevitConverter project (or extend SpeckleDynamoConverter)
• [ ] Define the new object models (eg, grid, level, family instance...)
• [ ] Move serialization/deserialization logic to the Functions project since Revit transactions cannot be directly started directly from the NodeModel nodes (unless I'm wrong @mjkkirschner)

Hi @teocomi - why do you believe you cannot start transactions from nodeModel derived nodes? You might be able to do this with some data bridge callbacks inside the AST. I could be missing something though :) - Can't say I have done this anywhere that I can recall.
