Batch process on Multiple drawings

[mzjensen]

You would plug the ExternalDocument.LoadFromFile node into ExternalDocument.Save, but make sure you add a gate before that to ensure that the previous operation (freezing) completes before the drawing is saved. More info here:

Passthrough, how can i understand that?

It is simply just creating a list and then getting the first item in the list. So it could be rewritten as: List.FirstItem(passthrough,waitfor); Or you could even simplify it further and just do a code block with: [a,b][0]; It acts as a gate because Dynamo has to “collect” all of the items in the list before passing the contents on to the next node.
