Hello @Cadguru42,
This sounds like an issue related to Element Binding. There were similar discussions about this topic. You can find a detailed explanation here.
Ok, but what if you don’t want element bindings? There are two methods to fix this which use. I recommend doing a save as in both cases, and checking the before and after carefully when done.
- Open a new Revit file, then open the .dyn in Dynamo, disconnect all nodes which ‘start’ the graph (basically disable anything in the ‘gather’ stage of your workflow), and run the graph. Quickly confirm that the many errors have produced a null result on EVERY node which interacts with Revit. Normally, this would be bad, but in this case… save the graph, reconnect the selection nodes, and save the graph again. The bindings should have been removed. Alternatively you can replace the nodes which create Revit content with new versions - copy/paste is your friend. This can be difficult as you may not know every node in your first pass. Both of these methods are more ‘user friendly’ to perform, as they keep you in the Dynamo user interface.
- Open the graph in a text editor, find the “Bindings” section, and remove all the content in the brackets. Be sure to catch it all and not mess with anything else - you may corrupt your .dyn otherwise. This is nice as it can be automated (with Dynamo even), and as such can be performed quickly on many files at once.
Let me know if this does not solve your problem.
