I am new to Dynamo and haven’t been able to find a solution to what I’m trying to do. I have some mechanical equipment that needs to have a tag in Revit that shows the bottom elevation of the equipment. I would like Dynamo to find the bottom elevation of all mechanical equipment with a specific name and report it to a Shared Parameter so I can use it in a tag. I’ve tried several approaches without any success. I believe my latest path is one that I should follow. I am able to get a list of all the equipment I need to extract info from but I can’t seem to go further than that. I believe I need to break down each units surface and select it in Dynamo and get the bottom elevation from that. Here is what I have so far. Any suggestions?
Note that I am trying to explode the geometry but getting errors, I’m sure it’s simple but don’t have the experience to figure it out. Thanks.
