Pushing back and forth metadata between copy monitored model elements.

[Anonymous]

Hi Forum members, long time lurker here, whose butt has been saved many times by the insightful folk herein, so, thank you!

I have a question that I'm hoping someone here can rain light on..  Like many of you, we receive Revit models from our Architects, we more often than not will copy monitor grids, levels, walls that will be loadbearing/shear walls etc into our structural model and we start our work from there.

I'm working on 2 planes here, one, where we need to submit drawings for permitting to the local authority and the model is taken up to LOD 3-400 from concept through to construction documents.. Nothing unusual there I think.  But then we also want to populate our (copy monitored) walls with metadata (just text fields) that will essentially drive a 3rd party application (HSBCAD) to create shop drawings and then machine code that will run CNC lumber and framing machines for building out of wall panels. 

We are trying to figure out the best approach, and we believe due to the fact that we don't have non-loadbearing walls in our structural model, yet they'll need to be framed,  we should "push" back the metadata from our structural loadbearing walls in the structural model, to the Architectural model.  Then using a simple select all instances technique apply the metadata required for the non-loadbeaing walls, which should more or less always be the same.  This would also need to be done for window/door openings, too. But I think if we can suss out one aspect of this riddle, the other should fall into place. 

Does anyone have any idea about how we may possibly go about this, even if it's at all possible, or do you have another idea about a better way we should go about addressing this workflow? 

As a pre-requisite, both models share the same shared parameters and we're in Revit 2017.2. A simple copy and paste from one model to another brings in the populated metadata, so I do think it is possible!  

Many Thanks all for looking, and happy Revitting!

You can copy monitor both load bearing and non-load bearing walls to enter the metadata, but keep them in different worksets.

Hi ToanDN,

Thank you for your response. The process of copy monitoring the walls I'm all set on I think. It's more the developing the metadata information in the structural model over time, then pushing back this metadata to drive the manufacturing process that I'm stuck on. I honestly thought I had a breakthrough today via Ideate BIMlink. Creating a wall schedule from both models and matching the walls ID's and then copying the metadata from the Structural wall schedule to the Arch wall schedule and then back into the Arch model once we're ready. But a copy monitored wall has a completely different ID, GUID and Unique ID (I kinda knew that one would be different!)..

Still scratching my noggin over this one! The saga continues...

That is exactly why I wrote what I wrote. You keep the metadate in one file only so that you have a complete control over it. Don't push the date back to the arch file.

Thanks again for your advice on this one, ToanDN.

I spent last week exploring some more channels, as whilst what you stated was correct, we will need this for many other elements eventually, certainly doors and windows now, and eventually any opening that will need to be machine cut, so just about everywhere a service penetration is made. I think you'd agree these are not things we'd ever want in our structural model, on a hidden workset even. 

Thinking of the bigger picture here, we've began exploring a recently Autodesk acquired software developers product; Assemble. Which pertains to have within it this very functionality. 

I'm yet to get my hands on it for a real test, but I'll update here as to my findings. 

Again, thank you for taking the time to respond, and apologies in me delaying getting back to you.

Cheers!
