Hi all,
I had a meeting today with someone from Progress Group about the PXML export from Revit. It appears that the POS (position number) is missing in the PXML export from Revit.
We export reinforcement cages for beams in PXML format. Does anyone know if this POS value can be configured/added somewhere?
At the moment, all bars and stirrups are exported as individual, ungrouped elements, which results in a very long bending schedule in BFW.
Seems like an export from Tekla to pxml is working fine. Looks like only Revit has this problem.
If pxml is just a variant on an xml file or is natively read/writeable and there something you can check in an entry in revit such as elementid/mark then you should be able to programatically edit the file using dynamo and python.
Have a stab at it and advise where you hit issues. If the first issue is not knowing dynamo then throw the problem at AI I’d say. Its very specific and likely needs some effort put in to get it moving.
Hi Gavin,
Thanks for your reply.
Dynamo and python are no problem for me. But I was hoping to get it fixed by Autodesk.
Attached is an example of a PXML export containing three brackets. As you can see, no element ID or mark is exported by Revit. Therefore, searching for these attributes is pointless.

IF there is a specific issue in revit, then you are best to speak to Autodesks main support.
Also there is the revit forum too, though have a look at the below as it talks about configurations as long as you have the specific addon/tool installed?

I think there is an issue in Revit.
Please see the fragment below from a Tekla export to PXML. It concerns the <Pos> field.
This field is missing in the export generated by Revit.
I have also included a fragment from the Progress Group documentation, which specifies how a PXML file should be structured.
I will also post my question on the Autodesk forum. In any case, thank you.
You might be better off handling this over on the Revit forums, these generally deal with Dynamo if you’re not hoping for a workaround facilitated by Dynamo itself. The Revit devs don’t see things here, just the Dynamo ones.

As @GavinNicholls mentioned if you feel there is an issue the official forums are the right method to surface the issue.

The feature itself doesn’t seem accessible via the API and therefore Dynamo cannot help without someone building a custom exporter from scratch.

I agree it’s probably best addressed with the developers of the structural precast extension i.e ADSK
However- this might take some time.
You could possibly achieve a similar thing with Dynamo- although I’m no expert in how these precast elements are structured (in a data sense)
I’ve done quite complex XML exports using Dynamo (for other purposes). Sometimes other tools are necessary if Dynamo can’t get it 100% there.
