Hi @MelleH …does it work if you uncheck “default value” in your document input in the ifc export node…

Ps …and .remember close the background open document

Thanks for your reply.

I’ve tried the default input but is doesn’t help…

Maybe @Alban_de_Chasteigner can help you, i assume the “Export IFC in Document” node is from the Genius Loci package.

5

do you have the ifc exporter installed ?

6

I just installed the addin and tested it but still didn’t work…

Hi,

There are been somes changes in the Rhythm package lately. The Export IFC in Document node expects a Revit.DB.Document and not a Dynamo Revit.Application.Document.
Use the new Rhythm Documents.DynamoDocumentToDbDocument node to perform the required “conversion”.

Thanks a lot!
This made it work!

Now that this is workin I tried it for multiple models at once.
I feed the node 3 models with the 3 views and the 3 names.
It creates 3 IFC models so that works. But the problem is that all 3 models are the same first model.

You need to set the longest lacing on the Export IFC node with several documents.

Thanks!

Sorry for all the questions but I broke apart your node to customize some of the export the settings.
All of that works great but how do i turn on longest lacing of someting simular for a Python node?

We would have to see how you have edited the Python to help with editing the code.

That said it’s likely easiest for you to generate a new custom node which would allow you to utilize lacing and list levels as you would any other Dynamo node, rather than fighting the loops on the edited code.

Thanks!
I fixed it by creating a Custom Node!

Hi! can you share your DYN file? it will be very helpful thank you

Hey,

I have since moved away from using dynamo and started coding everything in python using PyRevit. I can send the file tomorrow. I am not sure if it will still work tho

Hey,

Here is the dynamo script.
I have not used it in some time.
Ive given some small instructions in the script of things to edit to make it work for you.
This specific script exports a predefined 3D view of the current open model.
There is some frozen code that can be used to export another file i think.
Make sure to edit the File path in the custom node to your Propertyset.txt

Thank you very much, unfortunately I can’t use pyrevit.
SentinelOne sees it as a virus and I can’t whitelist it (I have a company computer) so I fell back on dynamo
