Sir, I have the same problem in plumbing models. In my model of the Revit plumbing specialty I have these elements but when I export it to speckle web certain elements do not appear and in the report of the speckle plugin show a error signal.
Hi Joffrey, how are you?
I have the same issue as you, some elements (most of them) are not showing on the Speckle web viewer.
I thinks its because of the revit version and revit connector.
I tried uploading the same model with revit connector but in REVIT 2024 version instead of 2021, and it works just fine.
I know that sometimes you cant just upgrade the revit version of a model because of the client requirements.
I hope that the problem gets solved, as i use revit 2021 too.
Sadly, @Joff_20; @NicolasRivero is very much correct. Revit 2021 API has a bit of a bad reputation for not supporting certain features. I don’t expect any updates from Autodesk with 2021 out of support. Therefore, we’re out of luck with how to help better. Other than, say, we have increased support for MEP elements by a considerable margin, which we’ve been able to do this year where possible - but in versions later than 2021.
