I just downloaded and installed Unreal Datasmith plugin in for 4.24. into Revit 2020.2. With a model of 3 walls and a floor, I am getting the below error on export. What am I doing wrong?
Object reference not set to an instance of an object.
at Autodesk.Revit.DB.CustomExporter.Export(View view)
at DatasmithRevitExporter.DatasmithRevitCommand.Execute(ExternalCommandData in_commandData, String& out_commandMessage, ElementSet out_elements)
Can you wetranfer me the revit model? We are going to look at the crash here. Please send it to pierrefelix.breton@epicgames.com with your name and description.
I noticed is something related to the phases, infact exporting models without them is currently working…
I’m trying with a model with 90 phases (for 4d implementation) and it’s having that problem mentioned before…
Sent model to Epic Staff and they are looking at it. My model was very small with only 3 walls and floor added to the arch template. I used a larger model of an interior and it worked fine. Revit Interior was set to Complete with no overrides.
Hi Pierre,
it did not solve my issue, however I’m sending you the model via Wetransfer, please have a look to it, it continues to generate this error, also turning off all overrides.
Thanks
If this could help : I have the same problem and I cannot export from revit to datasmith with the same export error message.
The weird thing is that I can export an older file without problem (and only one…) but every other file has the same bug. I tried filters, removing phases, materials… and that doesn’t help. I even tried to create a new file (revit 2020.2) from scratch with an official autodesk template and … same error.
The file that works on export was created with revit 2020 (not 2020.2), so I tried to convert that file to a template for a new project with revit 2020.2 and got the same export error as the other files.
I tried to revert to revit 2020 without the 2020.2 patch, but every time I uninstall it, it installs the new one (2020.2) …
Perhaps the 2020.2 update may cause this problem ?
So far we have identified the issues on our side (the exporter plugin seems to trip over some entity types and fails). Ping me privately at pierrefelix.breton@epicgames.com if you have cases where our revit exporter crashes as reported in this forum we will see how we can help out.
Can you export Revit 2020.2 using the Datasmith exporter and 4.23? I am concerned because i have two projects that are now in Revit 2020 and I am not encouraged by the things I am seeing using 4.24 with them. I’ll give it a go in 4.24 but getting a bit nervous.
