Hello dear Specklers,
this is a complicated case about Updating a Revit Model … and I don’t want to bother you with unnecessary details because this is a user issue on our end.
The rough situation in case you want to really read it
- initial Revit Model in concrete was modelled manually in Revit
- We scripted a steel bridge for the concrete buildings in Grasshopper and send it to Revit
- After a while the architect wanted to change its design
- After modifying the design and receiving the new geometry in Revit. The beams are now send on the wrong height whatever we are doing … in Rhino and in the Grasshopper definition they were right
- Hint: Colleagues deleted the initial received beams
- The strange thing … receiving the geometry in a new file and it is completely correct … receiving it in the inital Revit file … wrong height
- The coordinate system is fine too.
We solved it for now by receiving the geometry again into a clean slate file and then linking it into the original Revit Model … binding it afterwards.
Now to my question:
I have the feeling that there is something messed up in the initial Revit project file. Where is Speckle storing the information of the history? …We want to create a clean slate inside of the original Revit file and try again
I want to spare you with more details and from investing time for the deconstruction of this issue, therefore I did not attach any files to this post. I’m happy with a simple answer … in case there is one 
Thanks and all the best,
Alex
