I'm playing around with coordinates in autodesk forge and by some chance i noticed that some of the element(door in my case) doesn't have an fragment id. I've tried to use selection and fittoview to try and display which is the problematic element and to my surprise the element doesnt even exist in the viewer (I still managed to use getProperties to show all the properties though). Is this because of some bug occurred during the conversion from revit to forge or is it because of an error in my programming?
It seems to be expected that small objects get lost in Revit export processes, cf.:
How large is your missing door? How large is the model?
