I am opening different saved versions of a DWG in Navisworks and comparing their contents. When I originally opened them a few hours ago, some newer files had a property tab titled "dimensions" while the older files did not. However, when I tried to open the same DWG files in navisworks again, none of the versions had a "Dimensions" tab. I need the dimensions property as I am uploading to Assemble and need the elements lengths.
I have tried re-downloading the files, changing my selection resolution, opening versus appending, clearing my navisworks cache, but no combination of these strategies is bringing back the Dimensions properties.
What is going on? Is this a bug or did I corrupt my files somehow?
