I recently opened a file with AC16 that was created in AC15, and found that the mesh was not visible in 3D. It is however, selectable in 3D. I thought that it might be a resource issue because the file is very large, ( 208 MB ) so I copied just the mesh to a new file, but got the same result.
Another file created in AC15 seems to work fine, though it's much smaller. ( 58 MB )
Any help would be appreciated.
