Grey Raster Images

Hello - I attached a bunch of raster images to my microstation file. I was able to crop and scale them as I like, all looked good.

Today I opened my file to find that a third of them are now just grey boxes. When I look on our network drive the photo is still there. When I try to attached it again I see the photo preview, but end up attached a grey box. What gives?

I am using MicroStation V8i on a windows 10 PC.

Thanks, Amelia

  • If you used the instructions from the EnvisonCAD website you will need to realize the raster cache files will have to be recreated each time you open a DGN file with raster images attached. If you set Workspace > Preference > Raster Manager > Memory > Raster Loadmode to Standard for a reason like raster images to display faster then setting Cache Manager to delete on Exit then your raster images will be slow displaying. For example a JPEG that takes 7 minutes to display will always take 7 minutes to display every time you open the DGN file. If you allow it to create the .ctiff (raster cache) file and not delete it then the next time the DGN file is opened it will take ~7 seconds. The raster cache sometimes may cause a problem and it a good idea to delete them when you have a problem.
