I have installed the service pack 2.1 and am still getting the message
"external surface not found" find the .mms file. I think this is only
happening to surfaces created with the service pack 2.0 installed. I have
turned off my autosave and rebuilt all the surfaces in a drawing. Do I need
to recreated the surfaces for these projects? Is there a best way to fix
this?
Yes, I think you have the unlucky job of recreating that surface. SP2 would create a MMS file in certain issues - and some would loose the MMS file and the surface.
Unless your surface is 2 million points or more, a MMS file should not be created...

I have a DEM surface created from just over 1 million points that loads and works and saves just fine without creating an .mms file. But I wanted to create a copy of that surface and paste in another small surface made up of a couple hundred points. So I create a new surface and paste in the original DEM surface (with a million points) and even before I paste in the other surface that I want to add to the copy of the DEM surface I cannot save it without it giving me the message that an .mms file has been created. Why does the original surface not require an .mms file while a copy of the surface does?
One of our projects has the message about an .mms file not found. I have recreated the surface but the message still pops up. I have tried to save as another file and rename, but the message still pops up. Any suggestions?

I get the exact same thing, but in 2012. Any fix available today? I just "upgraded" to 2012 from 2010, but I never had this issue in 2010. I can see my surface just fine, I can do volume calcs with it just fine, I can edit and save it just fine.... But, when I go to plot, it's not found and not plotted! Drives me nuts.
