I'm working with a couple of very large surfaces. They're being stored in external files. Over 1 GB each. This and other factors leads to the drawing being thrashed on a regular basis. After one fatal error I reopened the drawing and it gave an error message that it couldn't find one of the external .mms surface files. The instructions were that if I could find the file, close the drawing, restore the file and reopen the drawing.
I found a backup of the file in the temp folder and copied it to the drawing folder and renamed it to the original name. Now when I open the drawing the surface isn't listed.
Is there any way to restore that surface from the .mms file?

No. I ended up recreating the Surface. It only happen that once as far as I can remember.

Do you have any clue on what to do here?
@alansanudo, Unfortunately no. This happened 6 years ago and I haven't been working with Surfaces that big since then.

I'll provide my 2 cents... Reduce the cloud dataset, while we can capture data at the centimeter level does this mean we actually need all of it? I've been in the land survey/development scope for 30 years. And I see great things with the tech that is happening right now, the only problem is that the dataset is not something that is workable, I could go do a topo on a 25' grid (done that on airport runways, fun stuff right), and provide more efficient data than a drone. Added ten computers and additional time, same thing! I'm wondering where the effectiveness is (Knees on concrete is a killer). What purpose does all this data serve, if you really don't need but 10% of it to get the job done... Honestly, I'm with Tech completely, I just don't see the significates of it in the long run having done both design (storm/drainage) and surveying. Q=CIA and I'm not going to the moon (or Mars) on Jeff or Elon's ship, I'm grounded in simple principles. ADD the complexity of data, and now I've got to remove 90% so that the engineer has a workable file with 10%.

Something I'm dealing with at the moment. There's a question if we should use older 2 meter Lidar or wait for new 0.7 meter. I remember the tightest grid I ever shot with an instrument was 20 feet. The only makes sense to wait is because it will be used to model the whole County including building and a consultant is doing the processing.
