It looks like the interproximals were not scanned. Nothing wrong with the .OFF files BTW , same idea as an STL, different encoding.Hi
Is there any special way to deal with .off files ? It's always like this, once I click on the the margin detection button some scan data are lost
So, if your friend scans the case, all he needs to do is to send you the upper and lower scans saved in occluded relation to each-other. Tell him to scan the die separately, or he could scan a solid model if the margin is clearly visible and he can capture the interproximals without any holes.
He would have something like this, upper and lower occluded:

Turn visibility off for everything, but one arch... the lower in this pic. Right click and save scene:

Pick either scene, resulting in a bigger file or STL, OFF or OBJ. The OBJ is the same idea, but it has texture info as well in case you have a color scan:

From this point you could import the scene file and continue on your system, from where your friend did save it. Or switch visibility to the other arch and repeat the process.
Click default coordinate system when it asks for:

At this point you have two files of whichever type was chosen, saved in relation to each other. When you import, there's no need to align them.

My example showed an IO scan, for a model with a removable die the process is the same

Hope this helps
