We have a Doc next door that wants me to import the Itero scan into 3shape, design off that only, not to scan in the itero model. I get better occusal on the opposing model and even the prep model. We are not level 2 or 3 of itero so We have to wait until itero creates the model then I can export the scan stl files from his aligntech account then import on my end. We still verify the fit on the itero model, but so far so good we almost have our setting dialed in to the point where we might jump up to level 2 or 3 itero and receive scans straight from the docs and go model less, but We have a 3d printer in mind just to create a very small solid just for contact verification. Model less is only going to be for single unit(s) cases, no bridges.
