[QUOTE="Sarah Downs, post: 295255, member: 20317"] Hello Wannabe! The way I went about it: 1. Download Meshmixer. It's free, and relatively easy to use. 2. Find your case, right click and advanced -> explore order. Inside the CAD folder you'll find the teeth you designed in DCM format. Open all of those and they'll pop up in the 3Shape model viewer window. Don't close the window; keep it up with the teeth still in it. You might also want to copy these files somewhere easy to find, too, like a folder on your desktop. 3. Next, go into your Scans folder. Whichever arch is your working arch (upper and/or lower) you'll find a couple of different versions. One should be the unaltered scan, which is the incorrect position. The other will be the scan that's had the vertical altered. Open them both and check them against the position of the teeth you still have open in your 3Shape viewer. One should line up correctly. Copy the one that lines up to your easy-access desktop folder. 4. This next step kinda depends on how you originally set up your order. If you designed individual teeth, this will take longer than if you made a bridge. It's specifically for issues like this that I always set diagnostics up as bridges if I can. You'll want to make a dummy file with a single unit in 3Shape with as many different scans selected as possible in the work order (working arch, antagonist, preprep and double prep). Name it something temporary, save it, right click it and hit "import scans," then go through your easy to find folder of scans you copied and import them, teeth, working arch and all. Position doesn't matter; 3Shape remembers the XYZ coordinates regardless of which scan you're importing. You're doing this to convert the files from DCM to STL. You might need to reset the case or make more than one to convert all of them if you have a bunch of individual teeth, but after you've imported the scans, right click the case again, go to advanced -> export scan. Save the files somewhere easy to find again and MAKE SURE you save them as STLs in the dropdown menu at the bottom. 5. Open Meshmixer. Take the teeth scans and working arch scan you converted into STLs and drag them and drop them into the Meshmixer window. Hit ctrl+A to select everything. On the left there will be an option to "combine." Boom. Solid model with the teeth. Just go up to menu again and export as STL. From here you have a file you should be able to set up in 3Shape model builder normally. This is a pretty involved process, but it's the one that always works reliably for me.
