Convert 3dm to obj

Christopher2 · April 12, 2017, 5:10pm

Hello,

I received a 3dm file from my orthodontist. It is a 3D scan of my teeth and gums. I cannot get it to open with Rhino. Is there anyone who would be willing to try and convert this file for me? I would like to get an OBJ. Please email me if you can help.

generally for everybody to see and know, there is a dental 3d scanner which produces the same file extension as rhino just be aware that this can not be opened by rhino.

Bummer. Is that just a file header thing? Can this be hacked somehow? Where would you look next to try to convert this file?

Thanks again.

hi i actually had written you a pm but i post this here again maybe its also interesting for whoever encounters this.

On another topic

hi Christopher,

it took me about 2 hours to find out what that thing is, first of all its not a rhino file it is from cadent, it coincidentally has the same file extension. they only way this can be opened is with Orthodent. you can download it for free and install it. i extra went to my window partition to try that and that works. but you seem to be stuck there not able to export you can view your teeth though. there seems to be an option to export to stl files which is a stereo lithographic file for 3d printing this you could open in any 3d application, but that only works when you log in and this does not seem possible… maybe you have to be a dentist to do so. i dont know what you need that for but either you ask where ever you got that file from to export it to stl for you, or you have to rebuild it with jpgs which you can export at least yourself.

sorry cant help you more there.

Thank you so much for doing all the leg work there. I was a bit lost. I appreciate all your time and effort. I will contact my orthodontist and see if they would be willing to provide the stl format.
