Frequently asked questions

No. HeyGemaâ„¢ doesn't model jewelry. You design in your CAD tool of choice, then use HeyGemaâ„¢ to turn that design into a photorealistic render for clients.
A screenshot or photo of your design from any CAD program, or a 3D file (.3dm, .obj or .glb). With a 3D file you can pick preset angles, orbit freely or use views saved in the file.
