If you have the new ModelAN3D Pro version, you can share your entire 3d scene with your friends. Access to the menu options, and select Share Project. You can send your scene using Gmail: select contacts and send. This mail have attached one file *.oea with all your scene.
Users that have installed ModelAN3D >1.7 version can open this file and view the scene. Sometimes is necessary re-start the Gmail process to recognize the *.oea extension (if you have installed ModelAN3D >1.7 recently). Otherwise you can save this file into sd card and open directly.
