Export formats for Geometry: OBJ,PLY,STL,DAE, GLB & GLTF

The app provides a gateway to generate true geometry from engineering to free form shapes, on your mobile and computer. The geometry created can be used to print 3D models via 3D Printers. The geometry created can be imported to any 3D software application, including Microsoft's "3D Viewer".

One time purchase gives access to unlimited design generation and sharing. However this subjected to computing cost.
