Remembers the last edited value of each design. 11. ASME Flanges 12. BIS Beams 13. Unit Conversion 14. Fluid and Solid density table, 15. Tank Volume Calculation Learn from : https://blog.truegeometry.com/tutorials/appIntroductionf3U.html 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.
