With version 10, the application allows you to quickly visualize relational values related to pipes and elbows (Carbon Steel / Stainless Steel) according to ISO / ASME standards, making it a practical tool for industrial piping. An ultra-fast and intuitive way to retrieve: Diameter → Angle → Radius → Extrados → Intrados, regardless of the angle or diameter, in a single step. This provides up to 810 possible entries with one click. With this version, you can choose how to control diameter selection: via a slider, or via pre-filled input fields. ElbowData is free forever. Features Elbow formats: 2D / 3D / 5D Segmented elbows (lobster back): 8 generators / 12 generators / 16 generators PDF abacuses and isometric sheets including: bill of materials based on the selected language, technical memo, generator templates Inch / millimeter conversion Scientific calculator optimized for industrial piping Saved language selection This version benefits from UI, design, and ergonomic optimizations. Advertisements are now non-intrusive, ensuring a smooth and free user experience, with rewarded ads and technical articles related to industrial piping. You can support the developer with your suggestions and/or access the premium version. Thank you! If you have any feedback about the application, feel free to contact me by email.
