Cones Calculator – Flat Pattern Layouts for All Conical Shapes The Cones Calculator App is a powerful tool for engineers, fabricators, and workshop professionals to calculate flat pattern layouts for all types of cones and conical shapes. Whether you are working on pressure vessels, heat exchangers, storage tanks, or piping systems, this app simplifies the process and saves time while reducing fabrication errors. Key Features & Layout Types: Truncated Cone (Half Cone): Calculate layouts for full cones, half cones, or truncated cones. Enter small & large diameters and height to get development radius, angles, and cord lengths. Ideal for concentric conical hoppers. Multi-Level Truncated Cones: Divide large cones into multiple levels when sheet size is limited. Each level can be laid out individually, then joined via welding. Input large & small diameter, cone height, and number of levels. Eccentric Cones: Calculate layouts for eccentric cones using the 24-part method, with top and bottom markings for accurate fabrication. Multi-Level Eccentric Cones: For large eccentric cones, divide them into multiple levels and generate precise layouts for each part. Input large & small diameter, height, and number of levels. Tori Cones (Knuckle Cones): Generate layouts for tori cones with knuckle at the large end or knuckle at both ends. Input large & small diameters, knuckle radius, and straight face for flat pattern development. Why Use Cones Calculator: Recommended to use mean dimensions for ready-to-use fabrication layouts. Generates accurate development radius, angles, and cord lengths instantly. Ideal for daily fabrication tasks and complex conical shape layouts. Helps engineers, fitters, and contractors save time and avoid errors. Who Can Benefit: Perfect for: Fabrication Engineers & Fitters Production & Design Engineers Workshop Supervisors & Fabrication Contractors Piping Engineers & Process Equipment Manufacturers Pressure Vessel, Heat Exchanger, and Storage Tank Fabricators. Applications: Concentric Full Cone, Half Cone, and Truncated Cones Multi-Level Cones – for large-size cone fabrication Eccentric Cones – widely used in pressure vessels & hoppers Tori Cones – knuckle at large end or both ends Daily Fabrication & Layout – saves time, reduces mistakes. With Cones Calculator, layout complex conical shapes quickly, accurately, and efficiently, directly from your device. Whether you’re in the workshop, office, or on-site, this app provides ready-to-use fabrication layouts for all your engineering needs.

Verdict

The call

The clearest difference is price: Sheet Metal Calculator at Free against Cones Calculator's $2.99. Sheet Metal Calculator also leads on rating (1.4 vs 1.0) and update cadence (every 4 months vs every 73 months). Cones Calculator's advantage is in-app purchases (none vs 3). On ads, monetization model and device support there is nothing between them.
