Cones Calculator Pro vs Sorphase

Cone Calculator is a professional engineering and fabrication tool for developing accurate flat pattern layouts for different types of cones and conical components. Designed for fabrication engineers, fitters, mechanical engineers, workshop professionals, and industrial manufacturers, the app simplifies complex cone development calculations and provides practical dimensions for plate marking, cutting, and fabrication. It is useful for pressure vessel fabrication, process equipment, piping, heat exchangers, storage tanks, ducting, and general sheet metal fabrication. Supported Cone Layouts • Full Cone Development • Half Cone Development • Truncated Cone Development • Multi-Level Truncated Cone • Eccentric Cone Development • Multi-Level Eccentric Cone • Tori Cone / Knuckle Cone • Tori Cone with Knuckle at Large End • Tori Cone with Knuckles at Both Ends Full, Half & Truncated Cone Generate flat pattern developments for concentric conical shapes. Calculate the required development dimensions, radius, angles, and cord lengths for plate layout and fabrication. Multi-Level Truncated Cone Develop large truncated cones in multiple sections when the complete cone cannot be manufactured from a single plate or when available sheet or plate size is limited. This provides practical development information for fabrication and assembly of large conical components. Eccentric Cone Generate flat pattern layouts for eccentric cone transitions using the supported development method. The calculator provides development information and marking dimensions for the top and bottom profiles, making it useful for offset and eccentric fabrication applications. Multi-Level Eccentric Cone Develop large eccentric cones in multiple sections for applications where a single-piece development is impractical because of component size, plate dimensions, or fabrication requirements. Tori / Knuckle Cone Calculate flat pattern development for conical components incorporating knuckle geometry. Supported configurations include: • Knuckle at Large End • Knuckle at Both Ends • Straight Face Dimensions Features • Accurate cone flat pattern development • Full cone layout • Half cone layout • Truncated cone development • Multi-level cone development • Eccentric cone development • Multi-level eccentric cone development • Tori / knuckle cone development • Development radius calculation • Development angles • Cord length calculations • Fabrication-ready marking dimensions • Metric and Imperial unit support • Automatic unit conversion • Simple and professional interface • Fast calculations • No internet connection required • No distracting advertisements Applications Cone Calculator is useful for: • Pressure Vessel Fabrication • Process Equipment Fabrication • Heat Exchanger Manufacturing • Storage Tank Fabrication • Piping Fabrication • Sheet Metal Fabrication • Ducting and Transition Fabrication • Industrial Equipment Manufacturing • General Fabrication • Workshop Layout and Marking Designed For • Fabrication Engineers • Mechanical Engineers • Design Engineers • Production Engineers • Fabrication Fitters • Workshop Supervisors • Fabrication Contractors • Piping Professionals • Process Equipment Manufacturers • Engineering Students Cone Calculator helps reduce manual geometry calculations, save fabrication time, minimize layout errors, and improve accuracy when transferring developed dimensions onto plate or sheet metal. Whether you are developing a simple full cone, truncated cone, eccentric cone, large multi-level cone, or knuckle cone, Cone Calculator provides a convenient engineering tool for practical fabrication and layout development. For fabrication-ready results, using appropriate mean dimensions during layout development is recommended where applicable.

Sorphase 3.0 turns your iPhone and iPad into a field-ready OTDR trace workbench. Open standard SR-4731 (.sor) files, keep them organized by cable, judge every event against published limits, average both directions and hand over a clean PDF report — offline, with no account and no subscription. NEW IN 3.0 - Trace library: import many SOR files at once, or share a .sor file from Files, Mail or AirDrop and choose Sorphase. Byte-for-byte copies are kept on your device and grouped into jobs by cable or project. - Pass/fail thresholds: presets use ANSI/TIA-568.3-D component limits (0.75 dB per mated connector pair, 0.3 dB per splice, cable attenuation and return loss). Add your own stricter project profile. - A–B cursors: tap to place cursors, zoom and nudge by one sample. Read distance, two-point loss, least-squares (LSA) attenuation in dB/km and a 4-point LSA event loss. - Fiber sections: every span between events gets its own least-squares attenuation, plus a length-weighted mean for the link. - Bidirectional averaging: pair A-to-B and B-to-A traces. Events are matched and averaged with (loss A-to-B + loss B-to-A) / 2, so gainers and exaggerated splice losses cancel out. - Macrobend check: overlay up to six traces. When 1310 and 1550 nm (or other wavelength pairs) are loaded, events whose loss rises by more than your threshold at the longer wavelength are flagged. - Cable summary: see pass/fail, length, loss, worst splice and worst reflectance for every fiber in a job. Export it as PDF or CSV. - PDF reports: trace plot, event table with results, fiber sections, link summary, identification and the method used. Share or save from the built-in preview. - Decoded file details: cable and fiber IDs, locations A and B, operator, fiber type, build condition, instrument and software from the file. Event codes are decoded too: reflective or not, found or added, end of fiber, loss technique. - Wider file support: SR-4731 revision 1 and revision 2 layouts. The CRC-16/XMODEM checksum variant written by some instruments is verified as well as the standard CRC-16/CCITT. - Units and corrections: kilometres, metres, feet or miles. Change the group index (IOR) to rescale every distance, and apply a helix factor to convert fiber length into cable length. - Loss budget calculator: length x attenuation + connectors + splices + other, with an optional power budget and margin. Fill it from a trace and compare it with the measured total loss. Also available as a Shortcuts and Siri action. - Sample job: five clearly labelled synthetic traces let you try every tool before you import your own files. STILL AT THE CORE - Stored samples plotted with min/max buckets, so narrow reflections stay visible. CSV export keeps every sample. - File integrity is checked. A file with an unrecognized checksum opens only after you confirm, and stays marked unverified in the app and in reports. - The import diagnostics list every block, the source SHA-256 and the reader notes. WHAT TO KNOW Sorphase reads binary SR-4731 files with one pulse width and one standard data group, up to 16 MB and one million samples. Multi-pulse files, vendor container formats and text exports are not supported. Event loss and reflectance are the instrument's stored values. Sorphase adds standards-based calculations (least-squares fits, bidirectional averages, loss budgets) and shows each formula in the app. It is an interpretation aid: it does not calibrate instruments and does not certify links. PRIVATE BY DESIGN No accounts, analytics, advertising or tracking. Traces stay on your device until you export or share them yourself.
