## What is Cones Calculator Pro?

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

## Frequently asked questions about Cones Calculator Pro

### What types of cones can Cones Calculator Pro calculate layouts for?

Cones Calculator Pro can calculate flat pattern layouts for full cones, half cones, truncated cones, concentric cones, eccentric cones, and various tori cones with knuckles.

### Is Cones Calculator Pro suitable for industrial fabrication?

Yes, the app is specifically designed for fabrication professionals working with pressure vessels, heat exchangers, and storage tanks, providing ready-to-use fabrication layouts.

### How does Cones Calculator Pro handle large cones that may not fit on standard sheets?

For large cones, the app offers a multi-level option where the cone can be divided into several parts based on height. This allows for easier cutting and subsequent welding.

### What input is required for calculating a truncated cone layout?

To calculate a truncated cone layout, you need to input the cone's small diameter, large diameter, and height. For a full cone, the small diameter can be set to zero.

### Does Cones Calculator Pro offer support for eccentric cones?

Yes, Cones Calculator Pro includes an eccentric cone layout calculator. It uses a 24-part method for development and requires inputs for large diameter, small diameter, and cone height.

### What information is provided in the results page for a truncated cone?

The results page for a truncated cone will provide the development radius, development angle, and development cord lengths, which are essential for fabrication.

### What is the pricing for Cones Calculator Pro?

Cones Calculator Pro is a paid application priced at $3.99.

### What devices is Cones Calculator Pro available on?

Cones Calculator Pro is available for both iPhone and iPad devices.
