## What is ConeCalc?

A calculator for the flat pattern dimensions of a cone. For creating a cone from sheet metal or any flat material. 

Enter the desired dimensions of the finished cone shape. You only need to enter one diameter and two other of the five possible dimensions of the final cone. The other dimensions will be calculated from these.

A drawing of the flat pattern with dimensions is produced. Also calculates number of cones that can be cut from a sheet size.

## Key features

- Flat pattern dimension calculation
- Cone creation from sheet metal
- Input desired cone dimensions
- Generate flat pattern drawing
- Calculate cones per sheet size

### 5/5 — Cool tool

*2024-03-10, version 1.2.0*

Every now and then you have to make reducer in the field, this app would of been helpful a few weeks ago to figure out the math on the fly. 
Looking forward to to next time.

### 5/5 — Works great!

*2021-12-29, version 1.2.0*

In developing a stove hood that uses cones this application helped out.  It’s right!  Thanks.  PS: note the big calculate button up top.

### 5/5 — Worked great until I got a new phone.

*2020-07-13, version 1.1.0*

Just got the iPhone 11 Pro.  I can’t get the calculate button to work.  If you see this can you look into it.  This app makes life easy when I can use it.

### 4/5 — Fantastic and easy to use app but...

*2019-12-13*

I have used this quite a few times with excellent results, but the issue I have had is that on the new iPhones, hitting the “Calculate” button is extremely difficult to do, almost impossible. If this was updated, 5 stars

### 1/5 — Garbage

*2019-06-21*

Doesn’t work on my iPhone X because the calculate button is covered by the ear mic. Therefore not able to calculate anything. Needs update bad!!

### 1/5 — Calculate button obscured on iPhone XR

*2019-02-21, version 1.1.0*

Won't work with an iPhone XR as the calculate button is obscured by the phones earpiece

### 5/5 — Fabricator

*2013-12-28, version 1.0.0*

This app is easy to use and incredibly useful for a quick and easy layout of concentric cones for the metal fabricating industry. It even has a built-in plate optimizer so you can tell how many parts you can get out of a user-definable sheet size. Well-done.

### 3/5 — Mean diameter

*2013-11-27, version 1.0.0*

This app would be more accurate if there was the option of using the mean diameters I.e. centre lines on the thickness of the material. I make cones on a regular basis and flat patterns must be calculated using the mean diameters to achieve the correct finished size.
