## Equation Driven Curves Overview

This Fusion360™ addin creates 3D curves from user-supplied mathematical expressions in the current sketch.

The user may specify parameterized curves in Cartesian, spherical, or cylindrical coordinates.

To open the add-in window, choose Equation Driven Curve, which can be found under the 'Sketch' -> 'Create' menu in the Design workspace. Note that a sketch must be active for this menu to be accessible.

## Examples

### Archimedes' spiral (in Cartesian coordinates)

### Archimedes' spiral (in cylindrical coordinates)

### Helix

### Cycloid

### Conical spiral

### Spherical spiral

## Equation support

As coordinates are functions of `t`

, you can assume this variable exists regardless of coordinate system. For your convenience, the predefined constant `pi`

is also available (you can see it used in several examples above). Be aware that equation interpretation is case-sensitive.

You can find a list of built-in functions here.
