# Creating Global Variables and Equations

Global variables and equations are created via the Feature Modeling Global Variables dialog, which has tabs for Variables and Equations. This lets you Create, Edit, and Delete variables and equations as well as Apply edited values to any solid(s) that uses the global variable. When you create a variable, it can be one of the following Types:

- Distance — (the default) defined in working units and displayed as specified in the Working Units category of the Design File Settings dialog ( ).
- Degrees — defined in degrees and displayed as specified in the Working Units category of the Design File Settings dialog. When using trigonometric functions, the Angle variables of type Degree are computed without conversion to Radians. If you wish to use Radians with the trigonometric functions, then the variables should be of type Number.
- Number — a floating point number with six digit precision.
