# Creation tools: coordinate system

## Coordinate system

The Flux sketcher uses coordinates systems in the same way as Flux. The creation of a coordinate system remains unchanged and is done as it is in the Flux geometry interface.

The description of geometry requires specifying the working coordinate system with the possibility of having several coordinate systems. In the sketcher, all the description is done automatically. The coordinate system taken into consideration during a creation is the activated coordinate system.

The choice of the active coordinate system is done by means of a group listing the available coordinate systems.

## List of coordinate systems

The list of coordinate systems is placed bottom left under the graphic window.

## Selection of coordinate systems

The coordinate systems can be selected via :

- the list
- the graph
- the data tree

The selected coordinate system will appear highlighted, while the others remain black.
