====== Colour and pattern settings (3D) ======

For most graphics, the colour and pattern can be freely selected. To do this, double-click on the text next to the coloured symbol for the graph in the tree view.

In addition to the **//colour//**, a **//fill pattern//** can be selected. This pattern allows the graphics to appear either fully filled or partially filled, giving them a transparent effect.
 

An additional grid facilitates three-dimensional perception. It can be **//deactivated//**, and its **//colour//** can also be freely selected. 

In the [[3D graphics|settings]] for the graphic, you can specify whether this grid should be optimised for high-speed output (default). These settings work for all fill patterns except **//diamonds (semi-transparent)//**. For technical reasons, the optimised display cannot be used with this pattern; the slow variant is always used here. 

In addition, the graphic as a whole can be drawn translucent by moving the //transparency// slider to the left. The default value for transparency when creating the graphic can be set in the [[3D graphics|settings]].

The example shows the approximate appearance that can be expected later in the graphic display.

**Note**: Some graphics also allow you to change colours and appearance within a list of default values.
