A graphic attribute manager which governs how objects such as color, width, line thickness and deflection are displayed. Prs3d_Drawer is the mother class of AIS_Drawer. As such, it is its set functions which are called to modify display parameters. In the example below we can see that the AIS_Drawer is modified to set the value of the deviation coefficient using a method inherited from Prs3d_Drawer. A drawer includes an instance of the Aspect classes with particular default values.
