You can add a GMask preset node to the schematic. Two preset nodes are available: Ellipse and Rectangle.

To add either a GMask Ellipse or Rectangle node:

1. Do one of the following:
   • Drag the GMask preset node from the node bin and place it in the Schematic view.
   • Drag the GMask preset node from the node bin and place it in Result view.
   • Double-click the GMask preset node.

A GMask object (called gmask1, by default), with its parent axis, appears in the Schematic view. Once the GMask preset node has been created, it will have the same functionality and settings as a normal GMask node and can therefor be manipulated in the same ways. When a GMask has been finished, the user can still make shape transformations to the mask by clicking the Edit Box button.
