# The Main Window

The main window is divided into three parts: the left panel is the hierarchy browser which depicts the cell hierarchy. Cell nodes can be expanded showing the child nodes. The cell selected in the cell browser is shown in the center panel.

The center panel is the actual canvas. There, the layout is drawn. Click there to zoom or to draw rulers for measuring distances.

The right panel is showing the layer list with the layer drawing style. Below a set of control panels is located. The control panels are minimized per default. They can be expanded by clicking on the header bar.

Several control panels are available allowing to control colors, fill and drawing styles etc. Select one or many layers in the layer list to apply the selections from the control panels to.

Multiple layouts can be shown at once. Either they can be overlayed or they can be shown in separate views. In this case, a tab panel appears at top of the main window. Switch between the views by selecting the tab.
