The Solid fill style option is located in the bottom of the Fill Window. This attribute sets the fill of a selected or any created figure(s) to a solid color and can be accessed in one of the following ways:
Press on the Fill Button located in the Drawing Toolbar.
Press on the Info Button in the Top Toolbar.
Then tap on the Fill option to open the popover window shown below.
The Fill option must be enabled for a style change to be applied to any currently selected or new figures. Tap on the On/Off toggle slider in the upper right hand corner of the Fill Window to enable this option. The slider will appear with a green background when this option is enabled.
To change the Fill Type to solid:
Press on the Solid Button at the bottom of the Fill Window (if not already selected).
Note: A style change will be seen instantaneously when a figure is selected. If figures have not been selected, the style change will apply to all subsequently created figures.
