The Grid Lines and Levels toolbar

In the Lines toolbar you can switch on/off the grid lines that have been previously set up for the frame. The grid lines can also be set to thicker lines if required. The grid line bubbles colour can be inverted to make them clearer in some instances. You can also draw grid lines that are outside the current view if you have a partial frame view displayed. This can be particularly useful when creating a model and adding new members around the periphery of the current partial view. You also have the option to alter the test size.

The level numbers can also be displayed on the frame members.
