Creating Axis Lines and Center Lines

	This task will show you how to create simultaneously axis and center lines on several circles.
	Open the Brackets_views02.CATDrawing document.
	Click the drawing window, and click the `Axis Line and Center Line` icon from the `Dress-up` toolbar (`Axis and Threads` sub-toolbar).

	Select two circles.

	The axes and center lines are created.

	Select an axis line manipulator and drag it along a direction. You can notice that thread axis lines are modified symmetrically.
	If you want to move only one axis line, hold on the Ctrl key while you are dragging the manipulator.
	When creating axes and center lines in a Generative Drafting context, a message will be displayed if axes and center line cannot be associative to the 3D.
