Creating Threads (Reference)

	This task shows you how to create a thread with a reference, either circular (circle or point) or linear (line). In this particular case, you will apply a thread to a hole with a line as reference.
	Open the Brackets_views06.CATDrawing document.
	1. Click the Drawing window, and click the Thread with Reference icon from the Dressup toolbar (Axis and Threads subtoolbar).
	You can multi-select holes before you enter the command and then apply center lines to the selected holes.
	Activating this command displays two options in the Tools toolbar.
	The `Reference Tap` type option (Tools toolbar) is activated by default. 2. Select the `Reference Thread` type option (Tools toolbar).
	3. Select a reference line. The thread is created according to this reference.
	4. Select a manipulator and drag it along a direction. 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.
