Selection Sensitivity When on, using the Orbit tool on page 127 rotates the view around the current selection, rather than a predefined center. Strokes Customize menu > Preferences > Preference Settings dialog > Viewports tab > Mouse Control group > Stroke Strokes are a way to assign command shortcuts to mouse or tablet drag patterns. For many operations, strokes are more convenient than keyboard shortcuts because they can select an object and apply a command to it. For example, you can assign Orbit to a downward stroke. When you draw this stroke, the software changes to Orbit mode. You can assign a circular stroke to the Hide Selected command so that it both selects the objects and then hides all the objects in the bounding extents of the stroke pattern. You can use strokes in two ways: ■ If you have a middle mouse button, you can define and use strokes by specifying the Stroke option for the middle mouse button in the Viewports tab on page 7753 of the Customize menu > Preferences dialog. ■ To define and use strokes with the left mouse button, use the Strokes utility on page 7854 and turn on Draw Strokes. Using the Keyboard with Strokes The same stroke pattern can perform four different functions by holding Shift, Alt, or Shift+Alt when drawing the stroke: ■ Drawing a vertical line is one type of stroke. ■ Holding Shift while drawing the same line is another type. ■ Holding Alt while drawing it is a third type. ■ Holding both Shift and Alt while drawing the line is a fourth type. Holding Ctrl while drawing a stroke indicates that you want to define a new stroke, rather than use an existing stroke. NOTE Changes you make to the set of strokes are saved with 3ds Max and persist from session to session. 7842 | Chapter 26 Customizing the User Interface
