Power Snap Settings Dialog Box (AutoCAD Mechanical Toolset)

Use the Snap Settings dialog box to create four global settings, or four global settings and one current setting, for the object snaps.

Power Snap Configuration Displays a drop-down list of a current setting and four global settings.
Power Snap tab
	Object Snap On Turns object snap on and off. Whenever AutoCAD Mechanical toolset prompts you to pick a point, and object snap is on, as you move the cross hairs in the vicinity of a point selected under Modes below, the cross hairs snap to it. Additionally, AutoCAD Mechanical toolset displays a marker and a tooltip at the snap location. You can also turn Object Snap on or off by pressing F3.
	Object Snap Tracking On Turns object snap tracking on and off. With object snap tracking, the cursor can track along alignment paths based on other object snap points when specifying points in a command. To use object snap tracking, turn on one or more object snaps. The AUTOSNAP system variable controls this setting.
	Snap On Turns Snap mode on and off. When you turn snap on, the cursor “snaps” to a grid that divides the drawing area into small rectangles. You can also turn Snap mode on or off by clicking Snap on the Status bar, by pressing F9, or by using the SNAPMODE system variable.
	Modes
		Endpoint Snaps to the closest endpoint of an object. (END)
		Midpoint Snaps to the midpoint of an object. (MID)
		Center Snaps to the center of an arc, circle, ellipse, or elliptical arc. (CEN)
		Node Snaps to a point object. (NOD)
		Quadrant Snaps to a quadrant point of an arc or a circle. (QUA)
		Intersection Snaps to the intersection of a line, an arc, or a circle. (INT)
		Extension Snaps to the phantom extension of an arc or line. (EXT)
		Insertion Snaps to the insertion point of text, a block, a shape, or an attribute. (INS) or the base point of a (mechanical structure) component view or folder. (INSS)
		Perpendicular Snaps to a point perpendicular to an arc, a line, or a circle. (PER)
		Tangent Snaps to the tangent of an arc or a circle. (TAN)
		Nearest Snaps to the nearest point of an arc, a circle, a line, or a point. (NEA)
		Apparent Intersection Snaps to the apparent intersection of two objects. (APPINT)
		Parallel Snaps parallel to a specified line. (PAR)
		Arc Radial Lines Snaps to a point on the phantom line that passes through an arc center point and one of the arc endpoints. (ARCR)
		Arc Tangent Lines Snaps to a point on the phantom line that passes tangentially through an arc endpoint. (ARCT)
		Symmetry Snaps symmetrically to a specified line. (SYMP)
		Select All Selects all object snap modes on the respective Setting tab.
		Clear All Clears all selected object snap modes on the respective Setting tab.
	Options
		Crosshair Size Defines the size of the crosshairs.
		Show Snap in Status Line Displays the currently active snap modes in the status bar.
		Ignore Z Coordinate Sets the Z coordinate to 0.0. The program projects all points selected on the current coordinate system.
		Use Entity Filter Activates the current settings in the Entity Filter dialog box.
Polar Snap tab
	Polar Tracking On Turns polar tracking on and off. You can also turn polar tracking on or off by pressing F10 or by using the AutoCAD AUTOSNAP system variable.
	Polar Angle Settings Sets the alignment angles for polar tracking. The POLARANG system variable controls alignment angles.
		Increment Angle Sets the polar increment angle used to open polar tracking alignment paths. Enter any angle, or select a common angle of 90, 60, 45, 30, 22.5, 18, 15, 10, and 5 degrees from the list. The POLARANG system variable controls this setting.
		Additional Angles Makes any additional increment in the list available for polar tracking. The POLARMODE system variable controls the setting. If selected, the box below this title lists the additional angles that are available.
		New Displays the Additional Angle dialog box enabling you to enter new angles.
		Delete Deletes selected additional angles.
	Object Snap Tracking Settings Sets options for object snap tracking.
		Track Orthogonally Only Displays only orthogonal (horizontal/vertical) object snap tracking paths for acquired object snap points when object snap tracking is on. The POLARMODE system variable controls this setting.
		Track Using All Polar Angle Settings Enables the cursor to track along any polar angle tracking path for acquired Osnap points when Object snap tracking is on while specifying points. The POLARMODE system variable controls this setting.
	Polar Angle Measurement Sets the basis by which the program measures polar tracking alignment angles.
		Absolute Bases polar tracking angles on the current user coordinate system (UCS).
		Relative to Last Segment Bases polar tracking angles on the last object you created.
	Polar Snap
		Polar Snap On Sets the snap type to PolarSnap. When you set the snap type to Polar Snap and Snap mode is on, the cursor snaps along polar alignment angles set on the Polar Tracking tab relative to the starting polar tracking point. The SNAPTYPE system variable controls the snap type.
		Polar Distance Sets the snap increment distance when you set the Snap Type to Polar Snap. If this value is 0, the Polar Snap distance assumes the value for Snap X Spacing. The POLARDIST system variable controls this value.
Filter Options Displays the Entity Filter dialog box.
