Overview of Power Snaps

Object snaps included with AutoCAD enable you to specify precise locations for objects. AutoCAD Mechanical extends this capability by enabling you to save up to four sets of object snaps and enabling you to switch between them in the middle of a command. The program activates saved object snap settings, referred to as Power Snap settings, when you start the AMPOWERSNAP command.

Power Snaps provide more snap options than AutoCAD Object Snaps. They also give you the ability to set filters so that the system ignores entities such as dimensions, not assigning snap points to them.

Procedures
To change object snap settings
  1. At the Command prompt, enter AMOPTIONS.
  2. In the Options dialog box, select the AM:Preferences tab.
  3. In the AM:Preferences tab, select Snap Defaults.
  4. In the Power Snap Settings dialog box, make the necessary entries and choose OK.
  5. Click OK in all dialog boxes.

Power Snap tab

 

Object Snap On

Turns object snap on and off. Whenever AutoCAD Mechanical 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 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.

Entity Filter dialog box

Use the Entity Filter dialog box to set new filters to object snaps, and to delete or edit existing filters.

Active Entity Filter

Defines if the entity filter settings are derived from the drawing or from the Window’s registry.

When the active entity filter is set to “Registry Settings”, the entity filter settings are persistent across all drawings.

When the active entity filter is set to “Drawing Settings”, each drawing can have its own set of entity filters. This makes it possible to address the special needs of each drawing file, without impacting others.

Delete

Deletes the selected filter.
