Drafting Tab (Options Dialog Box)

AutoSnap Settings

When the cursor, or aperture box, is on an object, you can press Tab to cycle through all the snap points available for that object.

Marker

Controls the display of the AutoSnap marker. The marker is a geometric symbol that is displayed when the crosshairs move over a snap point. ( AUTOSNAP system variable)

Magnet

Turns the AutoSnap magnet on or off. The magnet is an automatic movement of the crosshairs that locks the crosshairs onto the nearest snap point. (AUTOSNAP system variable)

Display AutoSnap Tooltip

Controls the display of the AutoSnap tooltip. The tooltip is a label that describes which part of the object you are snapping to. (AUTOSNAP system variable)

Display AutoSnap Aperture Box

Turns the display of the AutoSnap aperture box on or off.

( APBOX system variable)

The aperture box is a box that appears inside the crosshairs when you snap to an object.

Colors

Displays the Drawing Window Colors dialog box.

AutoSnap Marker Size

Sets the display size for the AutoSnap marker.

Object Snap Options

Sets running object snap modes.

(OSNAP command)

Ignore Hatch Objects

Specifies whether hatch objects can be snapped to. (OSOPTIONS system variable)

Ignore Dimension Extension Lines

Specifies whether extension lines on dimensions can be snapped to. (OSOPTIONS system variable)

Ignore Negative Z Object Snaps for Dynamic UCS

Not available in AutoCAD LT

Specifies that object snaps ignore geometry with negative Z values during use of a dynamic UCS. (OSOPTIONS system variable)

Replace Z Value with Current Elevation

Not available in AutoCAD LT

Specifies that object snaps ignore the Z-value of the object snap location and use the Z-value of the elevation set for the current UCS.

AutoTrack Settings

Controls the settings that relate to AutoTrack ^™ behavior, which is available when polar tracking or object snap tracking is turned on (see DSETTINGS).

Display Polar Tracking Vector

Displays a vector along specified angles when polar tracking is on. With polar tracking, you can draw lines along angles. Polar angles are 90-degree divisors, such as 45, 30, and 15 degrees. ( TRACKPATH system variable = 2)

In a 3D view, a polar tracking vector parallel to the Z axis of the UCS is also displayed, and the tooltip displays +Z or -Z for the angle depending on the direction along the Z axis.

Display Full-Screen Tracking Vector

Tracking vectors are lines from which you can draw objects at specific angles or in specific relationships to other objects. If this option is selected, alignment vectors are displayed as infinite lines. ( TRACKPATH system variable = 1)

Display AutoTrack Tooltip

Controls the display of the AutoSnap marker, tooltip, and magnet.

( AUTOSNAP system variable)

Alignment Point Acquisition

Automatic

Displays tracking vectors automatically when the aperture moves over an object snap.

Shift to Acquire

Displays tracking vectors when you press Shift and move the aperture over an object snap.

Aperture Size

Sets the display size for the object snap target box, in device independent pixels.

For 4K or higher resolution monitors, the ratio between pixels and device independent pixels (DIPs) is:

Pixel = DIPs*DPI/96

For monitors with lower resolution (100% scaling or 96 DPI), this setting is in pixels.

(APERTURE system variable)

When Display AutoSnap Aperture Box is selected (or when APBOX is set to 1), the aperture box is displayed in the center of the crosshairs when you snap to an object. The aperture size determines how close to a snap point you can be before the magnet locks the aperture box to the snap point. Values range from 1 to 50 pixels.

Drafting Tooltip Appearance

Controls the color, size, and transparency of drafting tooltips.

Settings

Displays the Tooltip Appearance dialog box.

Lights Glyph Settings

Not available in AutoCAD LT

Displays the Light Glyph Appearance dialog box.

Cameras Glyph Settings

Not available in AutoCAD LT

Displays the Camera Glyph Appearance dialog box.
