Snap: Main


Grid Snap: Snap to the grid at the specified x and y values. When grid snap is on, angle snap and object snap are not applied.

Angle Snap: Snap to a specified angle, relative to Last Point. Angle snap may be combined with object snap.

Object Snap: Snap to a specified point on an object. To apply the selected object snap, be sure to click near the object of interest. Object snap may be combined with angle snap.

  • Endpoint: Snap to the endpoints of lines, arcs, and text. Cap Points are also considered endpoints.
  • Midpoint: Snap to the midpoint of a line or arc.
  • Tangent: Snap to the tangent point on a circle, ellipse, or arc.
  • Perpendicular: Snap to the perpendicular point on a circle, ellipse, or arc.
  • Center: Snap to the center of a circle, ellipse, arc, or polygon.
  • Quadrant: Snap to a quadrant point on a circle, ellipse, or arc. Quadrant points are located at 0°, 90°, 180°, and 270° on the shape.
  • Intersection: Snap to the intersection point of two shapes.
  • Nearest: Snap to the nearest point on a shape.

Dynamic Object Snap: Turn on Object Snap and Perpendicular or Tangent Snap. Go into a mode (such as line mode) and click directly on a shape. Then, drag the mouse around and notice how the line that you are drawing stays perpendicular or tangent to the shape. When drawing tangents to a circle, press F6 to reverse the tangent snap direction.

Mutual Object Snap: First, use dynamic object snap to get a dynamic tangent or perpendicular line. Then, click on another shape to trigger mutual object snap. This strategy can be used to create a line that is tangent to two circles (pulley system) or a line that is perpendicular to both a circle and line.

Snap Engine Logic: Snaps are not applied at selection steps. Some method steps are programmed to ignore angle snap and all snaps completely for practical reasons. All keyboard input bypasses the snap engine. Do not let snaps get in the way. Turn them off when needed.
