Object Snapping

When snap to object is on, the SmartCursor finds specific parts of an object, such as corners, endpoints, midpoints, or centers of 2D objects and arc edges, as well as meshes, extrudes, sweeps, spheres, 3D polygons, 3D planar faces, and walls, floors, roofs, roof faces, loci, and columns. Cues display near the cursor to identify the location.

To set object snapping:

1. Select Tools > SmartCursor Settings, or double-click the Snap to Object tool in the Snapping palette.

The SmartCursor Settings dialog box opens. From the Object tab, specify the object snap settings.

►    Click to show/hide the parameters.

Parameter	Description
End Point	Finds the endpoint of arcs, and the end of an object’s edge
Mid Point of Edge	Finds the middle of the edge of an object
Center Point	Locates the center of 2D objects and arc edges, as well as meshes, extrudes, sweeps, spheres, 3D polygons, 3D planar faces, and walls, floors, roofs, roof faces, loci, and columns
Quadrant Points	Finds the top, left, right, and bottom of circles, ovals, rectangles, and rounded rectangles
Insertion Point	Locates the object origin of loci, lights, objects, symbols, text, and for dimensions, one of the referenced points
Vertex	Locates the corner point on polyline, polyline Bézier, and polyline cubic segments; for 3D, finds the vertex of a solid or the control point of a NURBS curve
Nearest Point on Edge	For 2D, finds the closest point on an object’s edge, and for 3D, finds any non-specific point along a solid edge or NURBS curve. It may be more convenient to use smart edge snapping instead; see Smart Edge Snapping.
Master Snap Points	Enables priority snapping for objects, which is useful in congested areas of the drawing, or for certain operations like dimensioning or moving objects, when there are many object snap points within the snap box. The SmartCursor snaps to the master snap point defined for the object, above all other object snap points. See Concept: Snapping Indicators for more details. Master snap points display with a filled red square by default; this can be changed when Configuring Interactive Display.

2. Click OK to set the object snapping options.

3. To activate object snapping, click the Snap to Object tool from the Snapping palette.
