Smart edge snapping

When smart edge snapping is on, the SmartCursor finds points on, or at a certain distance away from, a specified edge. The edges of linear 2D geometry, arc and polyline curve segments, and 3D segments and curves, can be acquired as smart edges. Once a smart edge has been defined, you can align to it horizontally, vertically, or at a specific angle using extension lines and SmartCursor cues. A smart edge also provides snapping to a point on an edge without having to activate Nearest Point on Edge object snapping.

To set a smart edge, slowly move the cursor over a 2D object edge for the set number of seconds, or press the T key while over an edge. Dotted extension lines indicate that the smart edge has been set.

Up to two smart edges can be set, and then the oldest edges are replaced. A smart edge can be released by moving the cursor slowly over the edge or pressing the T key over the edge again.

2. To change settings, if needed, double-click the tool, or select Tools > SmartCursor Settings.

The SmartCursor Settings dialog box opens. From the Smart Edge tab, specify the smart edge snap settings.

Parameter	Description
Acquire Edge	Sets a smart edge at the cursor location when the cursor moves over an object edge for the indicated number of seconds. Alternatively, press the T key to set or release a smart edge at the cursor location, even if the Acquire Edge option is disabled.
Snap to Bisector	Finds points along the bisector that intersects two smart edges
Snap to Offset	Sets an offset from either end of a smart edge extension line that is indicated by additional markers along the extension line; enter the offset value
Snap to Extension Lines	Generates extension lines from smart points perpendicular and parallel to the smart edge
