The Keypoint snap mode is often the most useful snap mode for drafting operations. This is because the Keypoint snap mode snaps to an element’s nearest “keypoint.” A keypoint can be a variety of snap locations such as endpoints, midpoints, vertices, center, etc. depending on the type of element that is to be snapped to.
Common elements and their respective keypoints include:
– Lines, Line Strings – Endpoints, Vertices
– Arcs – Endpoints, Quadrants, Center
– Circles, Ellipses – Ends of Axes, Quadrants, Center
– Cells – Keypoints of Component Elements
– Curves – Projections along Curve
– Shapes – Vertices
– Text, Text Nodes – Justification Point (Left Top, Center Center, etc.)
A powerful feature that the Key Point snap mode has is the Snap Divisor. This divisor subdivides an element’s snap locations into equal segments.
For example, snapping to a line when the Snap Divisor is set to 1 will have two available snap locations, the two end points, thus the element’s snap location is divided into 1 segment. Snapping a line when the Snap Divisor is set to 2 will have three available snap locations, thus the element’s snap location is divided into 2 equal segments.
Setting the Snap Divisor:
The Snap Divisor settings can be accessed from the Snap section of the Locks dialog box (Settings > Locks > Full).
Using the key-in browser dialog, type: KY=2
AccuDraw Shortcut “K” will open the Keypoint Divisor dialog where the user can either type a value or select a number from the drop down list.
