# 2.12.1 Magnetic Snap

The MagneticSnap feature eases constructing and assembling Tracks and Draw objects by "snapping" the end of new objects to existing objects. For existing track objects the point snapped to is always an open end point. The snap operates when "close" to the object (a few pixels distant) and an anchor point (a blue circle) is displayed when this will occur if the mouse is clicked.

When Adding Draw line objects, the snap point is the nearest point on the existing object. A snap to the end of a line object can be selected by positioning the cursor close to the end of the line but off it, in the direction of the line. This will ensure the closest point is the end.

The MagneticSnap feature is enabled and disabled using either the magnet icon which is part of the SnapGrid Toolbar button set, or using the View (Section 2.12) menu.

For each part of an Add or Move or Rotate operation, the current state of MagneticSnap can be temporarily inverted using the Alt key. This enables snapping to be inhibited for a single part of an operation (or conversely enabled for just one part).
