 There are two kinds of targets you can use to align objects. The Snap Target (yellow arrow), and the Snap Source (green arrow). Use the Snap Target to mark a position in the scene to which you want another object moved or aligned. Use the Snap Source to specify a particular point on the selection to move to the Snap Target.

 ### Layout Tools
 
 The Grid and Angle layout tools work essentially the same way; they provide regularly-spaced reference points for the Snap Target. When you place the target (or source) marker on a construction tool, it snaps to the reference points of the tool. For the Grid, these points are the intersection of the two perpendicular sets of lines. For the Angle tool, these points are the intersections of the rings with the spokes.
