The Intellisnap feature allows any snap point to be used as an orthogonal reference point. It can be used as an alternative to creating construction lines. Basically Draft it remembers all points browsed over with the cursor. When the cursor is moved around Draft it displays a dotted line to any 'remembered' point either horizontally or vertically from the current cursor position.
To find out more about how to use this feature see Intellisnap in the How To section.
