The 'Perp' keyboard snap allows a quick and easy way select a 'Perpendicular' point on an existing entity. This snap is only valid therefore if a current point exists i.e. selecting the second point when drawing a line.
To use this feature simply position the cursor over an entity e.g. a line, and hit the key. Draft it now sets this point as the currently selected point at the perpendicular position on the entity. The dynamic line previously attached to the cursor also attaches to this point. If you are happy with the point selected click anywhere in the drawing area to accept.
Alternatively you can hit the key to define a position Relative to this point, or hit or to select the X or Y values of this point.
Use any of the following keyboard snaps ( End, Mid, Perp and Tan) to cancel the point selection if the cursor is in 'free space' or select another point if it is over an entity.
Use of these keyboard snaps also automatically switches to the Snap input mode.
