FUNCTION KEYS

DYN = Dynamic Input – (F12) …To have all command line entries on screen near the

pointer.

SNAP = Snap Mode – (F9) …To restrict the movement of pointer in both ‘x’ & ‘y’

direction.

GRID = Grid Display – (F7) …To display grid (i.e. something like graph sheet)

ORTHO = Ortho Mode – (F8) …To draw straight line in orthogonal direction

OSNAP = Object Snap – (F3) …To locate the point which are listed under snap mode

OTRACK = Object Snap Track – (F11) …To track the located points in orthogonal

direction

POLAR = Polar Tracking – (F10) …To track located points in both orthogonal & non-

orthogonal direction.

NOTE-1 Even though ‘line width’ and line weight are equal to zero by default, both are not

equal.

NOTE-2 OSNAP, OTRACK, POLAR requires the user to be in command mode.

NOTE-3 OTRACK & POLAR must always be utilized with OSNAP.
