Want to draw an eccentric awl now, underside is on the XY plane of WCS, the centre of a circle (0, 0, 0) , radius 100, apical (300, 0, 400) is on ZX plane.

1) join PA, PB.

A(-100, 0, 0) B(100, 0, 0) pursues 1 fall in current coordinate: 2) lengthens PA to arrive C, make PA=CA; lengthens PB to arrive D, the horny bisector that the halve option in making PB=DB;3) joins CD;4) draws round;5) to command with XLINE for the diameter with CD makes horny CPD PO, hand in CD to cross O to make the vertical line of CD at O;6) , make a circle at E, f; graph 27) is used UCS commanded at 3 o'clock, take was at 3 o'clock: O, p, c; 8) nods O to make the vertical line GO of PO too, hand in PC to be used again at G; graph 39) UCS commanded at 3 o'clock, take was O at 3 o'clock, f, g; 10) can draw elliptical awl now! Cone-e-c- catchs O to nod - catch F to nod - catch G to nod - A- catchs P to nod; graph 411) to return WCS, analyse cuts elliptical awl SL- to choose elliptical awl - carriage return - XY- carriage return - take P place.

12) deletes auxiliary line.
