3D viewing


I’ve a 3D graphics with a series of
x-coordinates in the range : [1.80, 1.81],
y-coordinates in the range : [0.02, 0.03]
z-coordinates , -1 and 1;

Is there any fool - proof formula i can use to make sure the graphics appears on my window???

because I’ve translated the front view to appear on the window and built the remaining faces on that front view …

but i can’t seems to find a correct viewpoint to see the 3D image…

Thanks !
