There are lots of lessons on how to draw linear perspective, be it 1-pt, 2-pt or even 5-pt.
But I have NOT seen any that have dealt with drawing curves, circles or cylinders in 3D.
So, here is how you do it. Based on the standard 1-pt. perspective model, by extension
this is what a circle ought to look like when done with mechanical linear perspective.
The degree of thinking and precision for this lesson merits Grade 6 or higher, says I.
