For an illustration, I want to draw a closed cylindrical "can" -- a
cylinder with its axis vertical -- along with arrows (with labels)
indicating radius and height.
The ways I've found, either using Graphics`Shapes`Cylinder or
ParametricPlot3D, insist on drawing curves on the vertical wall of the
cylinder and, if I use ParametricPlot3D to draw the top, too, on the top.
Is there some way to suppress these curves? Of course I still need the
circles bounding the top and bottom to be drawn as well as two vertical
lines that demarcate the wall of the cylinder from the ambient space. I
just want to rely upon lighting and shading to suggest the
Here's my effort so far using DrawGraphics:
