I'm drawing a building and a part of it cylindrical and all covered with colored glass sheets, and i don't know how to show all that together: that it's glass, colored and cylindrical, so if anyone has any idea I'd be thankful :)
Shade that section as if it WERE a cylindar. Even glass panes look different in the shade than those sections that are in full sunlight. If your elevation is rendered in color, you can add gradiated touches of light blue to darker blue to indicate the curvature of the section. If it's black and white, then use greys. It it is strictly a line drawing then darker and more numerous streaks of black lines can create the shaded effect.
