Art, like morality, consists in drawing the line somewhere. –Gilbert K. Chesterton
We’ve already learned how to make a cube and a sphere—let’s try the other two essential forms: the cylinder and the cone.
Here’s what we’ll be learning about in this lesson:
A cylinder is basically a rectangular cube with rounded edges. It has two round ends connected by straight lines.
A cone is similar to the cylinder, but has a pinched end.
We will be using our two-point perspective for this, so start off by drawing your horizon line and two vanishing points.
The following step-by-step appear courtesy of Brenda Hoddinott for Drawspace.com. Note that she indicates “VP.1” and “VP.2” for the two separate vanishing points.
Establish a vertical line for the front of your cube (I told you they’d come in handy!). We are first going to make a rectangle then we will turn it into a cylinder. Set the vertical lines to mark the ends of your box:
Your completed box should look like this:
Now draw lines from corner to corner on the “lid” and “bottom” of your box to make an X. This will help you find the center of each end of your box. At this point, you can erase the vertical lines marking the edge of your box because they will change when we turn it into a cylinder.
Where these yellow lines intersect with the exterior shape of your box (see red dots) show you where you draw your ellipses (squashed circles found at the ends of cylinders) to turn this box into a cylinder.
The red dots are the points that your ellipse will have to pass through in order to create a cylinder in perspective.
Connect the dots with curved lines, noting that they will not look like perfect circles—they will be pinched and flattened so that they look in perspective.
Now draw in vertical lines attaching the widest parts of the ellipses to each other, like so:
Hurray! You’ve made a cylinder!
Exercise One: Find And Draw Cylinders
Find something in your house that has a cylindrical shape (paper towel roll, candle, hair roller, etc.) and is opaque. Set it up with a single light source and practice drawing free hand your cylinder with value. Move the light source and draw it again. Do this at least four times!
I just photographed some cylindrical objects from around my house and traced some of the ellipses in them so you can see where they are and how different they look depending on the orientation of the object.
Now that you know how to draw a cylinder, a cone will be no problem for you. Start out the same way you would with the cylinder: draw your horizon line, two vanishing points, and three vertical lines to construct the sides of the box. Make your X shape in the bottom of the box and draw lines from your vanishing points through the center and make your ellipse—just like you did with the cylinder.
In the next step, erase the two outside vertical lines (leave the center one) and the lines coming from your vanishing points as well as your horizon line. Then, draw two lines coming from opposite sides of your ellipse ending at the center vertical line.
For the last step, erase your guiding lines, leaving only the cone shape.
Congratulations! You now have a cone!
Exercise Two: Find And Draw Cones
Find an object around your house with a cone shape (ice cream cone, birthday hat, martini glass, etc.) and set it up with a single light source. Practice drawing the cone with your light source coming from different directions each time. Do this at least four times!
When you’ve finished your cylinder and cone drawings, send them to using our submission form!
Key Lesson Learnings : You have learned to draw cylinders and cones using vanishing points, and to find these shapes in objects around you.
