These videos show you how to sketch simple shapes in two-point perspective. I use a Wacom Intuos graphics tablet with Autodesk Sketchbook, but you can also follow them all using conventional, paper-based sketching techniques.
Start with the introductory video shown right. This will give you an idea of how to work with perspective.
To be able to draw in two point perspective, it's really important that you know how to draw a circle in 3D: drawing ellipses. These videos lead on nicely to the Apple TV Remote below.
Like with the one point perspective tutorials, the videos below show you how to transfer the theory (above) into practice of product design sketching.
The activities on this page are intended to teach you how two-point perspective works and what the difference is between it and one-point.
When you've finished drawing the train car concept on the top right, have a go at using your pen to render it using cross-hatching.
Shown below are some more exercises that you can follow that are in both one and two point perspective
