Lesson 7: Applying Construction to Vehicles
As the topics pertinent to this lesson tend to get pretty complicated, there are a couple video demos covering some especially important topics. I do recommend that you read the notes on the first page of this lesson before watching these videos, as they'll help prepare you for some of the topics I cover here.
Ellipses in planes
Not every ellipse we draw will inherently represent a circle in 3D space. When you're drawing them as a part of a larger construction, you have a lot of other elements with which you must remain consistent. This video goes over the criteria that determines whether an ellipse represents a proper circle, when compared against a set of vanishing points.
Constructing to scale
While Drawabox generally deals with the "good enough" school of approximation, there are cases where knowing how to construct an object to a specific scale is very useful. In this case we're still going to apply some approximation techniques, but this is still probably the most technical we ever get.
