Drawing Exercises
Exercise 1: Drawing an Unrolled Truncated Cone
The purpose of this exercise is to gain a better understanding of descriptive geometry, projection techniques, and developable surfaces, while learning and developing two-dimensional digital drafting tools and skills.
This drawing composition consists of five projections of a truncated cone: a top view (plan), front view (elevation), side view (elevation), a view of the unrolled (developable) surface of the cone, and an auxiliary view (“true” elevation) of the truncated surface of the cone.
To complete this drawing, use Rhino 3D modeling tools to create points, lines, polylines, circles, and curves; replication tools, such as copy, ArrayPolar, and mirror; editing tools, such as trim and extend; and transformation tools, such as move and rotate. Use modeling aids to control the snap and ortho settings. Draft the linework at a 1:1 scale and constrained to the XY CPlane in the Top viewport.
