Intermediate Example: Isometric Circles Draw a circle on an isometric plane.

Advanced Example: Non-Isometric Lines Draw a sloped roof.

Basic Example: Cavalier vs Cabinet A $100\text{mm}$ deep object.

Intermediate Example: Choosing Front Face Drawing a cylinder with complex face features.

Advanced Example: Angle of Receding Axis Choosing depth angle.
