I did some more work on the drawing for the new pipe wrench study. The extreme foreshortening presents real challenges, making it important to understand the wrench’s complicated geometry. Even though the wrench is an engineered object, few of its edges and surfaces are parallel. This means that the image has multiple vanishing points.

The extreme foreshortening also wreaks havoc with cylinders and circles. In the picture below, I’ve fixed some of the issues with the linear gear perspective, but I still need to work on the knurled adjustment wheel.
