Randal created this concept car illustration in Adobe Illustrator using a Apple Macintosh and Wacom tablet. It is what it is.

4 Cylinder Engine Cutaway
Randal created this cutaway technical illustration of a 4-cylinder automotive engine as a self promotion piece for use in advertising his technical illustration skills in the 1980′s. This illustration was done by hand with Rapidograph ink pens on smooth illustration board.
Cartoon Car
Randal sketched this cartoon car in his sketchbook during an airplane ride from Chicago to Denver. It was done analog… pencil on sketchbook paper… then scanned and imported on a Mac and saved with Adobe Photoshop.
Interestingly, a young man named Ani recently contacted him from California and asked if he could use this sketch on the website he is building. He said, “Yes!”
Bob Sharp Racing Datsun
Randal enjoys automotive illustration, especially of racing and hot rod automobiles. This illustration is of a 1972 Datsun 240z racing car modified and driven by Bob Sharp Racing team in the IMSA circuit. These early Datsun’s (now Nissan) were very popular in the early 1970′s, and Randal owned and restored one himself.
Nascar Sketch for IBM
Sometimes the early quick sketch or design study turns out better than the final art! This pencil sketch was done by Randal in preparation for an illustration for an IBM publication that featured information about the company’s AS400 product line. The number “64″ on the roof also had significance because the AS400 was being offered in a 64-bit model. Of course this makes the computer faster… hence the race car theme.
The quick loose lines and conceptual working out of the idea has a certain quality that is lost in many final illustrations. This was done with pencil on tracing paper. I always preferred this sketch version over the final pen and ink art!
Mercedes Benz Protoype C-111 Gullwing
Randal did this drawing of a Mercedez Benz Prototype Model C-111 in the 1980′s. Based upon a photo of this experimental, Wankel-powered automobile, the illustration was done by hand with ink lines and black wax pencil shading on croquill board. Croquill board has a bumpy surface that when certain types of dark pencils are rubbed across, it creates a “stipple” effect.
Exploded View Diagram
Exploded View Diagram of Automotive Engine Head
Exploded view diagrams are very useful for communicating technical information is an easy to understand manner. They show various parts and pieces of a manufactured item or product in a “pulled apart” manner, with lines and visual aids to help the viewer understand where each part fits, and sometimes even in what order. In this case, an engine head is shown with the gasket, and various pins, washers, springs, seals and plugs extended away and in line with where they fit.
This particular technical exploded view diagram is done in a “pen and ink” style, and can easily be replicated in a vector-based software program like Adobe Illustrator.
