Hi. Im Doug Patt and this is How to draw with lead. Today Ill be creating an abstract pencil rendering of machine parts. Ill be using a .5mm Pentel mechanical pencil with HB leads. You can also use a slightly larger diameter lead with a .7mm pencil, but I like the thinner line. The other type of pencil you may choose is a lead holder drafting pencil. These are a little trickier because youve got to keep them sharpened. Ill also be using 4 different lead pencils. These are all Staedtler Mars Lumograph pencils. Theres the 2h the lightest and hardest I will be using, an HB which is the typical hardness on most pencils, and a 2b and 4b both progressively softer and darker. Ill be using a small sized adjustable triangle, a ruler and drafting tape. I also have some templates I really like to use as well as a compass, an electric eraser and metal eraser shield. So, Ive cut out a small rectangular piece of Strathmore 400 series drawing paper. This paper is a little thin for my taste, but it has a nice texture and its acid free so it should have a nice lifespan. Im a classically trained artist so I like to use the golden section and the root rectangles as the drawn armature on my page. I do this in to help me organize and develop my drawing but thats for another episode. The piece of paper is the same proportion as a rootphi rectangle. Now, I love machines and I really enjoy drawing abstractions of them. So I chose these three machines I saw at our local fair this summer. Im going to take visual cues from the various parts of the machines and redraw them on the page organizing them relative to the armature of my rootphi rectangle. Im choosing the machine parts and their location on the page in a subjective manner keeping in mind that the drawing should have a dominant direction in order to make the composition more dynamic. The drawing is made by using the .5mm mechanical pencil to lightly draw out the basic forms. Then I simply add line weight and detail with my Staedtler HB pencil. I like to think about these compositions as sections through machinery like an engine. For this reason Ill typically give the exterior forms a kind of casing that appears in poche. Now, I like to render my drawings by constantly adding layers. These layers are made by a series of hatched horizontal rows. The row dimension varies depending upon the size of the rendering but its typically about 1/2. Once the drawing has been filled with rows of rendering I will spin the drawing 90º and repeat. This process is repeated over and over again until the proper value for a specific location is achieved. The more layers of rendering you do the deeper the shape becomes and the further away it appears. The object of this drawing is to create the appearance of a 3 dimensional abstract object. You can also add shade and shadow to enhance the appearance of depth by making a series of lines against your straight edge or triangle. Finally, I like to scan the drawing in any number of graphics programs and add more depth and better contrast. So there you have it. An abstract rendering of farm equipment machinery parts and few tips on drawing with lead. So, thanks for checking out How to draw with lead. See you next time.
