>The mechanical skills of wielding a pencil or mixing paint are almost trivial

I strongly disagree. Try drawing a large shape without using a template. If you move the pencil with your fingers, you quickly run out of range of motion, and have to reposition your hand and join the new line segment without visible discontinuity, which requires extreme accuracy[0]. If you move it mostly with your arm then you have to learn the difficult and unnatural skill of fine motor control using large muscles. In practice the only good option is using a combination of both, which requires great coordination. The visual part is easy after you learn a few simple tricks like looking at negative space. The mechanical skills are the difficult part.

Completely untrained people can trace a drawing with a good degree of accuracy, yet fail completely to draw even simple forms with any degree of verisimilitude.

Teachers like Betty Edwards and Bert Dodson have proven that pretty much anyone can learn to draw to a high standard in a remarkably short space of time once they understand the visual principles of effective drawing. Mastering draftsmanship requires a lifetime of practice, but competence can be achieved in a matter of days with the right instruction.

I always felt this was an argument against what you are saying. Tracing doesn't require much fine motor control because you can rest your hand on the paper and go over the existing image with very small strokes.

For example, try drawing the simplest of all forms: a straight line. I always found that good drawers can draw an incredibly straight line, freehand. My "straight" lines look like I was standing on a boat in rough seas. Yet certainly visualizing the properties of a straight line seems very simple to me. Even, for example, drawing a straight line smoothly between two other lines on a piece of filler paper is something that a good drawer could do much better than I.

> try drawing the simplest of all forms: a straight line

My high school algebra/geometry teacher, Fr. Arnold Perham, taught me this crucial skill almost 30 years ago and I use it frequently still and teach my own students how to do it. The trick: put your chalk/pencil/marker at the start of the segment; then look at the other end of the segment and keep your eyes there; and then draw the line. It's like magic.

Huh, this sounds strongly related to target fixation. Look at your target and your body 'knows' how to go there (or throw there, or...)

The classic example is if you're riding a motorbike and you start worrying that you're going to run wide, or hit a tree, or whatever, so you start staring at the side of the road, or the tree... and that's where you go.

Also in tennis: look there the ball should go, not at it as you hit it.

Drawing requires exactly the same motor skills as tracing, except that the thing you're tracing isn't there yet.

Only if you can track your absolute position with exceptional accuracy.

I know a lot of artists that talk about the importance of learning how to better draw longer lines in one go. Are you saying they're all wrong, and that skill isn't important?

Draftsmanship is quickly learned by young people. I sat next to a 20 year old at Boeing who was very competent at making engineering drawings (and Boeing had high standards - they didn't want any ambiguity for obvious reasons). Though perhaps you mean something else by draftsmanship.

draftsmanship (noun)

1) the art or craft of a draftsman

2) the skill of drawing

Draftsmanship refers to both technical and artistic drawing skill.

Come on, mechanical drawing and 'artistic' drawing are totally different skills. The best technicians, with the highest level of mechanical drawing training and experience, wouldn't be able to draw a portrait.

RISD asks applicants to draw their bike as part of the application. It's tough because both originality and observational skills are needed (google "risd bike").

But OMG it is important to realise that being able to make measured, technical drawings is not the same as being a renaissance draftsman, capable of the most incredible evocations of the human body etc.

I'm not saying that they're the same thing, I'm saying that the word "drafting" applies to both. Art history books frequently make reference to the draftsmanship of an artist like Da Vinci or Dürer. The words "draft", "draw" and "drag" have the same etymological root and all three are partial synonyms.

As someone with pretty much zero ability to draw, that caught my attention. What would be "a short space of time"? Are we talking days, months, years?

You can improve your drawing about a thousandfold in the span of a couple minutes by learning to observe things instead of just what you think they look like.

Go grab something as reference material, anything moderately complex will do. Now when you look at this thing, ignore what it is or even what three dimensional shape it has. Look for edges. The edge between the background and the object, The edges internal to the object. Look for the position of these features relative to the others. Keep doing this while you draw exactly what you see. Resist the temptation to draw without looking at what it actually looks like.

Of course once you've managed to look at things properly you'll still need tons of practice with drawing, but just doing this is going to stop you from drawing pictograms instead of pictures.

I'm a terrible artist, not even a doodler, but I remember one time sitting in a long boring meeting where I stared at the profile of someone's face and carefully drew it with amazing accuracy (relative to my utter non-ability, not relative to a good sketch artist)
It depends. Drawing and programming share some aspects. You can do a short program in "oil painting language" easily, but it takes years to master the media.

You need to keep the focus on it for a long time and build it in small steps. A telephone or somebody breaking in the room and your work could be permanently damaged and you will need a lot of effort to keep the focus again. Sometimes the image just "dies" in the way of being painted.

Painting is often done in imperative style and can be a painful, demanding and really tiresome work. Some people underestimate the effort needed to do it right. You need to "declare" all your tones in advance, fill the shadows and keep in mind a rigid frame to place it. If you do it in several sessions you will need to obtain the same exact tone again (or have a plan B in advance), so you'll need to make a lof ot comments and document your work.

And there are bugs. You will find a lot of bugs in the process and will need to fix it in a short time. Some mediums dry fast and crack easily. Different pigments spread in different ways. Some tones are notoriously complex to obtain also (realistic 3D gold for example) and you can't learn the right way in a week. The eyes of your public have evolved to detect abnormal tones for good reasons (would denote diseases or people faking emotions so is survival relevant). A skin too pale or with a greenish tone or a slight curve in the rictus and your picture can enter in autopilot mode or just sink.

Sometimes the painting turns in a such mess that you just trown the code away and start again.

Automatic drawing is drawing in functional style and is a totally different creature.
