> 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.

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.

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?
