DS9 hates to draw and his drawings are scribbled and look like a 4 year old might have done them, but if he sees a purpose, then they are more skillful. We were arguing about a math problem and he whipped out a piece of paper and drew a 3D block and shaded the part he wanted to show me. Spatially, he is obviously well aware of what he is doing. He can also draw maps from memory. But if you asked him to draw a cat or person it would look like a 4 year old did it. He just doesn't care, and he has fine motor issues so tries to get out of drawing whenever possible. I don't think a test like this could be used reliably with a child with delayed motor ability or other 2e issues.
