Line control
Line control is the ability to place marks with chosen pressure, direction, and flow across straight lines, curves, and ellipses.
What it is
Line control means placing a mark where you intend, with the pressure and direction you choose. It supports steady construction lines, straight edges without wobble, and curves without accidental bulges or flattening.
Use it to block in boxes with single strokes, draw smooth arcs around cylinders, and place a head’s center line in one motion. Ellipses, or circles seen in perspective, test control through smooth, closed, aligned marks.
Why it matters
Weak line control can make boxes twist, cylinders kink, and ellipses point incorrectly in space. Controlled strokes keep construction forms readable and reduce repeated line corrections.
You can check it when
- ✓Draw a straight line between 2 points in one motion. Check whether it reaches both endpoints with minor wobble and without repeated strokes.
- ✓Review curves, S-curves, and ellipses at a smaller size. Check for smooth flow, closed shapes, and unwanted flat spots, bulges, kinks, or short segments.
