What is the correct technique for sketching a circle or arc?

Answer 1

To sketch a circle or arc accurately, begin by determining the center point and the desired radius. Use a compass to draw the circle, ensuring the pencil is held upright and the compass point remains fixed at the center. For an arc, place the compass point at the starting point of the arc and rotate it around to mark the desired curve, maintaining a consistent radius throughout. Alternatively, you can use freehand techniques by lightly sketching the outline, refining it for smoothness.
