Describe the procedure involved in sketching curved entities such as arcs and circles.
What will be an ideal response?
When sketching arcs and circles, use lightly sketched square bounding boxes to define the limits of the curved entities and then construct the curved entities as tangent to the edges of the bounding box. For example, to sketch a circle, you first lightly sketch a square (with straight lines). Note that the length of the sides of the bounding box is equal to the diameter of the circle you are attempting to sketch.
