drawing board
a term that describes the relative 'weight' - strength, heaviness, or darkness - of the line against the background or support. It is governed by the pressure on your drawing tool as you make your line - whether this is decreasing or increasing the pressure on the tip so that it leaves behind more or less medium - or altering the angle so that more of the tip is in contact with the paper.
Lineweight
A measurement that numerically defines the size and location of sketch geometry, such as the length of a line, diameter of a circle, or radius of an arc. Specifications of the size and shape of object features so that parts can be manufactured; along with notes and other text, also specify the location and characteristics of geometry and surface texture.
