what kind of drawing is used in the making stage
Production drawing Production drawings[1][2][3] (sometimes called working drawings) are complete sets of drawings that detail the manufacturing and assembly of products (as distinct from engineering drawings prepared by and/or for production engineers whose task is to decide how best to manufacture the products).
Encaustic painting Encaustic painting, also known as hot wax painting, involves using heated beeswax to which colored pigments are added. The liquid or paste is then applied to a surface—usually prepared wood, though canvas and other materials are often used. The simplest encaustic mixture can be made from adding pigments to beeswax, but there are several other recipes that can be used—some containing other types of waxes, damar resin, linseed oil, or other ingredients. Pure, powdered pigments can be used, though some mixtures use oil paints or other forms of pigment.[1]
