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).
Oil painting Although surfaces like linoleum, wooden panel, paper, slate, pressed wood, Masonite, and cardboard have been used, the most popular surface since the 16th century has been canvas, although many artists used panel through the 17th century and beyond. Panel is more expensive, heavier, harder to transport, and prone to warp or split in poor conditions. For fine detail, however, the absolute solidity of a wooden panel has an advantage.
