Examples of Ionic volutes. From Julien David LeRoy, Les ruines plus beaux des monuments de la Grèce, Paris, 1758 (Plate XX) A volute is a spiral, scroll-like ornament that forms the basis of the Ionic order, found in the capital of the Ionic column. It was later incorporated into Corinthian order and Composite column capitals.
The print shows the shell as 2.5 in (6.4 cm) long, which is probably life size. It appears that Rembrandt copied the shell from life onto the plate, so it is reversed in the print: the printed shell has an anticlockwise or sinistral spiral, but all specimens of this species have clockwise or dextral shells. Rembrandt added his signature and the ...
In shallow drawing, the depth of drawing is less than the smallest dimension of the hole. Bar, tube, and wire drawing all work upon the same principle: the starting stock is drawn through a die to reduce its diameter and increase its length. Usually, the die is mounted on a draw bench. The starting end of the workpiece is narrowed or pointed to ...
This must be done because drawing wire hardens it, which causes the wire to become brittle. Brittle wire that has not been annealed may snap during the drawing process (or develop microscopic or macroscopic cracks, which may weaken the piece or "grow" with further working). With a mandrel, a draw plate can be used to draw tubes of metal. Plates ...
A list, usually tabular and often on the drawing (if not accompanying the drawing on a separate sheet), listing the parts needed in an assembly, including subparts, standard parts, and hardware. There is no consistently enforced distinction between an L/M, a BoM, or a P/L. PLM: product lifecycle management; plant lifecycle management: See also ...
For <, spiral-ring pattern; =, regular spiral; >, loose spiral. R is the distance of spiral starting point (0, R) to the center. R is the distance of spiral starting point (0, R) to the center. The calculated x and y have to be rotated backward by ( − θ {\displaystyle -\theta } ) for plotting.

The classic reproduction methods involved blue and white appearances (whether white-on-blue or blue-on-white), which is why engineering drawings were long called, and even today are still often called, "blueprints" or "bluelines", even though those terms are anachronistic from a literal perspective, since most copies of engineering drawings ...
