In casting, a pattern is a replica of the object to be cast, used to form the sand mould cavity into which molten metal is poured during the casting process. Once the pattern has been used to form the sand mould cavity, the pattern is then removed, molten metal is then poured into the sand mould cavity to produce the casting.

The Iron Foundry, Burmeister & Wain, by Peder Severin Krøyer, 1885 A Foundryman, pictured by Daniel A. Wehrschmidt in 1899 A foundry is a factory that produces metal castings . Metals are cast into shapes by melting them into a liquid, pouring the metal into a mold, and removing the mold material after the metal has solidified as it cools.
A pattern book, or architectural pattern book, is a book of architectural designs, usually providing enough for non-architects to build structures that are copies or significant derivatives of major architect-designed works. A number of pattern books have been very influential in spreading architectural styles.
Lost-foam casting (LFC) is a type of evaporative-pattern casting process that is similar to investment casting except foam is used for the pattern instead of wax. This process takes advantage of the low boiling point of polymer foams to simplify the investment casting process by removing the need to melt the wax out of the mold.
The designers use the PDK to design, simulate, draw and verify the design before handing the design back to the foundry to produce chips. The data in the PDK is specific to the foundry's process variation and is chosen early in the design process, influenced by the market requirements for the chip.
Valentina is an open source pattern drafting software tool, designed to be the foundation of a new stack of open source tools to remake the garment industry. [5] The program was named after mother of the founder Roman Telezhinsky, a cutter by profession, who gave him the idea for the project.
Pattern shifting: Pattern shifting involves increasing the overall dimensions of a pattern by moving it around at a constant distance. After the pattern is moved, the outline is redrawn in order to produce the same results as cut-and-spread. Computer grading: Computer grading is the most recent development in grading technology.
