A T-square is a technical drawing instrument used by draftsmen primarily as a guide for drawing horizontal lines on a drafting table. The instrument is named after its resemblance to the letter T, with a long shaft called the "blade" and a short shaft called the "stock" or "head".
T-Square is a small part of the reason people use today's computers for drafting, architecture, drawing and illustration and engineering. Prior to this revolution and in some places to this day, draftsmen and women used triangles , wood or metal T-squares , pencils and technical pens on film and paper .
"Parallel lines" can be drawn by moving the T-square and running a pencil or technical pen along the T-square's edge. The T-square is used to hold other devices such as set squares or triangles. In this case, the drafter places one or more triangles of known angles on the T-square — which is itself at right angles to the edge of the table ...
A T-square is a style of square where the blade is fixed onto on into the middle of the stock, forming a 'T' shape. The most common type of T-square is a guide for drawing horizontal lines on a drawing board, and can guide a set square to draw vertical or diagonal lines. [27] Other types of T-square are used by woodworkers and glaziers for ...
An alternative to the T-square is the parallel bar which is permanently attached to the drawing board. It has a set of cables and pulleys to allow it to be positioned anywhere on the drawing surface while still remaining parallel to the bottom of the board. The drafting machine replaces the T-square and triangles.
The issuance of a drawing from the engineering/design activity to the production activity. In other words, the event when a draft becomes a completed, official document. A stamp on the drawing saying "ISSUED" documents that RTP has occurred. RTV: room-temperature vulcanizing; return to vendor: 1. RTV sealants, a way to seal joints. 2.
In the 20th century, technical drawing underwent yet another transformation with the introduction of drafting tools such as the T-square, compasses, and protractors. These tools helped drafters achieve the high degree of precision necessary for increasingly complex projects, such as skyscrapers, airplanes, and automobiles.
