T-shaped ruler, also known as T-shaped ruler, is a "T" shaped ruler with a rung, which is composed of a ruler head and a ruler body that are perpendicular to each other, and is generally made of transparent plexiglass, and is often used with a drawing board when drawing drawings in engineering design. The T-shaped ruler is a tool for drawing horizontal lines and drawing with triangles, and can generally be directly used to draw parallel lines or as a support for triangles to draw straight lines at various angles with the ruler. The T-shaped ruler is mostly made of wood or plastic, and generally has three specifications: 600mm, 900mm and 1200mm.
How to use the T-ruler correctly] (1) The T-ruler should be placed on the left side of the drawing board, and it should be close to the edge, and it can be used by sliding up and down. (2) Lines can only be drawn on the side of the T-shaped ruler, and horizontal lines must be drawn from left to right. (3) When drawing the same drawing, the T-shaped ruler should not slide on the other sides of the drawing board, nor should it draw vertical lines.
4) Excessively long diagonal lines can be drawn with a T-shaped ruler. (5) Longer groups of straight parallel lines can also be plotted with a T-shaped ruler with an adjustable ruler. (6) The working edge should be kept straight, the scale is clear and accurate, and the ruler head and the ruler body are firmly connected, and the working edge cannot be used to cut the drawing.
7) The T-ruler should be hung when placed to ensure the straightness of the T-ruler.

The T-shaped ruler was an indispensable tool for drawing that was used a lot in the past, and it was shaped like the kanji "ding"."Named after it, the short horizontal and long vertical are 90 degrees in a mentoring relationship. Then the short horizontal can hook the edge of the drawing board and move it up and down, and the long vertical will always maintain the horizontal direction, and then with tools such as a triangular ruler, you can draw drawing drawing lines.
It's rare now, and the older generation of people do, and their ability to draw and read by hand is significantly stronger than that of the younger generation.

The T-shaped ruler is composed of a pirated reprimand, and the guide plate is perpendicular to the ruler plate and fixed. When used, the guide plate is only on the left side of the drawing board, and it can be moved up and down, and with the help of the ruler plate, you can draw a straight line in the horizontal direction.
-
Because both sides of the drawing board are not necessarily vertical, the lines drawn vertically and horizontally are not perpendicular to each other. Therefore, the T-ruler is generally used horizontally to use one side of the drawing board as a reference, and it is not recommended to use it vertically. If you're not a mechanical drawing, but a casual graffiti, there's no requirement, then it's okay to use it horizontally or vertically.

A T-ruler, also called a T-ruler, is used on hand-drawn paper. Mainly for the parallelism of the lines, not offset.

Answer: The T-shaped ruler is composed of two parts, the ruler head and the ruler body, and is generally made of transparent plexiglass.

The T-ruler is mainly used to draw horizontal lines and as a guide edge for a triangle. The T-shaped ruler is composed of two parts, the ruler head and the ruler body, and the material is plexiglass. T-rulers come in a variety of sizes and are generally used with drawing boards. There are two common T-rulers: fixed and movable.
When using, the ruler should be close to the left guide edge of the drawing board, hold the ruler with the left hand, push the ruler body with the right hand, and slide it up and down. When drawing a horizontal line, align the edge of the ruler with the position of the line to be drawn, the tip of the pen is close to the ruler, the barrel is slightly inclined to the right, and the line is drawn at a uniform speed from left to right.

Hello dear! Glad for your question! How long should the T-shaped ruler be designed in the room
There are three types of T-shaped rulers: 600 mm, 900 mm, and 1200 mm. I think that if you buy it yourself, you can buy a 600mm (also called No. 2 T-ruler), which is too big and inconvenient to use, and the desk in your dormitory is probably a single Xinjing desk, right? It is just right with a 600mm T-ruler.
In the future, it is all computer drawing, the use of T-ruler is less, with the manual drawing of No. 0 drawing, with a T-ruler of 1200mm, generally drawing No. 1 drawings below the use of 900mm or 600mm, commonly used 900mm T-ruler may be a little more.
Plastic defoamer, also known as plastic defoaming masterbatch, a part of plastic raw materials or recycled plastics often contain a trace amount of water, if not eliminated, will form bubbles or water lines on the surface of the processed products, which will affect the performance and appearance of the products. However, the traditional process of using electric drying machinery to eliminate moisture needs to dry raw materials in advance, resulting in inconvenient production, and there are shortcomings such as low production efficiency, power consumption, deterioration of processing environment, and increased production cost due to prolonging the processing time of products. The birth of plastic defoaming masterbatch (plastic defoamer) plays a pivotal role in the processing of plastic products containing moisture. >>>More
