Rails for plotting: a classic of the genre or an indispensable subject
Each drawer is familiar with an object with which it is easy to draw parallel lines regardless of their angle of inclination or direction. This irreplaceable thing is called a flight, which creates additional conveniences while drawing by hand on a specialized wooden board.
The appearance of the tire and its distinctive features
The drawing rail is a kind of ruler, the shape of which resembles the letter T in its silhouette. As in the distant past, as in the present, this ruler is made mainly of high-quality plastic or wood, which meet all the requirements of draftsmen, the main among them are the ideality of the lines and the ability not to spoil the paper.
A rail made of wood is a long ruler with a perfectly flat surface, on the one hand it is cut into a short crossbar at a right angle, called the last head. The crosspiece consists of two small strips, which are fastened together with a neat screw. Plank, located in a stationary position, serves as a guide during the execution of the work of the draftsman.
What is the need for a ruler and basic requirements for it?
The flange is required preferably for horizontal lines and is much less common for inclined and vertical straight lines. For example, the inertial version of such rulers is made of transparent materials, in front of which there is a scale for conducting lines, side and back - a grid for measuring angles. That is, the Trough for drafting performs the function of the protractor, too.
The most ideal material for the manufacture of such rulers is a tree, ideal pear.
A more perfect version of the flight is a lever, which due to its convenience only speeds up the drawing process. Using it is very simple: you need to put the device on the board, pressing the head to the edge to the left. Move the vortex with the left hand, holding it by the head, with the other hand by the triangle.
In addition to these generally accepted varieties, advanced and modernized instruments are used, the details of which are made of glass and metal or wood.
Use and storage of a rail vehicle
Rails for drawing is one of the main pledges of the executed scheme and its quality. After all, the correctness, accuracy and quality of the drawing itself depends on the state of all the tools. Therefore, after completing the work, each time it is necessary to wipe the vortex and put it in the optimal place, inaccessible to moisture. Thanks to this care, wood and metal will have a pristine and perfect appearance.
When used correctly, the drawing square for drawing should be in a comfortable sliding position so that nothing can hinder its free movement.
