Table 1. Main formats
A0 is taken as the initial format, and the rest are created by dividing it into two equal parts parallel to the smaller side of the previous format (Fig. 1).
Frame Each picture has a frame that delimits its area. The frame is drawn with basic thick connecting lines: these lines are drawn at a distance of 5 mm from the edge of the sheet on three sides of the sheet and 20 mm on the left side of the sheet; A margin (20 mm) is left to fill the pattern in the kit (Fig. 15).
Main entrance. The main text is placed in the lower right corner of the figure; it contains information about the image of the part in the drawing (Fig. 15)
By default, the parent entry is placed along the long or short side of the list; An exception to this rule is the A4 format, in which the main text is placed on the short side of the sheet (see Figure 16). To save paper in training drawings, A4 body text can be placed along the long side of the format. Figure 16 shows the development drawing master record form and an example of filling it out.
a) The name of the subject;
b) what materials the part is made of;
c) The mass of the object (expressed in kilograms);
d) Drawing scale;
e) Date of approval of the drawing;
These data are shown on the graph under the numbers 1, 3, 5, 6, 10-13. Column 2 indicates the symbol (number) of the drawing. This symbol itself is written in the upper left corner of the figure, rotated 180 degrees. This makes it easier to find drawings that are stored unfolded without having to look at the album. Figure letter to chart 4 posted. Unit production drawings are designated with the letter I, assembly series drawings with the letter A, serial or repeated production drawings with the letter B.
T
he serial number of the list is written in the 7th column. If the drawing consists of one sheet, column 7 is not filled in. The total number of documents is indicated in column 8. In column 9, the name or distinctive index of the company that issued the drawing is affixed. Columns 14-18 are calculated as a table of changes.
An enterprise that preserves its original may make changes (additions) to the drawing in compliance with the provisions of GOST 2.503-74. In this case, the letter of the change (a, b, c and other letters) is placed in column 14 and repeated next to the change made. Columns 15-18 are also filled in. Note that if the changes are not framed in this way, then the drawing cannot be used.
Conclusion. Today we always feel the need for drawings. Because we could visualize the drawing and see what it looks like through the drawings. After drawing a part or object, it is always necessary to draw a graph of the drawing. Because through the drawing schedule, you can get full or partial information about the part.
