1. TERMS AND DEFINITIONS

1.1. The font size h is a value determined by the height of the capital letters in millimeters.

1.2. The height of capital letters h is measured perpendicular to the base of the line.

The height of lowercase letters c is determined from the ratio of their height (without processes k) to font size h, for example, c=7/10h (Fig. 1 and 2).

1.3. The width of the letter g is the largest width of the letter, measured in accordance with the drawing. 1 and 2 is defined in relation to the font size h, eg g=6/10h, or in relation to the font line thickness d, eg g=6d.

1.4. Font line thickness d - thickness, determined depending on the type and height of the font.

1.5. Auxiliary grid - a grid formed by auxiliary lines into which letters fit. The pitch of the auxiliary grid lines is determined depending on the thickness of the font lines d (Fig. 3).

Table 3

All inscriptions on the drawings (in the main inscription, dimensions, technical requirements and conditions, etc.) are made in drawing font in accordance with GOST 2.304-81.

The size standard drawing font is defined height h capital (capital) letters in millimeters. The standard specifies the following font sizes: 2.5; 3.5; 5; 7; ten; fourteen; 20. For example, the height of the capital letters of font size 14 is 14 mm, size 5 is 5 mm, respectively, and so on. (Fig. 20).

Font line thickness d- thickness, determined depending on the type and size of the font (Fig. 20).

Letter widthg- the maximum width of the letter, determined in relation to the font size h, For example, g=6/10 h, or in relation to the line thickness of the font d, For example, g=6 d.

Fig.20. Basic font parameters: a) direct font; b) italic font.

The standard establishes four types of font: a) type BUT no slope ( d=1/14 h); b) type BUT with a slope of about 75 0 ( d=1/14 h); c) type B no slope ( d=1/10 h); d) type B with a slope of about 75 0 ( d=1/10 h). The difference between font types is not in the design of letters and numbers, but only in size. d- the thickness of the font lines. Type A and type B font parameters are shown in Tables 3 and 4.

Table 4. Type B font options

Auxiliary grid- a grid formed by auxiliary lines into which letters fit. The step of the auxiliary grid lines is determined depending on the thickness of the font lines d(fig.21).

Examples of the typeface of the Russian alphabet type A are shown in Fig. 22, 23; font sizes are given in table 5. An example of the style of Arabic and Roman numerals is shown in fig.24.

Notes:

1. Distance a between letters whose adjacent lines are not parallel to each other (for example, GA, AT), can be reduced by half, i.e. for thickness d font lines.

2. The vertical branches of the letters D, C and U go at the expense of the spaces between the lines; the lateral processes of the letters Ts and Shch go due to the gap between the letters.

3. The minimum distance between words separated by a punctuation mark is the distance between the punctuation mark and the word following it.

4. A font without an inclination is used relatively rarely, mainly for names, headings, designations in the main inscription, in the margin of the drawing, etc.

1.2. Basic requirements for the design of graphic works

All graphic assignments must be completed on standard sheets drawing paper (A3 or A4) and have a frame of the drawing field and the main inscription in the form No. 1 GOST 2.104-68 (except for the task "Title page"). The frame of the drawing field is made by a solid main line with a thickness S at a distance from the outer borders of the sheet: on the right, below and above - 5 mm, on the left - 20 mm. The main inscription is always located in the lower right corner of the sheet. A field of 20 mm on the left side is intended for filing and stitching drawings. The main inscription is made with solid main and thin lines. The dimensions, location and content of the main inscription are shown in Figure 25.

Figure 25. Dimensions of the title block table according to form 1.

In the columns of the main inscription and in additional columns indicate:

- in column 1 - the name of the product in accordance with GOST 2.109-73;

- column 2 - document designation in accordance with GOST 2.101-80 .;

– in column 3 – symbol material (this column is filled only on the drawings of parts);

- in column 4 - the letter assigned to this document in accordance with GOST 2.103-68 (the column is filled in sequentially, starting from the leftmost cell. For training drawings, we use the letter "U");

- in column 5 - the mass of the product in kilograms according to GOST 2.109-73;

- in column 6 - scale (put down in accordance with GOST 2.302-68);

- in column 7 - the serial number of the sheet of the document, if the drawing is made on several sheets. On documents consisting of one sheet, the column is not filled out;

- in column 8 - the total number of sheets of the document. The column is filled out only on the first sheet;

- in column 9 - the name, distinctive index or code of the enterprise that issued the document, for tasks in engineering graphics - VTUZ, gr. XXXX;

- in columns 10 - the nature of the work performed by the person signing the document;

- in columns 11 - the names and initials of the persons signing the document:

- in columns 12 - signatures of persons whose names are indicated in columns 11;

- in column 13 - the date of signing the document;

- in columns 14–18 - the columns of the table of changes made to the document in accordance with GOST 2.503-68 are not filled in on the training drawings;

- in column 19 - document designation (see column 2), rotated by 180 0 for A4 format and for formats larger than A4 when the main inscription is located along the long side of the sheet and by 90 0 for formats larger than A4 when the main inscription is located along the short side of the sheet .
