Introduction date 01.01.82

This International Standard specifies drawing fonts for use on drawings and other technical papers all branches of industry and construction.

1. TERMS AND DEFINITIONS

1.1. Font size h - value determined by the height of capital letters in millimeters.1.2. The height of capital letters h is measured perpendicular to the base of the line. Height lowercase letters c is determined from the ratio of their height (without processes k) to font size h, for example, c = 7/10 h (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 determined in relation to the font size h, for example, g = 6/10 h, or in relation to the thickness of the font line d, for example, g = 6 d.1.4. The thickness of the font line d is the 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).

2. TYPES AND SIZES OF FONT

2.1. The following types of font are installed: type A without inclination (d = 1/14 h) with the parameters given in Table. 1; type A with an inclination of about 75° (d = 1/14 h) with the parameters given in Table. 1; type B without slope (d = 1/10 h) with the parameters given in Table. 2; type B with an inclination of about 75° (d = 1/10 h) with the parameters given in Table. 2.

The minimum distance between words e separated by a punctuation mark is the distance between the punctuation mark and the word following it. When executing documents in an automated way, it is allowed to use fonts used by computer technology. In this case, their storage and transfer to users of documents should be ensured.

8. RULES FOR WRITING FRACTIONS, INDICATORS, INDICES AND MAXIMUM DEVIATIONS

8.1. Fractions, indicators, indices and limit deviations are performed in accordance with Table. 4 font size:

one step smaller than the font size of the main value to which they are assigned;

the same size as the font size of the main size.

A font is a uniform outline of all letters of the alphabet and numbers, which gives them a common characteristic appearance. drawing font should be easy to read and easy to write. On the drawings and other design documents of all industries and construction, a drawing font is used, which establishes GOST 2.304-81 (ST SEV 851 - 78-ST SEV 855-78). GOST sets the following font sizes: (1.8); 2.5; 3.5; 5; 7; ten; fourteen; 20; 28; 40. The use of font size 1.8 is not recommended and is only allowed for font type B.
The font size is determined by the height of the capital letters in millimeters. The height of the h letters is measured perpendicular to the base of the line.
GOST established the following font types: type A with an inclination of about 75°; type A without slope. AT educational institutions usually use type B type with an inclination of 75 °.

To study the construction of letters and numbers and acquire the skills of writing them, several inscriptions should be made using an auxiliary grid. The grid consists of thin horizontal and oblique lines drawn at an angle of 75° to the horizontal line and is drawn with a 2T pencil. The distance between the parallel lines of the grid is equal to the thickness of the lines of the font selected for writing (Fig. 40). The thickness of the font lines d (Fig. 41) is determined depending on the type and height of the font h (font size).

The sizes of such parameters as the distance between letters in words a, the width of letters and numbers g, minimum distance between words e, the distance between the bases of the lines b (Fig. 41), for the most used font sizes of type B should be taken from Table. 5.
If the sentence contains punctuation marks, then the distance between words is determined by the distance from the punctuation mark to the first letter of the next word (Fig. 41).

If the inscription begins with an uppercase letter, and the rest of the letters are lowercase, then the height of the lowercase letters, except for the letters b, c, e, p, y, f, is equal to the previous font size (Fig. 41). For example, if the inscription is made in font size 10, then the height of lowercase letters is 7 mm. The height of lowercase letters b, c, d, p, y, f is equal to the height of uppercase letters of the font size used for the inscription.

The thickness of the stroke of uppercase and lowercase letters in the same word must be the same according to the accepted font size. If the inscription is made only in capital letters, then the first letter is not highlighted in height; all letters are the same height.

The constructions of numbers and letters of the Russian alphabet for type B font are shown in fig. 42. For clarity, the rectilinear sections are shaded, and the fillets and sloping elements are left light. The gaps between two adjacent letters that have non-parallel boundary lines visually appear to be enlarged, therefore, in combinations of letters L, GL, AD, AL, KA, HC, the gap between letters is halved, and in combinations GA and TA they are not done at all. Compare two spellings of the same word (Fig. 43). The first word is made with the same spaces between all letters (Fig. 43, a). In the second word (Fig. 43, b), the gap between the letters K and A is reduced by half, and between the letters G and A it is completely absent.

All inscriptions on the drawings are made by hand. When studying the construction of letters and numbers, it is necessary to use the auxiliary grid shown in Fig. 40, having mastered the skills of writing a font, you should use a simplified auxiliary grid (Fig. 44), which limits the height and width of letters, the spaces between letters and words. It is better to plot the dimensions of the elements of letters and numbers using a home-made marking ruler made of paper, since due to the thickness of a regular ruler, the dimensions are transferred inaccurately.

This line is made as follows. A strip of paper is taken and superimposed on the ruler from the division side. Then, with a sharpened pencil on a strip, mark the width of the letters and the spaces between them with strokes and set the size (Fig. 45). These marking lines are made for different sizes font and put down the font size on each, so as not to confuse.

With sufficient skill in making inscriptions, a more simplified marking grid is used (Fig. 46), on which horizontal lines are drawn for sizes L; c and b and a few 75° slanted lines to keep the letters and numbers in line with the predetermined slant.

An example of writing letters and numbers using a simplified auxiliary grid is shown in fig. 47. Two thin lines are drawn at the distance of the font size, which limit the height of letters and numbers. Between them, in the middle, a third auxiliary line is drawn. On fig. 47, and letters are shown, the middle elements of which are located above the line, in fig. 47, b letters, the middle elements of which are under the middle line. Horizontal-
The main elements of the letter A and the number 4 are made using a line that is drawn at a distance "YES" from the base of the line (Fig. 47, b and e) i The spelling of some numbers is shown in Fig. 47, c. The number 3 has two spelling designs.

The designs of the letters of the Latin alphabet are shown in fig. 48, and Roman numerals - in fig. 49. GOST allows limiting Roman numerals to horizontal lines (Fig. 49, / and V).
On fig. 50 made the most commonly used signs. Their names are given in Table. 6.
