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

The size of a standard drawing font is determined by the height h capital letters in millimeters. The standard sets the following font sizes: 2.5; 3.5; 5; 7; 10; 14; 20. Font 1.8 is allowed. For example, the height of capital letters in a font size 14 is 14 mm, size 5 is 5 mm, respectively, etc.

Font line thickness d– thickness, determined depending on the type and size of the font. The standard establishes four types of font: a) type A without tilt; b) type A with a slope of about 75 0; c) type B without tilt; d) type B with a slope of about 75 0.

The difference between font types is not in the design of letters and numbers, but only in size d – thickness of font lines.

Table 3

Type B font

Notes:

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

2. The vertical branches of the letters D, C and Ш come from the spaces between the lines; the lateral processes of the letters C and Ш are due to the space between the letters.

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

Non-slanted fonts are used relatively rarely, mainly for names, headings, designations in the main inscription, on the drawing margin, etc.

This work uses type 14 font B with a slope. Relationships between font sizes h and other sizes of letters and Arabic numerals are shown in Fig. 4 and in table. 3.

This standard establishes drawing fonts applied to drawings and other technical documents of all industries and construction.

1. TERMS AND DEFINITIONS

1.1. Font size h is a 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. The height of lowercase letters c is determined from the ratio of their height (without processes k) to the 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 line. 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. 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).

2. FONT TYPES AND SIZES

2.1. The following font types are installed: type A without slope (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 tilt (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.

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 must be ensured. (Changed edition, Amendment No. 2) 2.2. The following font sizes are set: (1.8); 2.5; 3.5; 5; 7; 10; 14; 20; 28; 40. Note.
