Foreword
ISO (the International Organization for Standardization) is a worldwide
federation of national standards bodies (ISO member bodies). The work of
preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which
a technical committee has been established has the right to be represented
on that committee. International organizations, governmental and non-
governmental, in liaison with ISO, also take part in the work. ISO
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard ISO 3098-5 was prepared by Technical Committee
ISO/TC 10, Technical drawings, product definition and related
documentation, Subcommittee SC 1, Basic conventions.
ISO 3098 consists of the following parts, under the general title Technical
product documentation — Lettering:
— Part 0: General requirements
— Part 1: Currently used characters
— Part 2: Greek characters
— Part 3: Diacritical and particular marks for the Latin alphabet
— Part 4: Cyrillic characters
— Part 5: CAD lettering of the Latin alphabet, numerals and marks

Part 5:
CAD lettering of the Latin alphabet, numerals and marks
1  Scope
This part of ISO 3098 specifies the general requirements for computer-aided design and draughting (CADD)
lettering, in accordance with all other parts of this International Standard, to be used in technical product
documentation (in particular on technical drawings).
It includes basic conventions as well as rules for the application of CAD lettering using the techniques of numerically
controlled lettering and draughting systems.
2  Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this part of
ISO 3098. At the time of publication, the editions indicated were valid. All standards are subject to revision, and
parties to agreements based on this part of ISO 3098 are encouraged to investigate the possibility of applying the
most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid
International Standards.
ISO 3098-0:1997, Technical product documentation — Lettering — Part 0: General requirements.
ISO/TR 10623:1991, Technical product documentation — Requirements for computer-aided design and
draughting — Vocabulary.
3  Definitions
For the purposes of this part of ISO 3098, the definitions given in ISO 3098-0 apply. Further definitions used in
computer-aided design and draughting are given in ISO/TR 10623.
3.1  proportional spacing arrangement: Arrangement of graphic characters in the direction of writing spaced
according to their natural width.
3.2  tabular spacing arrangement: Arrangement of graphic characters in the direction of writing within a
constant-width space at predetermined positions, independent of the natural width of the characters.

4  General requirements
The general requirements for CAD lettering are specified in ISO 3098-0.
5  Requirements for CAD lettering
5.1  The types of CAD lettering are as follows:
— lettering type CB, vertical (V): see figure 1 (preferred application);
— lettering type CB, sloped (S);
— lettering type CA, vertical (V): see figure 2;
— lettering type CA, sloped (S).
The dimensions of these types of CAD lettering are specified in table 1.
NOTE —  In contrast with type CB, the character width (in the direction of lettering) and the line width of lettering type CA
may be reduced by a factor of 2 (to give approximately lettering type A in accordance with ISO 3098-0).

ISO ISO 3098-5:1997(E)
5.2  The types of spacing arrangements are as follows:
— tabular spacing (T): see figure 3;
— proportional spacing (P): see figure 4.
5.3  Each member of a graphic character set is established within a character box. The elements of the characters
shall be positioned by means of a grid system. The following criteria for any member of a graphic character set shall
be met:
a) dimensions (see figures 5 and 6), shape and location;
b) type of spacing arrangement (see figures 3 and 4);
c) points of adjustment within the character box (see figure 7).

6  Alignment
Each character, each line of text and each area to be filled by several lines of text shall have one point of alignment.
The indication and location of points of alignment are given in table 2 and figures 7 and 8.
If numerical values are written in decimal form, the alignment shall be made with respect to the decimal sign
1)
(comma ). An example is shown in figure 9.

7  Designation
A graphic character set of a CAD lettering type shall be designated in accordance with ISO 3098-0.
EXAMPLE — A graphic character set of lettering type CB in proportional spacing arrangement, vertical, Latin alphabet, size
3,5 mm, shall be designated as follows:
Lettering ISO 3098 - CB PVL - 3,5
8  Form of characters
The characters of the lettering type CB shown in tables 3 to 6 are presented within an imaginary grid which is
necessary for identification of positioning and proportions.
An example, shown in figure 12, presents a certain character within an imaginary grid.
Figure 12
