+The specification of →[[en:infra-convert:user:terms#Characteristic (test-, quality-)|characteristics]] in the technical drawings follows defined rules. Such rules are laid down in international and national norms, but also company publications (factory standards). Misunderstandings are avoided between the customer and the supplier when reference is made to rules of interpretation, despite a reduction in the documentation effort required. A **class** refers to a rule and thus specifies the context in which the characteristic properties are to be understood.
 The classes listed at this point, sorted into the following groups, can be assigned in #@IC_HTML@#. The classes relate to recognised standards (see “References” column). Unless otherwise stated, the unit of measurement always applies to tolerance limits as well.

 Vector graphic formats, on the other hand, store graphic elements as unique, mathematically described graphic primitives. The latter mean basic geometric elements such as straight lines, arcs, and splines, as well as surfaces such as circles, polygons, and spline surfaces. Texts are stored either as polylines or with the help of character encoding (see also →[[en:infra-convert:user:terms#font|Font]]).

-In addition to the purely visual representation of characters, the unambiguous definition of characters is important for the automatic analysis of technical drawings. PDF files are generally used to displaying characters correctly. This is because the character definitions used are saved in the file. This is (unfortunately) different with the CAD exchange formats DXF, DWG and IGES. In them only the references to characters are stored in font files.

Supplying these fonts would disproportionately increase the cost of #@IC_HTML@# licenses. For this reason, #@IC_HTML@# replaces fonts not installed on the computer with visually similar fonts when loading drawing files. If this is the case, a note message is issued.

 Even if it is technically possible, a project should always only refer to an object that is subject to a test and, if necessary, follow-up tests. This may be, for example, the initial sampling of a product and its subsequent re-sampling (first-piece approvals, requalifications).

+==== Simplified indications ====
+By using a **simplified specification**, requirements for a geometry element are specified in simplified form and explained elsewhere in the drawing, for example next to a view or near the title block. This type of specification can be useful if there is not enough space available in a view or if a specification applies to several separate geometry elements and is specified more than once.
+The following example shows the principle for surface specifications and geometric tolerance specifications.
