====== Stamp PDF ======

----

Drawings in PDF format have different qualities in terms of automatic readability (machine readability). Generally, PDF drawings do not reach the quality of CAD exchange formats (DXF, DWG, IGES). In this tutorial we describe how to quickly and safely create a test plan in #@IC_HTML@# depending on the structure of the PDF.

PDF drawings are exported from CAD systems with the main focus on visual requirements, i.e. human readability. However, the PDF export can be optimized for automated stamping in #@IC_HTML@#. Please note our recommendations for the configuration of the export. If you need advice, we will be pleased to support you.\\  **See** User manual > [[en:infra-convert:user#Export drawing from the CAD system]].

> **Note** Automatic stamping of PDF is possible only in the Pro version of #@IC_HTML@#.\\  **See** At a glance > [[en:infra-convert:info#The range and functions of basic and pro]|The range and functions of basic and pro]]

==== Step 1: Find out how a PDF is structured ====

**1) Is the content rasterized or vectorized?**

On the one hand, the drawing content can be described vectorially. The drawing elements are then made up of line segments, arcs, etc. This mathematical description ensures that even when zooming in, the content is still displayed razor-sharp. In raster graphics (also called: pixel graphics), on the other hand, image points (pixels) are stored in a raster. The further you zoom in, the more clearly they can be seen.

\\ 

**2) Does the PDF contain character-coded text?**

A computer can only interpret a text character as such if it is linked to a meaning by so-called character encoding (→[[en:infra-convert:user:terms#font|Font]]). You can check whether character encoding is applied using a PDF reader, for example Adobe Acrobat Reader. Activate the selection tool (**Selection tool for text and images** in Acrobat Reader) and try to select or highlight the text. If elements are highlighted, usually in blue color, coded text was detected. You can copy it (right-click > **Copy** or **Ctrl** + **C**) and paste it in a text editor, for example.

Four typical cases can be distinguished, as shown in the following examples: 1) no character-coded text is present; 2) texts, except graphic symbols, are character-coded; 3) as 2, but invisible, character-coded text overlays the visible, non-character-coded text; 4) all texts are character-coded.

==== Step 2: Stamp PDF depending on structure ====

In the following, depending on the structure, it is recommended how characteristics can be created from drawing entries.

== PDF without character coded text ==

Create the characteristics manually. To do this, double-click with the stamp tool at the position of the drawing entry and enter the relevant text in the quick entry dialog.\\  **See** Functions > Characteristics > [[en:infra-convert:user:functions:ballooning_man|Manually stamp]]

== PDF with partially character coded text ==

The **Stamp with preset** function has been specially developed for this use case (available from program version 3.3.0). Follow the instructions on this page:
\\  **See** Functions > Characteristics > [[de:infra-convert:user:functions:ballooning_preset|Stamp with preset]]

> **Recommended procedure up to program version 3.2.7:**\\ 
> Create characteristics one by one. The text fragments belonging to a characteristic can be evaluated automatically if you stamp them as a group (press **Ctrl** key, hold it down and draw a frame over the elements to be stamped or click the elements individually).\\  **See** Functions > Characteristics> Automatics stamping > [[https://wiki.elias-gmbh.de/doku.php?id=en:infra-convert:user:functions:ballooning#workflow|Workflow]] > Step 4c\\ 
> If a drawing entry contains a graphic symbol at the beginning of the text, for example the diameter sign in "⌀ 20", stamp the text as described previously. You then correct the property that was not interpreted or was interpreted incorrectly due to the missing character in the feature properties. For example, the class "Length" is recognized from "20". You then change this to "Diameter".\\ 
> Drawing entries with non-character-coded symbols in the middle of the dimension text, for example "20 ±0.1" with uncoded "±", as well as specifications that are complex in the description with characteristic properties, such as form and position tolerances, are best stamped directly manually.\\  **See** Functions > Characteristics > [[en:infra-convert:user:functions:ballooning_man|Manually stamp]]\\ 
> Example of a PDF with partially coded text:\\
