====== Automatic stamping ======
----
A characteristic or several characteristics can be automatically →[[en:infra-convert:user:terms#Stamp/stamps|stamped]] with this function. It is necessary that the drawing file is available in the drawing format DWG, DXF or IGES or in PDF format, see →[[en:infra-convert:user:terms#Drawing data format|Drawing data format]].
**The stamp-with-dialogue**
The stamp-with dialog allows you to specify basic characteristic properties when stamping. It is displayed at the bottom left of the drawing window when the **Stamp tool** is activated. In addition to the stamp number with prefix and suffix (1), these are the category and tag (2) as well as the general tolerance tables to be used (4). The set of selected tolerance tables can be added to a quick selection (4). Use the **Reset** button ({{:en:infra-convert:user:interface:icon_zuruecksetzen.png?nolink&15|}}) to restore the default values.

**Note** The preselection of tolerance table and stamp number via the Stamp with dialog is available from program version 4.4.0.
\\
**Categories**
If you leave the category preselection on **Automatic**, the drawing entries are automatically evaluated according to which →[[en:infra-convert:user:terms#category_characteristic|categorie]] they are. The following are assigned accordingly: 1) Standard feature, 2) Control dimension (laterally rounded frame), 3) Theoretically exact dimension (rectangular frame), 4) Auxiliary dimension (round brackets) and 5) Raw dimension (square brackets). The prerequisites for the recognition of the frames are that they consist of straight lines (and semicircles).\\ {{ :en:infra-convert:user:functions:kategorieerkennung.png?nolink |}}

**Spezialfälle**
In some cases, a special procedure is necessary. The most important cases are described below.
|< 100% 20% 50% 30%>|
| The drawing entry is not grouped | The elements of a drawing entry are available individually and are recorded individually when stamping. This case mainly affects PDFs. Use the **Stamp as group** function here.\\ **See** Functions > Characteristics > [[en:infra-convert:user:functions:ballooning_group|Stamp Automatically (Grouped)]] | {{ :en:infra-convert:user:functions:zeichnungseintrag_zerlegt_beispiel.png?nolink |}} |
| The drawing entry is not fully character-coded | Text characters, usually graphic symbols, are not character-coded but consist of geometric elements. The **Stamp with preset** function is available for this case.\\ **See** Functions > Characteristics > [[en:infra-convert:user:functions:ballooning_preset|Stamp with preset]] | {{ :en:infra-convert:user:functions:zeichnungseintrag_unvollstaendig_beispiel.png?nolink |}} |
| The drawing entry has a specific context | A drawing entry can only be interpreted correctly in the context of the drawing. One example is the coordinate dimensioning. The **Stamp with default** function is available for this case.\\ **See** Functions > Characteristics > [[en:infra-convert:user:functions:ballooning_preset|Stamp with preset]] | {{ :en:infra-convert:user:functions:zeichnungseintrag_im_kontext_beispiel.png?nolink |}} |
