+Nomenclature
+
+A new nomenclature tool appears in the menu: project -> Add a nomenclature.
+The nomenclature is presented in the form of a configurable table separated into two parts: the display (the form) and the content (the background).  
+- Display: the size and position of the table, the margins between text and the table cell, the alignment of the text in the cells and the font. The configuration of the table headers and the table itself are separate.  
+- Content: the information to display in the table and the order in which it should be displayed.  
+
+![](https://download.tuxfamily.org/qet/images_depeche_linuxfr/08/dialogue_nomenclature.png "nomenclature dialogue")
+
+In order to speed up the establishment of a nomenclature, it is possible to export / import the display and content configurations separately. This is the "Configuration" part that can be seen in the photos above.  
+
+Behind the scenes, an SQLite database does the work, so setting up the content is nothing more or less than an SQL query created using a dialog (screenshot by right).  
+The SQL query is configured as follows (from top to bottom in the screenshot):  
+- “Available information”: the information to display;  
+- "Filter": filter the information (is not empty, is empty, contains, does not contain, is equal to, is not equal to) only one filter can be applied per information, it is not possible combine several;  
+- "Type of elements": allows you to filter on what type of element you want to obtain information.  
+
+At the bottom, a checkmark "SQL query" allows you to edit a personalized query, if the basic options are not sufficient.  
+
+When a nomenclature is too large to be contained in a single folio, it is possible to separate it on several folios, the tables of each folio are then linked together. When creating a nomenclature, this option is activated by default, which has the effect of adding the necessary number of folios, adding a table in each of them and linking them together.  
+
+Finally two buttons are available in the property panel:    
+- "Fit the table to the folio": positions and adjusts the size and determines the number of rows in the table in relation to the folio;  
+- "Apply geometry to all tables linked to this one": applies the three properties mentioned above to all linked tables in order to save time and maintain aesthetic consistency.  
+
+And to finish a table ![](https://download.tuxfamily.org/qet/images_depeche_linuxfr/08/tableau.png" "table")
+
+
+Summary
+
+The old summary has been completely removed from the code in order to make room for the new one which is exactly the same as the nomenclature (a large amount of the code is common), with the exception of the SQL query (and its dialog to configure it) which offers specific information for editing a summary.  
+
+Export of the internal database  
+
+The database used by the nomenclature and the summary can be exported in a “.sqlite” file.  
+Currently this is irrelevant, as the function was created during development for debugging purposes, we left it.  
+Note that the database will become increasingly important in the future of Qet.  
+
+
+Export of the wiring list  
+
+In order to be able to use the wiring number printers more easily, the names of conductors can be exported in CSV format, the export respects the quantity of conductors in order to print the right quantity of numbers, for example a potential numbered 240 composed of 3 wires will give 6 × 240 (2 numbers per wire × 3 wires) in the CSV.
