SVG templates creation
Vytváření šablon pro modul Výkresy je velmi snadné. Koukněte na výukový program Výkres Šablona Jak. Šablony jsou SVG soubory, které jsou vytvořené nějakou aplikací schopnou vyexportovat SVG soubory, jako je třeba Inkscape. Musí být dodrženy pouze násleující 2 pravidla: width="1067mm" height="762mm" or width="1067" height = "762" Although svg supports inches ("42 in"), these are currently not supported by FreeCAD, so it's always better to have your svg page size specified in millimeters. The "viewBox" attribute must have the same value, for example: viewBox="0 0 1067 762" This text above (which is actually an XML comment) must be on a separate line, and not embedded in the middle of other pieces of text. Beware that if you reopen and resave your template in inkscape, after adding the above line, inkscape will keep the line, but will add other xml elements on the same line, causing the template to not work anymore. You will need to edit it with a text editor and isolate the comment above on its own line again.
 * Jeden pixel = jeden millimeter
 * Ve vytvořeném SVG kódu musíte do místa kde chcete aby se zobrazoval Váš výkres (například na konec souboru před značku ) vložit následující řádek:
 * You must insert, somewhere inside your svg code, where you want the contents of the drawing to appear (for example at the end of the file, just before the last tag), the following line:

Namespace
xmlns:freecad="http://www.freecadweb.org/wiki/index.php?title=Svg_Namespace" Navíc k těmto dvěma pravidlům mohou být pro verze FreeCADu 0.14, revize 2995 do šablony přidány ještě informace o Pracovním prostoru a Popisovém poli pro nástroj ortografického zobrazení. tyto informace definují kam může a nemůže FreeCAD umístit zobrazení.
 * Several objects (specifically those created with the Drawing_Draft command and if your template has editable texts) use a special Svg Namespace specific to FreeCAD. This makes FreeCAD able to detect specific items inside svg files, that other applications will just ignore. If you plan to use any of these, you must add this line inside the opening tag, for example together with the other xmlns lines added by inkscape:

To define the Border, the following line must appear before the tag in the svg file. Where X1, Y1, X2, Y2 are defined as:
 * X1 is the X axis distance from the left edge of the page to the left side of the Border.
 * Y1 is the Y axis distance from the top edge of the page to the top of the Border.
 * X2 is the X axis distance from the left edge of the page to the right side of the Border.
 * Y2 is the Y axis distance from the top edge of the page to the bottom of the Border.

To define the Title block the following line must be inserted before the tag and after the Working space tag. Where X1a, Y1a, X2a, Y2a are defined as:
 * X1a is the X axis distance from the left edge of the page to the left side of the Title block
 * Y1a is the Y axis distance from the top edge of the page to the top of the Title block
 * X2a is the X Axis distance from the left edge of the page to the right side of the Title block
 * Y2a is the Y axis distance from the top edge of the page to the bottom of the Title block
 * X1a <= X1 or X2a >= X2
 * Y1a <= Y1 or Y2a >= Y2

The following is an example of the code that defines the Working space and Title block areas that are to be inserted before the tag. You needn't specify a title block, but if you do it must be defined on the next line immediately following the Working space:

In order to enable up to scale printing, the real word size has to be given in the width and height attributes of the SVG-Tag. The size of the document in user units, (px), has to be given in the viewBox attribute.

The following is to be formatted like the example below where:
 * xxx = pixel width
 * yyy = pixel height


 * V šabloně může být umístěno několik uživatelských atributů. Seznam aktuálně dostupných atributů je na stránce Svg Namespace.

DXF templates
Since version 0.15, FreeCAD can reliably export a Drawing page to the DXF format. This system also uses templates. If a dxf file with the same name is found in the same folder as the SVG template used for a page, it will be used for export. If not, a default empty template is created on the fly.

Consequently, if you create your own SVG templates, and wish to be able to export the Drawing pages that you create with it to DXF, you just need to create a corresponding DXF template, and save it with the same name in the same folder.

DXF templates can be created with any application that produces DXF files, such as LibreCAD. You then need to edit them with a text editor, and add two additional lines, one at the beginning or end of the BLOCKS section, and another at the beginning or end of the ENTITIES section, which are where FreeCAD will add its own blocks and entities.

A very simple template looks like this:

999 FreeCAD DXF exporter v0.15 0 SECTION 2 HEADER 9 $ACADVER 1 AC1009 0 ENDSEC 0 SECTION 2 BLOCKS $blocks 0 ENDSEC 0 SECTION 2 ENTITIES $entities 0 ENDSEC 0 EOF

The above template doesn't contain any entity. If you create your DXF file with a CAD application, there will likely be much more content inside the HEADER, BLOCKS and ENTITIES sections.

The two lines that FreeCAD will be looking for are "$blocks" and "$entities". They must exist in the template, and they must be placed on their own line. You can choose to place them right after the BLOCKS or ENTITIES line, which is easier (just use the "search" function of your text editor to find them), or at the end, just before the "0 ENDSEC" lines (beware that there is one for each SECTION, make sure to use the ones relative to BLOCKS and ENTITIES). The latter method will place the FreeCAD objects after the objects defined in the template, which might be more logical.
