Svg Namespace

In the SVG documents exported by FreeCAD's Drawing Module and used as page templates, several custom attributes can be used, originally for FreeCAD's own internal use, but could also be used by other FreeCAD-aware applications in the future. These attributes all use the freecad: namespace prefix. The namespace URL defined in those SVG documents refers to this page.

Usage
One pixel = one millimeter.

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:

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

Additional information for Working space and Title block may be added, and is defined on the Drawing templates page.

freecad:EditableText
To use any of the freecad: attributes in your SVG documents, you must first define the freecad namespace as an attribute of the opening tag:

Defines a text in a template that can be edited by FreeCAD.

Example:

freecad:basepoint1
Defines the first point of a Draft Dimension object (represented as a group in a SVG document). This attribute is used when importing the SVG fragment in FreeCAD, in order to recreate the dimension object. The group contains paths and other graphical items to correctly render the dimension object in other SVG applications.

Example:

freecad:basepoint2
Defines the second point of a Draft Dimension object (represented as a group in a SVG document). This attribute is used when importing the SVG fragment in FreeCAD, in order to recreate the dimension object. The group contains paths and other graphical items to correctly render the dimension object in other SVG applications.

Example: see freecad:basepoint1

freecad:dimpoint
Defines the point of a Draft Dimension object through which the dimension line passes. This attribute is used when importing the SVG fragment in FreeCAD, in order to recreate the dimension object. The group contains paths and other graphical items to correctly render the dimension object in other SVG applications.

Example: see freecad:basepoint1

Example of code freecad:EditableText
This example is taken from a cartridge to a sheet A3_Landscape

Explanations
Beginning of the framework

Data on the framework

Beginning of the text block

All the information about the text that will be displayed

Coordinates and identity where the text will appear

Here AuthorName is the var managed by freecad:editable who saves the string to change that will be displayed

Coordinates and identity of the text that is displayed by default and   means the end of the block text

Other blocks texts and end  the framework grouping text blocks

It is possible after having worked the Inkscape SVG file as the file no longer works, it is possible that information has gone missing.

Then check that the edit text is not modified

Example :
 * editable = "AuthorName"
 * replace by freecad:editable = "AuthorName"
