Scripting
TechDraw API and FreeCAD Scripting Basics.

The WeldingSymbol tool can be used in macros and from the Python console by using the following functions:

Svg Symbol Tiles

 * Individual symbols are formed by 64x64 pixel Svg files. Additional symbols can be created in an Svg program like Inkscape using one of the supplies symbols as a template.


 * Individual symbols are formed by 64x64 (nominal) pixel Svg files. The tiles actually have a "border" of 4px. The border ensures that the leader line and symbol meet nicely.
 * The symbol is drawn in black on a transparent background. The stroke is 0.5mm.
 * The leader passes below symbols for the arrow side and above symbols for the "other" side.
 * There is no particular naming standard other than to append "Up/Down" to the arrow/other side symbols where required.
