+## Additional features inside SVG files
+
+### SVG can define additional features:
+
+* Movement Range: shapes inside the SVG with fill and stroke color Red (#FF0000
+  (RGB: 255, 0, 0)) and with fill and stroke opacity 0, allow software to
+  identify these shapes as a movement range of the device.
+
+* Connection Input (Pigtail): shapes inside the SVG with fill and stroke color
+  Green (#00FF00 (RGB: 0, 255, 0)) and with fill and stroke opacity 0, allow
+  software to identify these shapes as a connection input (pigtail) part of the
+  device.
+
+SVG needs to be aligned with the GDTF 3D model. GDTF 3D front is down in SVG.
+
+> Note: the opacity 0 is used for backwards compatibility
+
+> Example: If Pigtail is at the back of the unit, is drawn up in SVG.

+Attached examples:

+
+> **Note**
+> The top SVG contains this element generating the pigtail. As the opacity is set the zero, in the rendered SVG you will not see it.
