Coordinate System Touchoff
--------------------------

To touch-off an axis, use a QPushButton and QLineEdit to set the touch-off value.
Optionally you can have a QComboBox to select the Coordinate System to touch off
to.

	Touch Off Axis, QPushButton, touchoff_pb_(axis letter)
	Touch Off Value, QLineEdit, touchoff_le
	Coordinate System, QComboBox, touchoff_system_cb

Optionally you can have a QLineEdit for any axis by adding a string type Dynamic
Property named `source` to the QPushButton and the value contains the object
name of the QLineEdit that you want to use. See :doc:`property`
