Name Space Clash
One thing to be aware of is as there is no management of global variable names by FreeCAD so there is the possibility of changing a variable from the system or another piece of code. Consequently it is a good idea to prefix your variables with something unique such as the routine name. For example to use a variablefrom a routine called 'alpha1' the global name could be 'FreeCAD.alpha1MyVariable'.
