Single step file example not working

[Chris-A13]

Hello,

I don't know if this forum is active but I have installed the AOC-XCHANGE and then I tried running the example code but it keeps coming up with the error 'from OCC.Core.Geom import Geom_Curve, Handle_Geom_Plane'
Do I need to do anything to the example code to make it work?

Any help with this would be greatly appreciated,
Regards,
Chris
