[CJAndrew84]

highlighted here from the code its a self reference as its RefDirection when it should be refDirection.

@jmirtsch this is causing issues in Validate.B

Thanks for reporting these. IfcOffsetCurve3D is a concept in IFC that I've not seen used, and expectation about support should be minimal. You have identified a couple of related bugs to this concept in the toolkit, I've revised this in the latest commit and nuget package. Let me know if you spot aspects that are still amiss.
