Centreline creation (areal to linear)

I have a set of OS MasterMap shapefile vectors, where the roads, rivers, railways, etc are represented as multiple areal/polygon sections.

I'm using GM (11.02) to pre-process the raw data for a 3rd party simulation terrain generation tool.

That other tool really wants the roads etc presented as simple linear (polyline) features, so I'm wondering if there's a way to generate a centreline vector from each areal segment?

I have tried the 'Area to line' converter, but that seems to use the outside edge of the areal, rather than the centreline.

    There is not a tool in Global Mapper to generate a center-line representation of an area feature.
