The vertices are in the graphics object.
Just use [[ ]] to get them out.

ListPointPlot3D[vertices ,BoxRatios->Automatic]

Hope this helps,

I am sure I have done this before but I can't for the life of me
remember how, and I can't find it in the manual. Some help would be much
appreciated. I'd like to find the coordinates of the vertices of a
truncated cube.

Whilst Vertices[cube] correctly gives me the coordinates of a cube
Vertices[Truncate[Polyhedron[Cube]]] doesn't do what I want because
Truncate[Polyhedron[... is a graphics object not a polyhedron object. So
can I convert the graphics object into a polyhedron and use vertices, or
work out the vertices some other way (for a cube this is trivial to do
but for more complicated shapes this is much more tedious)
