Coordinates of vertices

*To*: mathgroup at smc.vnet.net*Subject*: [mg87720] Coordinates of vertices*From*: "King, Peter R" <peter.king at imperial.ac.uk>*Date*: Wed, 16 Apr 2008 05:02:26 -0400 (EDT)*References*: <ftv8ro$7o1$1@smc.vnet.net> <200804141054.GAA13581@smc.vnet.net>

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) Thanks, Peter
