exporting the geomatry from cst to matlab

hii..
i have made a simple waveguide structure with dielectric in it, now i want to export the geomatry to MATLAB how can i do that?
Thanks

U want to export the Geometry to matlab ? or its simulated data ? Which tool of the Matlab will support such 3D structure ?

@spacedust i only want the cordinates of geomarty with material property at those cordinate points...

R u trying to apply any computational techniques to ur waveguide structure for analysis ? I dont know how to get this data thru CST but if its a simple waveguide structure, then I think u can define them in Matlab directly..!

@spacedust: i got it... we can do it using NASTRAN file (meant to export FEM mesh).. at the very beginning they are giving me the name of material used and then the mesh coordinate.. .
