View 3D objects as a wire frame

Hi All,

I have a 3D collada model of a transmitter tower. I cannot seem to be able to view it as a wireframe in ArcScene. It always has coloured faces with the option to turn on/off shading but I just want to see the line vertices that make up the model.

Is this even possible in Arscene? surely it must be?!

Hope someone can help.

Cheers,

Dave Brooks
