Thanks Peter – this is it.
Is there a way to set the material for the whole CPRISM without having to set it for each line (I don’t think so)? With the code you’ve supplied (thank you), a preceding MATERIAL command will only set the top and bottom materials.
Also, the ‘side_material’ listing at the command level seems redundant, as this has to be set for each coordinate line. Am I reading this right?
