Is there a way to get the plate material density using OpenSTAAD?

I'm trying to develop the macro for automatic bill of material generation.

I’ve been stuck at getting plate properties.

Thickness is ok. I'm using ".Property.GetPlateThickness"

But I can't find a way to get the density of plate material.

Surprisingly there is no command such as for beam ".Property.GetBeamMaterialName" or ".Property.GetBeamConstants"

 

Do you have any ideas?
