A physical structure in [[EM.Cube]] in made up of a number of geometric objects you either draw in the project workspace or import from an external CAD model file. In all [[EM.Cube]] modules, you use [[CubeCAD]]'s common drawing tools and/or its import capability to construct your geometrical structure. In order to perform an electromagnetic simulation, you need to assign material properties to all of your CAD objects in the project workspace. The drawn CAD geometric objects are organized grouped together based on simply by their common color. They do not have any physical properties under one or more object groups or nodes . However, in the '''Navigation Tree'''. The grouping all of CAD objects is essentially based on their material composition and their associated boundary conditions.  Among [[EM.Cube]]'s computational modules, [[EM.Tempo]] is the most comprehensive in view of material variety offering. [[EM.Ferma]] and [[EM.Libera]] offer PEC and dielectric material groups similar you need to [[EMassign physical properties to each geometric object.Tempo]]. [[EM.Illumina]] offers PECIn these modules, PMC and impedance surfaces. [[EM.Terrano]] groups the geometric objects into material [[Block Types|block types]] that are characterized by their ray interaction properties. [[EM.Picasso]] groups objects based on their trace location (i.e. Z-coordinate) in the substrate layer hierarchy.grouped together
