Colour Display Options

A number of display options are available to colour regions and faces according to its medium.

On the 3D View context tab, on the Display options tab, in the Style group, click the Colour icon.
Table 1. Colour display options.
Icon Icon text Description
Element normal All parts are drawn with the same colour. The two sides of faces are coloured differently to indicate the normal direction of the faces.
  • On the geometry, the normal side of each element is coloured green, while the reverse side is coloured red.
  • On the mesh, the normal side of each element is coloured blue, while the reverse side is coloured brown.
Region medium Regions are coloured according to its assigned medium.

Surface mesh elements are coloured on each side according to the medium on that side of the face.

For example, when viewing the mesh of a dielectric / metallic object, the entire object has the free space colour when viewed from outside, but the view from inside (utilising a cutplane or after elements of the region boundary have been deleted) is the colour of the dielectric / metallic medium of the inside region.

When viewing the geometry, regions are displayed using the colour of the internal medium (whether viewed from outside or inside the region). If the display of the segment radii and coatings are activated on wire mesh elements, these are coloured according to the core medium or the layered medium defined as a coating for that wire respectively.

Face medium The faces are displayed according to the medium of each face.

When viewing the mesh, the display of segment radii is automatically activated for wire elements in the mesh and these are coloured according to the core medium. (The segment radii display may be manually deactivated if required, in which case no specific colouring will be shown for wire elements in the mesh.)

Face normal medium The faces are displayed according to the material colour on the two sides of the face. As an example, an object in free space will have the colour of free space (red by default) on the outside of the object.
