Colour Display Options

A number of display options are available to colour regions and faces according to their media.

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 display 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 their assigned media.

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 colour of free space when viewed from the outside. When viewed from the inside (utilising a cutplane or after hiding faces) the colour is consistent with 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 (coating) for that wire.

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. For example, an object in free space will have the colour of free space (red by default) on the outside of the object.
