In the preprocessing part of GiD there are two basic modes the user can work with: geometry and mesh. Just in order to see how the mode can be changed we are going to generate a mesh with all the default parameters.
- . Select Mesh->Generate mesh... The following window should appear.
- . Click OK and wait for the mesh generation. Once the mesh is generated, a window pops up and shows the user the result from the mesh generation.
- . Click on 'View mesh' option, and the following visualization of the model should appear:
Now we are in 'mesh' mode. Changing the render mode user can see that the color of the mesh entities also follows the Layer colors.
Selecting View->Mode->Geometry user can change to the geometry mode again. The 
icon in the toolbar switch between both modes
