This command lets you choose the GiD mode you wish to work with (Preprocess or Postprocess), and the different visualization options in each mode:
Preprocessing: This command allows Mesh or Geometry visualization to be set.
The Toggle command changes from one visualization to another. If mesh visualization is selected and no mesh exists, you are asked to generate one.
Postprocessing: This command allows Graphs or Mesh visualization to be set.
This command allows you to move between default mesh visualization and graphs visualization.
