Draw a 3-dimensional view of the grid with the solution selected from the [DoF]-submenu giving the "height" of the grid points. If this drawing mode is selected there appears a little coordinate system in the upper left corner of the window. Clicking this coordinate system will allow to change the viewpoint by rotating via x-, y- or z-axis (press the corresponding key, and shift-key for backwards). Other keys are available for manipulating the viewpoint: u,v,w,p,0,1,2,3,*,h - try it. <ESC> will reset to the previous view, <RETURN> will accept. You must redraw your current solution explicitly to apply the new viewpoint.
