This command allows one to represent a grid file obtained by using the Grids > Create Grid from Surface or Grids > Create Grid from Contour Lines tools. First, the program requests a grid file (ASCII or binary). The following dialog box is then displayed:
One can choose between two kinds of objects to draw a grid: The Polyface Grid option has the advantage of being quicker and the disadvantage that CAD sets a maximum limit on the number of vertices and faces. This is why the default option is 3D Faces.
In addition, there is the option of drawing the grid as an image and this method will allow us to create an Image from the grid file. To be precise, an image will be created in TIFF format.
By clicking the Select button, one can specify a layer other than the one proposed by the program. Clear Layer removes the objects from the layer before drawing the grid and Isolate Layer hides the drawing’s other drawing layers.
The Height Exaggeration parameter is used to multiply the grid’s height values in order to increase or decrease cell height differences and improve the viewing of relief. Lastly, once the representation is finished, the Zoom check box ensures the screen is framed on the grid area. In should be considered that the drawing is in three dimensions. It is therefore necessary to execute one of the CAD commands to change the viewpoint like, for example, VPOINT.
