From this new database, we will first generate points 1 and 2.
Next, we will create points 1 and 2. To do this, we will use an Auxiliary Window that will allow us to simply describe the points by entering coordinates. It is accessed by the following sequence: Utilities->Tools->Coordinates window
Then, from the Top Menu, select Geometry->Create->Point
In the coordinate window opened previously, enter the coordinates of point 1 in the "x", "y", "z" entries and click Apply or press Enter on the keyboard.
And create point 2 in the same way, introducing its coordinates in the Coordinates window.

NOTE: The size of an element with two nodes is the length of the element. For, surfaces or volumes, the size is the mean length of the edge of the element.
In this example, the size of the element is defined in concordance with the length of the line, chosen for this case as size 1. Click OK.
Once the mesh has been generated a window with the mesh information appears. Click View mesh.
Automatically GiD generates a mesh for the line. Pressing 'View mesh' the finite element mesh is presented on the screen.
The mesh is formed by ten linear elements of two nodes. To see the numbering of the nodes and mesh elements, select from the Mouse Menu: Label->All on, and the numbering for the 10 elements and 11 nodes will be shown, as below.
Once the mesh has been generated, the project should be saved. To save the example select from the Top Menu: Files->Save.
The program automatically saves the file if it already has a name. If it is the first time the file has been saved, the user is asked to assign a name. For this, an Auxiliary Window will appear which permits the user to browse the computer disk drive and select the location in which to save the file. Once the desired directory has been selected, the name for the current project can be entered in the space titled File Name. Save it as initiation.gid. 
NOTE: Next, the manner in which GiD saves the information of a project will be explained. GiD creates a directory with a name chosen by the user, and whose file extension is .gid. GiD creates a set of files in this directory where all the information generated in the present example is saved. All the files have the same name of the directory to which they belong, but with different extensions. These files should have the name that GiD designates and should not be changed manually.
Each time the user selects option save the database will be rewritten with the new information or changes made to the project, always maintaining the same name.
To exit GiD, simply choose Files→QuitFiles → Quit.
To access the project that we have just created, simply start GiD again and select from the Top Menu: Files->Open. An Auxiliary Window will appear which allows the user to access and open the directory initiation.gid.
