Cubit 15.7 User Documentation
Now you may begin generating the geometry to be meshed. You will create a brick of width 10, depth 10 and height 10. The width and depth correspond to the x and y dimensions of the object being created. The "width" or x-dimension is screen-horizontal and the "depth" or y-dimension is screen-vertical. The height or z-dimension is out of the screen. The command to create this object is:
cubit> create brick width 10 depth 10 height 10 (OR)
cubit> create brick x 10
The cube should appear in your display window as shown below:
