An empty scene displays a table (workbench) on top of a grid.
Your models will be built on the table. You can use the table and the grid as a reference point when moving in the scene. But you can also ask to have the table and grid not be displayed. (See chapter User Manual/Preferences/Interface.)
The scene includes all of the objects created in the same work space.
You will be able to display those objects in wireframe
mode or in shaded mode. (See chapter User Manual
Preferences/Interface/Work Space/Display Mode.)
The advantage of the shaded display mode is that it makes
manipulations more interactive and more realistic. The wireframe display mode is better
suited to precise work.
