Time for action – going into Edit Mode
The difference between Object Mode and Edit Mode is a little confusing at first. You look at the cube, and it's hard to tell which mode you are in. However, don't worry; you'll quickly get the hang of it:
Open Blender. Zoom in to the cube so that it fills up most of the 3D View. You are going to look at it in more detail.
Now, press the Tab key. Press it several times. Note the changes in the 3D View and the changes in the 3D View header.
What just happened?
You opened Blender and zoomed in to the default cube. Then, you pressed the Tab key to go into Edit Mode. This mode lets you modify parts of an object; that is, the vertices, edges, and faces. You should have noticed three major differences: the cube is alternated between grey and orange, the header has changed, and the Tool Shelf has changed.
In Object Mode, there is an orange border around a gray cube. In Edit Mode, you see dots at every corner of the cube, and all the edges of the cube are highlighted...
