menu in the 3D view with the U key. Figure 7.13 shows a cropped
version of what you see, including the U-key menu. We'll work
with some of those other options later in this chapter, but for now
choose Project from View . When you do, the same mesh structure
that you see in the top view is transferred to the image window on
the left. It is an exact representation in 2D of the mesh structure
from the 3D view, like someone just took a picture of the 3D view.
To really see the effect, rotate the 3D view a bit so your room is
off-axis, then try Project from View again.

Note
A quick reminder. All operations in Blender are not only
accessible via their hotkeys (like U key for the Unwrap
menu), but also from the context-sensitive header menus
for each window, through the spacebar menu and search
box, and the Add Tool section of the T-key toolbar.

Before we continue, though, return to a top view and redo the
Project from View command so that your UV/Image Editor
window looks somewhat like the one in Figure 7.13 . Over in the
UV Editor (as we'll call it for short), notice the control structure.
It's basically the same as working with a mesh in the 3D view,
with the exception that you're working in 2D. So, no 3D rotation.
RMB select individual vertices. You can work in Vertex, Edge,
