Time for action — using the global axis and local axis
We discussed the global and local axes. It's kind of an abstract concept until you use it. Here we can see it:
- Select New in the file menu.
- With the cursor over the camera, click theRMB to select it. Note the 3D manipulator and that the Z axis (in blue) is straight up. You can press 5 to toggle to Ortho mode to confirm that the Z axis is pointing up.
- Move the mouse over the Orientation selector in the 3D View header, outlined in the previous screenshot. Note that it says Global. Move the mouse up the Orientation pop-up menu and select Local with theLMB. Note which direction the Z axis is pointing now.
- Change from Local back to Global and back several times, noting the change in direction.
