FACE ORIENTATION
In 3D modelling, each face has a front and a back. Correct shading and lighting depend on the
front side (the normal) facing outward. If the face is flipped, it can cause shading issues or make
objects invisible in games or renders.
To Enable Face Orientation, follow these steps:
Step 1 Go to the 3D Viewport.
Step 2 In the top-right corner, click the Overlay button.
Step 3 Check the Face Orientation checkbox.
Blue faces = Front side (correct).
Red faces = Back side (flipped).
Step 4 On the top menu bar, click the Mesh option.
Step 5 From the dropdown list, hover over Normals to open the submenu.
Step 6 Select the Flip option from the submenu.
The selected faces will flip, changing their orientation.
LOCAL & GLOBAL AXIS
In 3D modelling, objects can move, rotate, or scale using two axis systems:
Global Axis: Refers to Blender’s main coordinate system. The X (red), Y (green), and Z (blue)
axes remain fixed for the entire scene.
Local Axis: Refers to an object’s personal axis, which moves and rotates along with the object.
