The best way to move a face in a 3D model is to use your software’s transform tools (e.g., translate, grab) to select the face and adjust its position along the X/Y/Z axes while preserving the model’s topology (edge/vertex structure).
This avoids distorting the model—key for tasks like refining a character’s facial features or modifying a product’s surface.
For beginners, try Blender’s free “Grab” tool (press G) with a selected face; hold Shift to snap to gridlines for precise movement.
