How to extrude a camera 3D model?

To extrude a camera 3D model, select a flat 2D face or edge (e.g., lens outline, body panel) in 3D software, then use the extrude tool to extend it along an axis (usually Z) for depth. Extrusion turns flat shapes into 3D—like a flat lens becoming a cylindrical barrel or a grip into a raised, ergonomic part. Tools (Blender’s E key, SketchUp’s Push/Pull) let you adjust distance/direction for details (buttons, ports, main body). For beginners, start with simple parts (e.g., front panel)—small steps make shaping easier without complexity.
