Start by planning your model: gather references, decide scale and purpose. In 3ds Max, set units, create basic shapes (box, plane, cylinder) and block out the form. Use Editable Poly to refine: move vertices, edges, and polygons to shape details. Apply symmetry for balanced models. Use modifiers like TurboSmooth for smoothness and Chamfer for clean edges. Keep topology clean with quads and proper edge flow. Add details step-by-step, not all at once. Use UV Unwrap for texturing, then apply materials. Finally, optimize, check smoothing groups, and export in the required format. Practice consistently to improve speed and quality.
