Modelling Techniques

Start from primitives

Most models start as simple shapes: cube, cylinder, sphere, plane. Box modelling shapes a primitive step by step into the final object.

Core operations

Edge flow and topology

Good topology uses mostly quads with loops that follow the shape. It subdivides smoothly, deforms well when animated and is easy to edit. Avoid long thin triangles and many-sided n-gons on curved surfaces.

Modifiers: non-destructive tools

Modifiers change a model without destroying the original geometry:

• Mirror: model half, see both (symmetrical objects and characters).
• Subdivision Surface: smooth a low-poly cage.
• Array: repeat objects (fences, stairs, chains).
• Boolean: add, subtract or intersect shapes (holes, cutouts).
• Solidify: give thickness to a surface.
• Bevel: round edges procedurally.

Keep modifiers live while working; apply them only when needed (for example before exporting for printing).

Hard-surface vs organic

• Hard-surface (products, machines, furniture): precise shapes, bevels, booleans, supporting edge loops.
• Organic (characters, plants): sculpting and smooth subdivision with flowing topology.

Reference

Model from references: photos, measurements, or orthographic drawings (front, side, top) placed as background images. Guessing proportions is the most common beginner problem.

Exercise

Model a simple mug from a cylinder: inset and extrude the inside, add a handle by extruding faces along a path, bevel the rim, add a Subdivision Surface modifier with supporting loops to keep the rim crisp.
