Lesson Details
Key learning points
- 2D shapes can be extruded to create a 3D object.
- 3D models are composed of faces, edges and vertices.
- Additional geometry can be added to a model using the loop cut tool.
- Materials can be applied to individual or groups of faces.
Common misconception
3D models are all made up of simple shapes that are scaled, moved and rotated.
Having only previously used object mode, learners may be unaware that geometry such as vertices, edges and faces can all be directly modified in edit mode. Working in edit mode gives a modeller greater freedom to create more complex models.
Keywords
Extrude - to transform a 2D shape into a 3D object by extending it along a path or direction
Face - a surface made up of three or more edges
Edge - a line connecting two vertices
Vertex - a point where two or more edges or lines meet
