      3D model using Extrude and the Timeline in Fusion

      Lesson details

      Learning outcome

      I can create 3D bodies using Fusion.

      Key learning points

      1. The Browser lists all objects and data in the assembly.
      2. In the Fusion Design workspace, the Extrude command lets you add or remove depth from a sketch.
      3. New bodies can be created or modified using Extrude.
      4. Material can be added or removed using Extrude.
      5. Extrudes and sketches can be edited using the Timeline.

      Keywords

      • Extrude - removing or adding depth from a sketch profile

      • Component - a container for bodies, sketches and other design elements with its own timeline

      • Body - a single continuous shape

      • Join - combining new features with existing bodies

      Common misconception

      A sketch is always needed to be able to use the Extrude command in Fusion.

      Users can extrude from component faces and existing solid bodies.

      Teacher tip

      Pupils will complete a mix of creating their own extrudes and extruding within the greenhouse model. Allow time for pupils to become familiar with the extrude command.

      Equipment

      Access to Fusion. Downloadable greenhouse model.
