Create, modify and constrain 2D sketches in Fusion
Lesson details
Learning outcome
I can create 2D constrained sketches using Fusion.
Key learning points
- Fusion is a sketch based CAD application, based on solid parametric modelling.
- In Fusion, sketches are 2D geometric representations used to create 3D solid models.
- There are four sketch tools in Fusion: create, modify, constraints and palette.
- Constraints should be applied to sketches to avoid design errors.
Keywords
Sketch - creating basic shapes like lines, circles, rectangles, and text
Modify - using tools such as fillet, trim, and offset
Constraints - used to control sketch relationships and avoid design errors
Common misconception
Physical sketching is the same as sketching in parametric CAD.
Sketches in parametric CAD need to be constrained in order to create accurate and error free models.
Teacher tip
Pupils will complete a mix of creating their own sketches and sketching within the greenhouse model. Allow time for pupils to become familiar with the sketching tools.
Equipment
Access to Fusion. Downloadable greenhouse model.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
