Fusion CAD Level 1

Study Guide

Prepare to build simple, organized, editable Fusion parts using sketches, dimensions, constraints, and basic solid features.

1. Fusion workflow mindset

Fusion models should be organized, editable, and based on design intent.
Parametric modeling means dimensions and features can be changed later.
A good CAD model is not just the right shape; it is built in a way that can be revised.
Use simple, stable steps rather than one messy sketch or feature.
Save work early and often in the correct project location.

2. Projects and file organization

Create or use the correct project folder before modeling.
Name files with project, part, version, or assignment context.
Avoid vague names like “part,” “final,” or “new design.”
Keep related files together so teammates and the teacher can find them.
Use version history and save milestones when making major changes.

3. Starting sketches

Choose the correct plane or face for the sketch based on the part orientation.
Use the origin and axes intentionally when symmetry or alignment matters.
Sketch simple geometry first, then add constraints and dimensions.
Closed profiles are needed for many solid features such as extrude.
Finish the sketch before creating a 3D feature from it.

4. Dimensions and constraints

Dimensions control size and location.
Constraints control relationships such as horizontal, vertical, perpendicular, parallel, coincident, tangent, equal, and concentric.
Fully defined sketches are more predictable and easier to revise.
Do not drag sketch geometry as a replacement for dimensioning it.
If geometry turns red or errors appear, stop and fix the constraint or dimension issue.

5. Solid features

Extrude turns a closed sketch profile into a 3D solid or cut.
Use join, cut, new body, or new component intentionally.
Fillets and chamfers modify edges and should be sized based on design intent.
Hole features are often better than manually sketching circular cuts for standard holes.
Keep feature order logical in the timeline.

6. Editing and design intent

Edit sketch dimensions or feature settings instead of deleting and rebuilding when possible.
Use the timeline to understand the order of features.
Changing an early sketch can affect later features.
Build with symmetry, origin alignment, and constraints when they make future edits easier.
Rename important sketches, bodies, or components when it improves organization.

7. Inspection and communication

Use inspect/measure tools to verify size, distance, diameter, and clearance.
Use section analysis or view controls when needed to check interior features.
Orbit, pan, zoom, and view cube controls help inspect geometry from different angles.
Take screenshots or exports only after confirming the model is saved and correct.
CAD models should match the design requirements, not just look close.

8. Exporting and sharing

Export the correct file type for the task: STL/3MF for 3D printing, DXF for some 2D cutting workflows, or native/project files for editing.
Check units and orientation before exporting.
Do not export unfinished or unsaved models as final deliverables.
Use clear filenames for exported manufacturing files.
Keep editable CAD files separate from exported manufacturing files.

Hands-on performance checklist

To earn the badge, students must create an organized Fusion part with a controlled sketch, dimensions/constraints, at least one solid feature, a successful edit, and proper save/export behavior.
