ADM Activity 4.3.1

CAD Design of the Aerospace Component

Create a fully constrained, machinable Fusion model for the UAV payload sensor mounting bracket.

Learning targets

Today You Will Learn To

  • Create a parametric model that satisfies the approved interface.
  • Apply tool-compatible radii, edge distances, wall thicknesses, and stock limits.
  • Use physical properties and measurements to evaluate the design.
Manufacturing context

Why This Matters

The aerospace component is designed in Fusion so the same file can move directly from the Design workspace into the Manufacture workspace. Modeling choices must support reliable Fusion toolpaths, one approved setup, practical workholding, and inspection on the completed part.

Learning sequence

Learn Before You Build

Complete these steps in order. Record the requested notes or evidence before moving to the graded activity.

10 min

1. Reopen the approved requirements

Highlight every interface dimension, clearance, feature, mass target, stock limit, and DFM rule that must appear in the model.

10–15 min

2. Review parametric sketching

Use the Autodesk sketch-dimension resource to review fully constrained geometry and dimension-driven design intent.

20 min

3. Follow a teacher modeling demonstration

Observe the recommended feature order: base stock, mounting interfaces, payload interface, clearance, pockets, radii, and finishing features.

15 min

4. Complete a model-readiness practice check

Use a sample model to locate an underconstrained sketch, unsupported feature, wrong material, or unmachinable internal corner.

Detailed activity procedure

Create the Parametric Aerospace Component Model

  1. 1
    Create the Fusion project and descriptive file name. Record the first design revision and verify the assigned unit system.
  2. 2
    Create or activate a single component for the aerospace bracket and identify the model origin and primary datum plane.
  3. 3
    Create user parameters for the major interface dimensions, stock thickness, hole spacing, pocket offset, wall thickness, and cutter-compatible radius when directed.
  4. 4
    Sketch the primary airframe interface from the approved datums. Add constraints before adding dimensions.
  5. 5
    Add the payload or sensor mounting interface using the approved hole pattern and alignment requirements.
  6. 6
    Add cable, connector, fastener, and adjacent-component clearance geometry.
  7. 7
    Create the exterior contour and base thickness within the approved stock boundary.
  8. 8
    Add weight-reduction pockets or openings while maintaining wall thickness, edge distance, and tool-access requirements.
  9. 9
    Apply tool-compatible internal radii, fillets, or chamfers only where approved.
  10. 10
    Assign the approved material and record the Fusion-estimated mass or physical properties.
  11. 11
    Inspect the timeline, component structure, sketch status, feature names, and warning symbols. Correct all unresolved errors.
  12. 12
    Run the DFM Analyzer and complete the manufacturability checklist.
  13. 13
    Complete a peer review against the requirements and interface-control sketch.
  14. 14
    Save the approved CAD revision for drawing and CAM. Later changes require a new revision and renewed downstream verification.
Required checkpoints

Stop and Verify Before Moving On

Checkpoint A — Interface model

Airframe, payload, fastener, and clearance features match the approved requirements.

Checkpoint B — Parametric model

Sketches are fully constrained and key dimensions use approved parameters.

Checkpoint C — CAD release

DFM audit, material, mass, and peer review are complete.

Safety and process control

Required Operating Habits

  • Use only teacher-approved files, tools, stock, speeds, feeds, and procedures.
  • Preserve the last verified working file or code version.
  • Stop immediately for unexpected motion, unusual sound, vibration, loose workholding, tool damage, or an unclear condition.
  • Do not operate the CNC mill without the required certification, permission, and supervision.
  • Record failed trials, defects, and interventions honestly.
Quality check

Before You Submit

  • All critical interface dimensions are driven by parameters or dimensions.
  • The model fits inside the assigned stock.
  • No unsupported feature requires an unavailable tool or setup.
Student deliverables

What You Submit

  • Final parametric CAD model
  • Fully constrained sketch evidence
  • Mass or physical-property evidence
  • Completed manufacturability checklist
  • Peer-review notes and revision record
Fusion file standard

Design-to-Manufacture File Organization

  • Create the component in the Fusion Design workspace using the approved document units.
  • Use one clearly named component and fully constrained sketches.
  • Name important sketches and features so they can be selected reliably in Manufacture.
  • Preserve the approved design version before creating or revising CAM operations.
  • Keep the same Fusion file for CAD and CAM unless the teacher directs a separate manufacturing model.
