MD-11 Aircraft CAD Assembly

PARAMETRIC CAD / ASSEMBLY DESIGN / DRAWING RELEASE / BOM / EARLY STRUCTURAL WORKFLOW

My earliest full-aircraft design project. I built a parametric MD-11 model and assembly in SolidWorks, carried it into a drawing package and BOM workflow, and retained the native assembly, part, drawing, and neutral Parasolid artifacts.

INTERACTIVE

Drive the assembly parameters

Move the sketch parameters and the three-view rebuilds, the way a parametric assembly does. Suppress a part group to see the roll-up change, or explode the assembly.

This model needs JavaScript. The retained source artifacts are listed below.

↓ TAKE IT WITH YOU

Open the model yourself

The retained SolidWorks package and a neutral Parasolid export, so you can open the geometry in your own CAD seat instead of taking a screenshot on trust.

01 / SOURCE ARTIFACTS

What is actually retained

Assem1.SLDASMSolidWorks assemblyRetained native assembly artifact dated November 24, 2024.
MD11.SLDPRTSolidWorks partPrimary native part model retained with the project package.
MD11_Drawing.SLDDRWSolidWorks drawingDrawing artifact retained from the original CAD workflow.
MD-11 Plane.x_tParasolid geometry exportNeutral geometry export retained for downstream CAD interoperability.

02 / DESIGN WORKFLOW

How the aircraft model was built

1Model geometryBuild reusable parametric aircraft geometry instead of disconnected sketches.
2AssembleOrganize components into a complete aircraft assembly with controlled relationships.
3Check rebuildsMaintain model intent so changes propagate through the assembly.
4Release drawingsCreate the drawing package and structured bill of materials.
5Export geometryPreserve a neutral Parasolid representation for later reuse.

Mechanical-design scope

  • Full-aircraft parametric modeling in SolidWorks
  • 24-part assembly organization
  • Assembly mates, configurations, and rebuild-stable intent
  • Drawing release workflow with GD&T / PMI annotations
  • Bill of materials generation
  • Geometry prepared for downstream engineering analysis

Early engineering-analysis scope

  • Static, thermal, and modal FEA workflow
  • Representative 2.5g maneuver loading
  • Three structural hotspots identified during the study
  • Geometry, thickness, and fastener-layout iterations used to address weak regions
  • Academic design exercise, not OEM or certification analysis

Boundary: This is an academic CAD project and a record of my early mechanical-design development. It is not an OEM MD-11 model, an airworthiness artifact, or certification-level structural substantiation.
