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.

What is actually retained

Assem1.SLDASMSolidWorks assemblyRetained native assembly artifact dated November 24, 2024.

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

Later structural work moved from broad aircraft modeling into traceable fitting substantiation, nonlinear FEA, allowables, fatigue, damage tolerance, and verification evidence.

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.
