ℹ️

These are 2D engineering drawings derived from the 3D CAD geometry. Verify critical dimensions against the source model before manufacturing.

🤖

Views, section cuts, and detail areas were selected by AI based on analysis of 6 rendered views of the 3D model.

AI Drawing Analysis

What the AI Decided & Why

The cards below explain how the generated drawing outputs and assets connect to the final technical sheets.

Assembly - Top View

Assembly - Top View

Orthographic

The top view reveals the spanwise extent and uniformity of the airfoil, confirming its rectangular planform.

Assembly - Left View

Assembly - Left View

Orthographic

The left view provides a side profile that emphasizes the thickness distribution and leading/trailing edge geometry.

Section A-A

Section A-A

Orthographic

The section cut reveals the internal thickness distribution and curvature of the airfoil, which is essential for structural and aerodynamic analysis.

A — Asection_a · Section5
sheet_num: 5 · edges: 7

The section cut reveals the internal thickness distribution and curvature of the airfoil, which is essential for structural and aerodynamic analysis.

  • 7 resolved edges in sheet geometry
  • See technical_drawing_simple.pdf, sheet_N.pdf, and svg/ for full graphical context
  • Verify critical dimensions against the source CAD before manufacturing

AI Transparency

How these drawings were generated

The Marathon 3D→2D pipeline rendered 3 views of the 3D CAD model and passed them through our AI analysis engine.

The AI reasoned about the geometry, selected view candidates, and planned 1 section cut to expose critical internal features. The final drawing configuration was then generated automatically for sheet outputs in SVG, DXF, and PDF.

0 dimension references were mapped across sheets, with per-sheet labels, views, and extracted edge geometry.

These are 2D engineering drawings, not 3D files. Dimensions are extracted from the 3D geometry and should be verified against the source model before use in manufacturing.
