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 - Front View

Assembly - Front View

Orthographic

The Front view provides a clear representation of the engine's axial compressor and turbine stages, showing the internal blade arrangements and overall diameter.

Assembly - Top View

Assembly - Top View

Orthographic

The Top view reveals the engine's longitudinal layout, including the fan, compressor, combustion chamber, and turbine, allowing for the visualization of the entire engine's length and component alignment.

Assembly - Left View

Assembly - Left View

Orthographic

The Left view offers a side profile of the engine, showcasing the fan inlet, core length, and exhaust nozzle, which is essential for understanding the engine's overall dimensions and spatial relationships.

Section A-A

Section A-A

Orthographic

This section cut along the Y-axis reveals the internal structure of the compressor and turbine stages, showing the blade arrangements and internal passages.

Section B-B

Section B-B

Orthographic

This horizontal section cut reveals the internal combustion chamber and turbine components, providing insight into the engine's internal flow paths and structural integrity.

A — Asection_a · Section5

AI Transparency

How these drawings were generated

The Marathon 3D→2D pipeline rendered 5 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 2 section cuts to expose critical internal features. It also selected detail-view anchor points for local manufacturing-critical regions. 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.
