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 - Front View

Assembly - Front View

Orthographic

The Front view clearly shows the V-angle between the cylinder banks and the relative positioning of the pistons and crankshaft, which is essential for understanding the engine's geometry.

Assembly - Top View

Assembly - Top View

Orthographic

The Top view provides a clear layout of the three cylinders on each side of the V, showing the crankshaft alignment and piston arrangement across the full length.

Assembly - Left View

Assembly - Left View

Orthographic

The Left view reveals the depth and stacking of components along the X-axis, particularly the crankshaft journals and connecting rod alignment.

Section A-A

Section A-A

Orthographic

This section cut along the Y-axis reveals the internal bore of the crankshaft and the connecting rod bearings, showing the internal clearance and fit.

A — Asection_a · Section5
sheet_num: 5 · edges: 24

This section cut along the Y-axis reveals the internal bore of the crankshaft and the connecting rod bearings, showing the internal clearance and fit.

  • 24 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
Detail Bdetail_b · base_view: Front
anchor: (0, 0, 0) · radius: 15

This detail magnifies the piston pin bore and its connection to the connecting rod, which is critical for assembly and manufacturing.

  • Detail-view anchor selected by the AI planning stage
  • Use with sheet PDF/SVG for local feature inspection
  • Validate critical dimensions against source CAD before release

AI Transparency

How these drawings were generated

The Marathon 3D→2D pipeline rendered 4 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. 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.
