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 overall arrangement of the crankshaft, pistons, and connecting rods, providing the primary orthographic perspective of the engine's longitudinal layout.

Assembly - Top View

Assembly - Top View

Orthographic

The Top view reveals the circular bores of the cylinders and the camshaft, offering critical information about the engine's transverse dimensions and component alignment.

Assembly - Left View

Assembly - Left View

Orthographic

The Left view provides a side profile of the engine, showing the height of the cylinder block and the relative positioning of the crankshaft and camshaft, which is not fully visible in the Front or Top views.

Section A-A

Section A-A

Orthographic

This section cut reveals the internal structure of the crankshaft and the bore of the cylinders, showing the internal passages and the arrangement of the crankshaft journals.

A — Asection_a · Section5
sheet_num: 5 · edges: 25

This section cut reveals the internal structure of the crankshaft and the bore of the cylinders, showing the internal passages and the arrangement of the crankshaft journals.

  • 25 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 view magnifies the piston and connecting rod assembly, highlighting the critical connection point and the dimensions of the piston pin.

  • 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.
