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

Primary elevation view showing the full vertical extent of the crankshaft, all journal and crankpin positions, counterweight profiles, and overall length. Essential for understanding the axial arrangement and spacing of components.

Assembly - Top View

Assembly - Top View

Orthographic

Plan view revealing the circular cross-section of the main shaft, the radial arrangement of crankpins and counterweights around the centerline, and the bolt hole pattern on the top flange. Critical for understanding rotational symmetry and radial positioning.

Assembly - Left View

Assembly - Left View

Orthographic

Side elevation showing the lateral profile of counterweights, crankpin throw distances, and the overall depth of the assembly. Complements Front view to confirm 3D spatial relationships and counterweight geometry.

Section A-A

Section A-A

Orthographic

Vertical section through the centerline (YZ plane at X=0) at mid-height reveals the internal bore/journal diameter, wall thickness of the main shaft, and the radial positioning of crankpins relative to the centerline. Essential for manufacturing the shaft bore and crankpin attachment geometry.

  • 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: Top
anchor: (0, 0, 0) · radius: 25

Magnified view of the bolt hole pattern on the top flange, showing individual hole diameters, spacing, and any threaded features. Critical for assembly and fastening specifications.

  • 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.
