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 primary assembly of the knee joint, including the central hexagonal bolt, the main housing, and the overall profile, which is essential for understanding the component's layout.

Assembly - Left View

Assembly - Left View

Orthographic

The Left view provides a profile view showing the depth and internal features such as the cylindrical bores and the connection points, which are not visible in the Front or Top views.

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

The detail view magnifies the central hexagonal bolt and its surrounding flange, highlighting the critical fastening point and the precision required for assembly.

  • 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 2 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 0 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.
