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 arrangement of the cooling fins and the central fan, providing a comprehensive understanding of the heatsink's profile and airflow path.

Assembly - Left View

Assembly - Left View

Orthographic

The left view offers a side perspective that highlights the depth and the internal structure of the heatsink, including the fan's position relative to the fins.

Section A-A

Section A-A

Orthographic

This section reveals the internal structure of the heatsink, including the thickness of the fins and the internal cavity for the fan, which are not visible in external views.

A — Asection_a · Section5
sheet_num: 5 · edges: 20

This section reveals the internal structure of the heatsink, including the thickness of the fins and the internal cavity for the fan, which are not visible in external views.

  • 20 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: (51.14, 185.61, 858.86) · radius: 10

This detail magnifies the fan's mounting area, showing the precise location and dimensions of the fan's attachment points.

  • 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 3 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.
