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 - Left View

Assembly - Left View

Orthographic

The left view provides a side profile that shows the depth of the base and the vertical alignment of the shaft, helping to define the mechanism's three-dimensional structure.

Section A-A

Section A-A

Orthographic

The section cut reveals the internal bore of the vertical shaft and the connection point to the horizontal arm, showing how the components are assembled and supported.

A — Asection_a · Section5
sheet_num: 5 · edges: 13

The section cut reveals the internal bore of the vertical shaft and the connection point to the horizontal arm, showing how the components are assembled and supported.

  • 13 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 Cdetail_c · base_view: Front
anchor: (0, 0, 0) · radius: 15

This detail magnifies the pivot point where the horizontal arm connects to the vertical shaft, highlighting the bearing and the precise alignment required for smooth operation.

  • 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 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.
