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 provides the primary orthographic projection, clearly showing the overall length, the taper of the toolholder, and the arrangement of the pull stud and collet.

Assembly - Left View

Assembly - Left View

Orthographic

The Left view is a circular cross-section that reveals the concentric bores and the internal diameter of the toolholder, which are critical for understanding the clamping mechanism.

Section A-A

Section A-A

Orthographic

This section cut through the center of the toolholder reveals the internal bore, the collet's internal geometry, and the wall thickness, which are not visible in the external views.

A — Asection_a · Section4
sheet_num: 4 · edges: 9

This section cut through the center of the toolholder reveals the internal bore, the collet's internal geometry, and the wall thickness, which are not visible in the external views.

  • 9 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: (18.879, 0, 0) · radius: 15

This detail magnifies the end mill's helical flutes and cutting edge, which are small but critical features for the machining 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 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.
