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 - Top View

Assembly - Top View

Orthographic

Shows the hexagonal mesh pattern, overall square dimensions (130×130mm), and the four corner mounting hole positions and pattern spacing. Critical for understanding the grid layout and hole placement.

Assembly - Front View

Assembly - Front View

Orthographic

Reveals the overall height (10mm), the profile of the mounting holes with countersink/counterbore geometry, and the edge detail. Essential for understanding vertical dimensions and hole depth specifications.

Section A-A

Section A-A

Orthographic

Vertical section through the center reveals the internal bore geometry of the M4 holes, showing the counterbore (Ø8mm) and countersink (Ø4.5mm) depths, wall thickness, and the overall 10mm height profile.

Vertical section through the center reveals the internal bore geometry of the M4 holes, showing the counterbore (Ø8mm) and countersink (Ø4.5mm) depths, wall thickness, and the overall 10mm height profile.

  • 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: Top
anchor: (117.5, 117.5, 0) · radius: 25

Magnifies one corner mounting hole to clearly show the counterbore and countersink geometry, hole diameter (M4 ≈ 4.5mm), and the counterbore diameter (8mm) for proper fastener specification.

  • 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.
