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

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

How these drawings were generated

These drawings were generated from the source 3D CAD geometry. The system analysed the model, selected relevant views, planned section cuts and generated drawing sheets in PDF, SVG and DXF formats.

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.
