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 layout of the four relay output terminals and the mounting holes, which are critical for installation and wiring. It also displays the height of the components, including the large cylindrical capacitor.

Assembly - Top View

Assembly - Top View

Orthographic

The Top view provides a comprehensive overview of the component placement on the PCB, including the ESP8266 module, the relay driver IC, and the various connectors. This view is essential for understanding the circuit layout and component interactions.

Assembly - Left View

Assembly - Left View

Orthographic

The Left view reveals the side profile, showing the height of the largest component (the cylindrical capacitor) and the thickness of the PCB. This is important for ensuring the module fits within a designated enclosure.

Section A-A

Section A-A

Orthographic

This section cut through the center of the module reveals the internal structure, including the PCB layers, the placement of the ESP8266 module, and the internal wiring, which are not visible in the external views.

A — Asection_a · Section5
sheet_num: 5 · edges: 41

This section cut through the center of the module reveals the internal structure, including the PCB layers, the placement of the ESP8266 module, and the internal wiring, which are not visible in the external views.

  • 41 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: Top
anchor: (45, 50, 13) · radius: 10

This detail view magnifies the area around the ESP8266 module, showing the fine-pitch pins and the associated surface-mount components, which are too small to be clearly seen in the main Top view.

  • 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.
