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 propeller's profile, including the blade curvature, hub, and central cone, which are essential for understanding the overall shape and mounting interface.

Assembly - Top View

Assembly - Top View

Orthographic

The top view reveals the 3-blade symmetry, the circular hub, and the overall diameter, which are critical for assembly and dimensional verification.

Section A-A

Section A-A

Orthographic

This section cut through the hub reveals the internal bore diameter and wall thickness, which are critical for the motor adapter fit and structural integrity.

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.
