Web-Based CAD Engine: Industrial 3D Configurator with Intelligent Assembly Logic

Executive Summary

FiberDepth’s Industrial 3D Configurator is a high-performance R&D engine designed to bring complex engineering workflows into the browser. By combining WebGL with custom spatial assembly logic, we created a "Drag-and-Build" environment where structural profiles are treated as intelligent objects rather than just 3D models. This tool demonstrates our ability to bridge the gap between creative 3D rendering such as "Precision Snapping" and industrial design.

The Challenge: Beyond Static 3D

Standard 3D viewers are passive. The challenge for this project was to move from viewing to engineering. We needed to solve:

  • Precision Constraint Logic: Ensuring components don't just "touch" but mathematically align based on structural rules.
  • Spatial Orientation: Handling 90°, 180°, and 270° rotations while maintaining the "awareness" of connection points.
  • Performance: Maintaining smooth 60 FPS interactions while managing complex groupings and high-fidelity industrial profiles.

The Mathematical Engine: Engineering Precision

To ensure every assembly is manufacturing-ready, FiberDepth runs real-time spatial calculations based on industrial engineering standards:

1. Smart Snap Detection

Proximity

Calculates the exact distance between connection nodes to trigger a mathematical "lock."

d = √(Δx² + Δy² + Δz²)

2. Angular Awareness

Rotation

Recalculates attachment vectors during 90°, 180°, or 270° rotations to maintain structural integrity.

R_y(θ) =
[cos θ, 0, sin θ][0, 1, 0][-sin θ, 0, cos θ]

Features & Technical Implementation

FeatureTechnical ImplementationBusiness Value

Modular GroupingUsers can select, group, and duplicate entire structural modules.Speeds up the design of large-scale frames.
Scalable Profile LibraryDynamic support for 40x40, 40x80, 50x50, and 100x100 profiles.Highly adaptable to any manufacturer's catalog.

Key Features

  • Interactive Material Library: Drag and drop industrial profiles into the 3D workspace.
  • Intelligent Position Detection: System calculates offsets and shows real-time "join" previews.
  • Procedural Resizing: Scale components without stretching textures, maintaining visual accuracy.
  • Reusable Assemblies: Save frames as "Groups" to build larger structures efficiently.

The Technology Stack

Core: React Three Fiber (R3F) & Three.js
Rendering: Custom WebGL shaders for industrial material realism
Logic: Custom TypeScript-based spatial constraint system for 3D manipulation

Industrial Applications

  • Industrial Product Configurators: Machine part assemblies and enclosures.
  • Solar & Infrastructure: Mounting systems and modular structural designs.
  • B2B Furniture: Modular shelving and office partition systems.
  • Automation & Robotics: Custom frame builders for manufacturing lines.

Future Roadmap: The Path to "Spatial CAD"

  • BOM (Bill of Materials) Generation: Real-time cost and parts list export.
  • CAD Format Export: Direct output to .STEP or .OBJ for manufacturing.
  • Multi-User Collaboration: Real-time design sessions within the same 3D workspace.
