Automating 3D Model Generation for CAD Systems
We developed an automated solution capable of generating accurate 3D models based on predefined configurations and calculations.
01
The challenge
The client faced inefficiencies in manually assembling 3D product models using CAD software. They needed an automated tool to generate 3D models based on provided calculations&configuration in commonly used open formats, leveraging native ZW3D files or exports like STL, STEP, or IGES.
02
Goals
The primary goals of the project
Automate the 3D model creation process for predefined parameters.
Ensure compatibility with widely adopted CAD file formats.
Optimize performance while maintaining high-quality output.
03
What We Did
Research
Evaluated several CAD and 3D libraries, including OpenSCAD, glTF-Transform, and OpenJSCAD to determine the most effective solution for the project’s needs. OpenJSCAD emerged as the best fit for its speed, native STL handling, and robust capabilities.
Optimization
Modified operations, such as cutting holes in raw materials versus assembling pre-shaped rail segments, to optimize the balance between production speed, resource efficiency, and overall operational effectiveness.
Development
Backend tool to assemble components (e.g., rails, trolleys) into a complete model based on configurations.
Integrated a 3D viewer using Three.js to enable real-time visualization and interactive exploration.
Added caching mechanisms to optimize repeated configurations and significantly reduce processing times.
Custom transformations to adjust rail lengths dynamically, ensuring correct placement of holes, threads, and other specifications using Boolean operations.
