Could you build this?
No Building a performant 3D CAD/brick builder in the browser requires deep knowledge of 3D graphics (WebGL/WebGPU/Three.js), spatial snapping math, connection topology graphs, LDraw specification parsing, and automated instruction generation.
What it would actually take: A production version requires an advanced WebGL/Three.js or custom renderer engine that can handle thousands of instanced brick meshes with zero lag. The most complex engineering challenge is creating a 3D connection and collision solver (stud-to-tube, technic pins, hinges) with exact snapping physics, as well as an algorithmic DAG compiler to automatically generate build step hierarchies and 2D instruction renders from 3D models. It requires graphics programming expertise and deep familiarity with LDraw file standards.
