Could you build this?
Partial A Figma-like canvas UI is easy to vibe-code, but a full 2D architectural CAD tool requires robust computational geometry algorithms and precision snapping engines.
What it would actually take: The application typically requires a TypeScript frontend with a WebGL or WebGPU canvas renderer, backed by a computational geometry core (often compiled via WebAssembly from C++ or Rust). The hard problems include robust 2D polygon boolean operations, geometric constraint solving, R-tree spatial indexing for CAD-scale object counts, and accurate DXF/DWG file export. This requires dedicated expertise in CAD algorithms and computational geometry.
