No A serious CAD tool with exact B-Rep geometry, boolean CSG, and STEP/IFC import and export requires a geometry kernel built by specialists, which vibe coding cannot produce.
What it would actually take: A real version needs a geometric modeling kernel (or licensing one like Parasolid, OpenCASCADE, or Manifold), robust tolerance-aware boolean operations, and ISO STEP and IFC schema parsers. This is multi-year work for experienced CAD and computational geometry engineers, plus extensive testing against real industry files.
Discussion
15 comments analyzed.
Competitors mentioned: Solidcraft, SolidWorks, FreeCAD, Dune3D, SolveSpace
Concerns raised: Fillet preview hangs or is extremely slow, Built on OpenCascade with tolerance drift and kernel limits, Lags behind Onshape; tooltips slow to appear, Boolean tool/target chosen by selection order only, Codebase is a single 16,000-line C++ file
Feature requests: Explicit tool and target selection for boolean operations, Faster tooltip display, Clarify which modeling kernel is used
