## What it is
JSketcher is a parametric 2D and 3D CAD modeler written in pure JavaScript/TypeScript that runs entirely in the browser with no server-side component. It combines a 2D geometric constraint solver, feature-history-based 3D modeling, and OpenCascade (via wasm) for solid BREP boolean operations.

## Use cases
- create parametric 3D models in the browser
- sketch 2D profiles with geometric constraints
- design parts for 3D printing and export to STL
- build CAD models with feature history and named dimensions
- measure and dimension 2D drawings
- run a CAD tool without installing desktop software

## When to choose
- you need a browser-based parametric CAD tool with no server backend
- you want constraint-driven 2D sketching feeding into 3D solid modeling
- you need STL/SVG/DWG export for 3D printing workflows
- you want to embed or extend an open-source CAD kernel in JavaScript

## When to avoid
- you need production-grade CAD interoperability with STEP or native CAD file formats
- you require a mature, fully-licensed commercial CAD package
- you need offline desktop performance for very large assemblies

## Facets
- artifact type: application
- maturity: active
- function: simulation, graphics, gui, wasm
- domain: computer-vision, graphics, developer-tools, cross-platform
