 Current Status
 ==============
 
-JSketcher is a parametric 3d modeler employing a 2D constraint solver for sketches and the feature/history metaphor to build models. The 2D constraint solver is completely written in javascript/typescript and is implemented in both the 3D CAD and the 2D sketcher. Originally developed by xibyte to make models for 3d printing. Today JSketcher provides a rich set of tools for visualizing, selecting/interacting with 3D geometry, tracking and storing model history all built on the foundation of the 2D sketcher engine and employing OpenCascade for solid modeling operations.
