## What it is
CAD Sketcher is a constraint-based sketcher extension for Blender that lets users create precise 2D shapes using geometric constraints like tangent, distance, angle, and equal. Sketches remain editable and convert to beziers or mesh through a fully non-destructive workflow.

## Use cases
- draw precise 2d sketches with cad constraints in blender
- create parametric shapes with tangent and angle constraints
- convert constraint sketches to editable mesh or beziers
- bring cad-like precision modeling to blender mesh workflows
- non-destructive sketch editing with geometry nodes
- dimension-driven 2d drawing inside blender

## When to avoid
- you need a full parametric CAD package with assemblies or 3d constraints
- you work on production files without backups, since the project is explicitly experimental
- you use a Blender version older than 5.0

## Facets
- artifact type: plugin
- maturity: experimental
- function: graphics, simulation, ui-components
- domain: graphics, developer-tools
- platform: cross-platform, python
- tags: blender-addon, cad, parametric-modeling, constraint-solver, 3d-modeling, geometry-sketching, game-development
