+# N3XD
+
+Parametric CAD in the browser. Sketch it, constrain it, extrude it, then slice or
+simulate it without exporting through three other programs and a prayer.
+
+The geometry is real OpenCASCADE, not a WebGL impression of it, and the heavy
+lifting happens server side so your laptop fan can go back to doing nothing. It
+also speaks LLM out of the box, because "make that wall 2 mm thicker" is faster
+than hunting for the dimension that owns it.
+
+Live at [n3xd.io](https://n3xd.io).
+
+## The moving parts
+
+- **`ocp`** hand-written bindings to the OpenCASCADE geometry kernel, so Python
+  can talk to solids without the usual suffering.
+- **`assay`** the simulation engine. Mesh in, fields out. Tells you whether the
+  part survives before the real one does not.
+- **`forge`** the fabrication engine. Turns a model into layers, toolpaths and
+  G-code, permissively licensed so you can actually use it.
+- **`index`** the business layer. Accounts, projects, sharing, and the library of
+  parts and materials that keeps you from redrawing the same bracket twice.
+
+## Why can I not see any of this?
+
+These repos are private for now, mostly for security reasons and slightly
+because we would like to tidy up before company arrives. They go public soon.
