# TraceCad Architecture
|
|
|
|
TraceCad is split into small .NET projects with one-way dependencies.
|
|
|
|
```text
|
|
TraceCad.App -> TraceCad.Core, TraceCad.Dxf
|
|
TraceCad.Dxf -> TraceCad.Core
|
|
TraceCad.Vision -> TraceCad.Core
|
|
TraceCad.Core -> no UI, OpenCV, or DXF package dependencies
|
|
```
|
|
|
|
## Coordinate Spaces
|
|
|
|
- Model space: millimetres, used for all stored CAD geometry.
|
|
- View space: screen pixels, used only by the Avalonia canvas.
|
|
- Export space: millimetres, mapped directly to DXF output.
|
|
- Reference space: reserved for calibrated background images in later phases.
|
|
|
|
## MVP Boundaries
|
|
|
|
MVP 0.1 intentionally excludes OpenCV, marker detection, automatic tracing, constraints, and dimensions. The first implementation proves deterministic CAD entity creation and DXF export.
