MVP 0.1

MVP 0.1 focuses on the editor core:

• Start the Avalonia desktop app.
• Pan and zoom a millimetre canvas.
• Draw lines from two points.
• Draw circles from three circumference points.
• Draw arcs from start, through, and end points.
• Select and delete entities.
• Undo and redo document mutations.
• Save and load the native JSON project format.
• Export LINE, CIRCLE, and ARC entities to DXF.

MVP 0.2 adds the manual reference-image layer:

• Import a raster image as a locked background reference.
• Display the reference below CAD entities.
• Adjust opacity independently of geometry.
• Lock and unlock the reference.
• Edit reference X/Y origin, scale, and rotation manually.
• Save and reload reference metadata in the native JSON project file.

Deferred work:

• Calibration sheet generation.
• OpenCV marker detection.
• Assisted fitting tools.
• Constraint and dimension systems.
