Polar points and angle prompts read bare numbers in AUNITS (explicit d/r/g, deg-min-sec and bearings still work) and measure directions from ANGBASE in the ANGDIR sense; `d<<a` (degrees) and `d<<<a` (AUNITS) measure from +X counterclockwise. XLINE Reference turns per ANGDIR; included angles and sweeps take the units only. ANGBASE is held in radians like $ANGBASE in DXF; SETVAR reads and reports it in degrees. JSON params keep their meaning. Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>
