AutoCAD writes $ANGBASE in degrees (a drawing whose angles run clockwise from
north has 90.0); CADCraft read and wrote it as radians, so such a drawing's
angle base came in as 90 radians (about 116.6 degrees), turning typed angles,
polar tracking and angles shown in Properties. The reader now converts to
radians (the variable's unit), the writer back, and the DWG reader's hand-off
of the value in DXF form gives degrees.

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.
