A PDF, an EPS or .ai without ruler units, a raster image, a metafile, an Affinity file or an importer plug-in's document opened (and reverted) in points whatever the General unit was. They now open in the General unit, as the reference app opens files that record no unit. Native, SVG and DXF files and a .ai or EPS with %AI5_RulerUnits keep their own units. Only the displayed units change, not the art.

//! Units (Preferences ▸ Units): the unit every length the UI shows and reads is in.
|
|
//!
|
|
//! General (rulers, positions, sizes, dialog distances, canvas readouts) is the active document's
|
|
//! units, so they travel with the file: Document Setup (`document.setUnits`) changes them, and
|
|
//! Preferences ▸ Units ▸ General changes them too and is also the units new documents start in (and
|
|
//! the unit shown while no document is open). Stroke (weights, dashes), Type (sizes, leading,
|
|
//! baseline shift) and East Asian Type (the only
|
|
//! preference that offers Q and Ha, and no field reads it yet) are application preferences. Typed values with a unit
|
|
//! ("5 mm", "12 pt", "13 Q") work in any unit.
