Plot dialog: - "Units" (millimetres / inches) is the page setup's own unit: the offsets and the custom scale are shown in it, the stored ratio converts with it so the plotted result and the paper space's unit stay the same - "Custom: [paper] mm = [drawing] units" spells the picked scale in that unit and accepts a typed ratio, which selects the list's name for it or becomes a ratio entry of its own - "Hide paperspace objects" is the page setup's plot-hidden flag; it is no longer derived from the "Hidden Line" shade mode - "Save changes to layout" (paper layouts, on by default) writes the dialog into the layout when a plot is sent; previews never touch it - offsets are labelled in the page-setup unit and kept in millimetres in the file System variables (typeable, through SETVAR, listed by SETVAR ?): - PLOTOFFSET, PAPERUPDATE, PLOTROTMODE, PLOTTRANSPARENCYOVERRIDE and BACKGROUNDPLOT live with the persisted plot preferences: the plot origin counts from the printable corner unless PLOTOFFSET says the paper edge; a printer that does not list the sheet either warns or switches to its default sheet; transparency can be forced on or off; BACKGROUNDPLOT bit 1 is the dialog's background switch and bit 2 drives batch plots - CTAB and TILEMODE read and switch the current layout Tests cover every new control and variable; six new strings in all 21 locales; the Plot dialog grows to 940×690 for the two extra rows.

Page-setup fixtures saved by a commercial CAD application (2016 release, DXF
AC1027 and the matching DWG). Provided by Panos for the plotting parity track;
the drawing holds one 10 m line ($INSUNITS = 6, metres) and three paper
layouts, each with a viewport of that line and its dimension:

What the file establishes (see src/app/update/file.rs, plot_settings_from_dialog):
- A landscape sheet is written either as the driver's own landscape medium with rotation 0 (the PDF driver lists both orientations) or as a portrait medium with rotation 90 (system printers) — rotation is relative to the medium's orientation, and the medium's exact driver dimensions are kept.
- Margins (
40–43, mm) belong to the medium's own edges: the PDF driver's A4 has 5.79375 left/right and 17.79375 bottom/top. Layout limits (10/20) put the sheet at minus the displayed margins: at rotation 90 the medium's top margin (20.02) becomes the layout's left one, its left margin (5.00) the layout's bottom one. - Plot flags
70= 672 on every layout: draw viewports first, print lineweights, plot with plot styles — the "use standard scale" bit stays clear even with a standard code in75; the model tab (fit to paper) sets it. 147is142/143× 25.4 on millimetre page setups and142/143itself on inch ones.- An inch page setup over a millimetre paper space stores "1:1" as
1 in = 25.4 units(75= 16 kept).
