Three review findings against SECTION 19 on the live engine, each measured
on AutoCAD 2026 in a scratch document with the operator's BACKGROUNDPLOT=2:
- plot_style_list read Preferences.Files.PrintStyleSheetPath; the ActiveX
member is PrinterStyleSheetPath, so the AttributeError was swallowed and
every row came back installed=None. Renamed in the backend, the server
docstring and the test fake (which faked the same wrong name). Live: 13
rows, all 9 catalogue ctb files installed, four .stb files as installed.
- ComBackend.drawing_export_pdf returned ok before any file existed under
background plotting, so batch_plot died on path.stat() with an unhandled
FileNotFoundError and a later foreground plot raised E_FAIL. The export
now sets BACKGROUNDPLOT=0 around PlotToFile (restored after), honours the
method's bool and reports ok only with the file on disk (bytes included).
batch_plot turns a backend RuntimeError or a phantom ok into a per-row
ok:false, keeping the rows already plotted.
- With a sheet current, the Model row was that sheet plotted again: the COM
export switched tabs only when a layout was named. layout=None now makes
Model current (restoring the tab), and batch_plot names every layout,
Model included, so both engines plot the tab the row is labelled with.
Live: Model row /Title (Model) at 210x297 beside the A3 sheet, the active
tab and BACKGROUNDPLOT restored.
