The Model layout was written with the default page setup, whose "layout"
plot area is plot type 5, "Layout information" (DXF Reference, PLOTSETTINGS
group 74). That means nothing for model space: opened in AutoCAD 2027, a
drawing saved by CADCraft had a blank "What to plot", no preview and no scale
in the Plot dialog for Model. Model space now gets what PLOT does for it: the
drawing extents scaled to fit (74 = 1, 75 = 0). DWG saves go through the same
writer; the reader already ignores the Model layout's plot settings.
