Saving to DXF and reopening lost several table and object-section items.
They are now written and read as the DXF Reference describes:
- LTYPE: embedded text and shape elements (74 type flags, 75 shape number,
340 STYLE, 46 scale, 50 rotation, 44/45 offset, 9 text). Shapes from a
shape file get an unnamed shape STYLE record (70 bit 1). DashElement
gains an `absolute` flag for absolute rotations (74 bit 1). The built-in
FENCELINE1 names its text style (Standard).
- MLEADERSTYLE objects in ACAD_MLEADERSTYLE with arrow size, text height,
landing gap, dogleg length and text style, plus $CMLEADERSTYLE, so the
current multileader style survives reopening.
- LAYOUT plot settings: device (2), plot style table (7), plot area (74),
custom scale (142/143, 147), scale to fit (70 bit 16 with 75 = 0),
centred plot and lineweights (70 bits 4 and 128). The layout's saved
paper-space view goes in CADCraft xdata on the LAYOUT object.
- VIEW and UCS table records, and GROUP objects in ACAD_GROUP (members
that were written to the file). A named view's layer state is CADCraft
xdata on the VIEW record.
