* AutoCAD interop: justified text, DIMPOST, current dimension style, *D block colours What AutoCAD takes from CADCraft's DWG/DXF as it is: - Justified TEXT/ATTRIB/ATTDEF (#1050): group 10 is now where the baseline starts, from the alignment point and the text's width, not the alignment point itself; AutoCAD drew centred and right-aligned text from DWG starting at its alignment point. A stored point close to CADCraft's own (AutoCAD's, exact for its fonts) is kept. - DIMPOST (#1053) is written even when empty: the DWG bridge defaulted a missing one to "<>", and AutoCAD then dropped the "R" of radius dimensions when it regenerated them. - The current dimension style (#1051): the DXF header now carries its DIM* variables (AutoCAD draws new and updated dimensions from them); the DWG bridge points $DIMSTYLE at the style by name (its handle was renumbered, so the writer fell back to Standard), and reading a DWG gives the current dimension and text styles their names back. - *D blocks (#1052): lines, arrows, extension lines and text take the style's DIMCLRD/DIMCLRE/DIMCLRT instead of ByBlock. #1054 (group 42 of a rotated linear dimension) was already fixed on main by #855; acad_interop.rs keeps it covered.

Already right on main since #855; this guards it. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Justified text made here: Left Middle and Left Bottom write their baseline start too text_insert kept a stored insertion point that was within 0.1 x an estimated width + 0.5 x height of CADCraft's baseline start, taking it for AutoCAD's own. The width was estimated from the alignment point's offset, which for Left Middle is only h/2 (vertical), so a text made here, whose stored point is the alignment point, passed and kept it: AutoCAD drew it half a height high (Left Bottom: a third). Reported with a test by @lee-cyrille-maskell. A stored point equal to the alignment point is now always stale. Otherwise the offset is split along and across the baseline: along it the same slack as before (a tenth of the text's width plus half its height, as fonts and their substitutes differ most in width), across it a fifth of the height. Multiline attribute values keep the distance-only check, since their lines are placed by the embedded MTEXT. On 12 drawings made in AutoCAD (1,055 justified texts) the insertion points written are the same as before.
