ConvertCAD 1.2.0

Added

• Radius, diameter, angle and arc length dimensions. An arrow touching a circle or an
  arc along its radius with an "R…" / "Ø…" value becomes a true RADIUS or DIAMETER
  dimension (value inside or outside, with its landing). Two arrows on an arc pointing
  along it become an ANGULAR dimension when the value ("45°", "30°15'") agrees with the
  drawn arc, or an ARC LENGTH dimension when the value is written with "⌒" or matches the
  arc length at the sheet scale. Values that disagree with the drawing are not rebuilt
  (they stay on DIM_RAW). ARC_DIMENSION is written from DXF 2007; for older versions and
  DWG the arc length dimension is kept as its drawing on layer DIM.
• Texture hatches: sand, concrete, gravel, earth, brick, insulation and dotted areas,
  which plotters explode into thousands of dashes and dots, become one HATCH with the
  standard AutoCAD pattern (AR-SAND, AR-CONC, GRAVEL, EARTH, BRICK, AR-B816, AR-BRSTD,
  INSUL, DOTS) at the scale, angle and origin measured on the PDF, inside the drawn
  boundary. A pattern is kept only when, drawn again, it reproduces the PDF pieces; sand
  and concrete, which look random, are accepted on their statistics and the report says
  their scale and position are estimated. Anything else stays as lines.
• Repeated symbols at any angle (a valve turned 30°…) become one block, with the
  measured rotation (and mirroring).
• Arcs on scanned drawings: curved strokes are traced as ARC entities (door swings,
  fillets, curved walls) instead of chains of short lines.
• Selection in the result preview (read-only): click an entity to highlight it; the
  status bar shows its type, layer and size, and its layer is selected in Layers.
• Interface in Spanish, German and Arabic (View → Language), with the user guide, the
  OCR guide and the terms of use; Arabic is written right to left (the drawings are not
  mirrored). Translations not yet reviewed by native speakers. Windows installer wizard in
  Spanish, German and Arabic too.
• Optional update check (Help → Check for updates…, Check for updates at startup,
  off by default): one request to GitHub for the latest version number; nothing is sent,
  nothing is installed.

Changed

• Toolbar tools show their icon only when their labels do not fit the window (longer
  German and Spanish labels); the name stays in the tooltip.
• DWG: 3-point angular dimensions are adapted for LibreDWG (it refused the whole drawing).
