Resumo Executivo

  • LibreCAD is a free, GPL-licensed 2D CAD application.
  • It reads and writes DXF and DWG files, supports layers, blocks, dimensions, hatching, and most of the things you’d expect from a 2D CAD tool.
  • It’s built in C++ on top of Qt and has been around since the QCad days.
  • The first 90% was mechanical: get the toolchain up, compile, boot the GUI, wire up files.
  • The last 10% — making modal dialogs actually work — is where the interesting problems were, and it’s what forced a rebuild of the whole toolchain.
