With "DXF : symboles en blocs" ticked in the export dialog, or --dxf-blocks on the command line, each symbol definition a folio uses is written once as a DXF block and every placed symbol as an INSERT of it. A CAD program then selects, counts and replaces a symbol as one object. The block is drawn by the same code as a symbol drawn in full, as if the symbol sat unturned at the folio's origin, which is DXF (0, sheetHeight): that is the block's base point, so the INSERT carries the symbol's position and quarter-turn and nothing else. Blocks have to come before any entity, so the export collects them first and dxfBegin() writes them in its BLOCKS section. Entities in a block keep their own layers. Off by default; with it off the file is unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
