The Image displays an example, in which line objects are exported in CAD blocks with attributes.

What is important is that in DxfEntity the Inserttype and a header file is used. The result of CAD export of lines is not comparable with the previous examples. Starting from lines, a new block is created for each feature during export. The attributes are attributed to the created blocks but not displayed.

The lines can later be changed geometrically again in AutoCAD only if the block is broken up. But then the attributes are lost again.
