Great and very powerful function for exporting shapes to DXF format - it creates very smooth arcs and polylines
New and quite powerful function. Allows you to export the objects using a different set of commands, such as a standard set of DXF (R11, R12) and classic HPGL (adding arcs - AR).
Some words about main parameters:
Commands - set of commands in which to export objects (DXF or HPGL).
Align - allows you to shift the starting point coordinates in the exported file in relation to the lower left corner of the selected objects.
Lines+ARCs / Lines only - use to export shapes with ARCs or only polylines.
ARC fitting tolerance - as is.
LINE fitting tolerance - as is.
Show simulation (Unavailable now) - show result after processing.
Export units - MM and Inches are available.
