DXF Export Options

1 DXF unit

The unit (or scaling factor) specifies the physical unit of one DXF unit.
DXF files are unitless — a distance of e.g. 10 units may correspond to 10 microns, 10 inches, or even 10 meters. It is therefore very important that you specify the meaning of the DXF units. Select microns if you want a distance of 1 to represent 1 micron in the DXF file. This does not limit your drawing's resolution to one micron because DXF supports fractional units.

Scale drawing

This field allows the user to scale the imported drawing by any value. This can also be used to 'size' a design.

Round (Precision)

DXF polylines have square line ends. If the imported file contains round wire ends, choose Round to draw rounded line ends as a series of SOLID triangles. Use Precision to control the precision of this approximated circle.

Square extended

Round line ends are converted to square, half-width extended ends.

Flat

Round line ends are removed.

Explode text into polygons

By default, text entities are exported as TEXT / MTEXT. Check this option if you prefer text to be written using polygon outlines.

DXF Version

Specify if you want to generate a DXF Release 12 (and later), DXF Release 14 (and later) or DXF 2000 (and later) compatible DXF file. DXF Release 12 files can be read by a large number of CAD programs. DXF Release 14 files are less compatible, but tend to be smaller if the file contains a large number of polylines. DXF Release 2000 include all the features of DXF Release 14, but support longer block and layer names with an extended character set.

Binary DXF

If your target application supports it, use binary DXF to further reduce the file size of the generated DXF file.

Export polygons as REGION entities

Check this option to export closed polygons as REGION entities. Holes created through re-entrant polygons are detected and exported as true holes in the created REGION.

Fill zero-width polygons using SOLIDS

Check this option to fill all closed zero-width polygons using triangular SOLIDS. Enabling this option effectively triangulates all polygons and can also be used to unwind self-intersecting polygons.

Flatten file structure

When checked, the entire file hierarchy will be converted to a flattened DXF file, which will not contain any blocks.
