Overview

This deserializer converts raw DXF formatted data (files) to JSCAD scripts or geometries. When converting unknown DXF data, converting to JSCAD scripts will provide more information on the converted DXF entities.

DXF Implementation Notes

The DXF(tm) file structure changes continously as AutoDesk releases new features and fixes. So, you can imagine that after 20 years, the contents of DXF files are pretty messed up. Expect the worst.

NOTE: At this time, only ASCII DXF files are supported. BINARY DXF files are not supported.

This deserializer converts only what is supported by JSCAD libraries. Full document conversion is NOT supported, however conversion of the following DXF entities are possible:

DXF Entity JSCAD Geometry Notes
3DFACE to geom3
ARC to path2
CIRCLE to geom2 Start and stop angles are ignored
ELLIPSE to geom2 Start and stop angles are ignored
LINE to path2
LWPOLYLINE to path2 or geom2 Conversion to geom2 if LWPOLYLINE is closed
MESH to geom3
POLYLINE (line) to path2 or geom2 Conversion to geom2 if POLYLINE is closed
POLYLINE (mesh) to geom3
POLYLINE (face) to geom3

In addition, colors are converted using the AutoCad 2017 standard color index (256 colors).

Finally, there are many applications that can save to DXF formats. All testing is performed with files from AutoCad, period.
