SUL to DXF Conversion: FAQ

What are SUL files?

SUL is an old and obsolete image format file associated with GFA RayTrace — a program designed for Atari ST computers. The software was released in the late 1980s and allowed users to operate with 3D objects in an incipient stage, usually implying a lot of time for required calculations. SUL files are now considered rare, so opening them probably requires conversion.

What are DXF files?

DXF (Drawing Exchange Format) is a format associated with AutoCAD, a popular program used for computer-aided design by engineers, architects and other professionals in the field of building design and construction. The DXF format was developed in the early 1980s by Autodesk with the purpose of increasing the interoperability between AutoCAD and other CAD or advanced image design programs. It supports 2-dimensional and 3-dimensional drawings, and can be opened using a wide array of image processing programs.
