Certain object types, including ACIS solids and regions, are not documented. For example, each place always has a longitude and a latitude.Īs AutoCAD has become more powerful, supporting more complex object types, DXF has become less useful. The KML file specifies a set of features (placemarks, images, polygons, 3D models, textual descriptions, etc.) displayed on maps in geospatial software implementing the KML encoding. Versions of AutoCAD from Release 10 and up support both ASCII and binary forms of DXF. AutoCAD DXF (Drawing Interchange Format, or Drawing Exchange Format) is a CAD data file format developed by Autodesk for enabling data interoperability between AutoCAD and other programs.
