The Insert AutoCAD Drawing add-on inserts a .dwg or .dxf file into the active page in an existing Visio document as a read-only ActiveX object. The active Visio application window must contain a document drawing page when this add-on is run (otherwise an error is generated).
Because of this, correct imports of DXF files have been difficult. Autodesk now publishes the DXF specifications as a PDF on its website. Versions of AutoCAD from Release 10 (October 1988) and up support both ASCII and binary forms of DXF. Earlier versions support only ASCII.
