Turbo iO expands file interoperability in AutoCAD, replacing the AutoCAD Convert

AutoCAD users will now have an easier time sharing their work. The new Turbo iO plug-in for AutoCAD expands file interoperability in AutoCAD. With it, users can open, edit, and save direct to the TurboCAD Windows TCW file format from the add-ins menu in AutoCAD, as well as a number of other file formats.  
Open and edit 3DV, CGM, DAE, DCD, FCD, GEO, IFC, PLT, STL, TCW, U3D, WRL, and WRZ; and be able to save to 3D PDF, 3DM, 3DS, CGM, DAE, IFC, OBJ, PLT, SKP, STEP, SVG, TCW, U3D, WRL, or WRZ formats.

So you may not need an AutoCAD file converter if you install Turbo iO instead.
