Does CADtools support DXF, DWG, or other CAD-related formats?
CADtools does not add any new file import/export features to Adobe Illustrator, but DXF import/export is fully supported in Illustrator since CS3. Once a file is imported as vector artwork inside Adobe Illustrator, CADtools can be used to dimension or edit the artwork. In some cases, an imported file may contain artwork comprised of small line segments. Dimensioning tools by line, as well as radius, diameter, arc length, and Bezier curvature dimensioning tools will not work for such segmented artwork. To connect these DXF/DWG line segments, use the Concatenate filter available at Graffix Software. For more information on opening or placing files within Illustrator, please refer to the Adobe Illustrator User Guide, technical notes, and the Adobe web site.
