PLT files or AutoCAD Plotter Documents can be printed with the help of a plotter. These files are based on the HPGL format and can only be opened with Autodesk AutoCAD 2013 and ArtCutS. However, you can view PLT files with virtually any photo viewers if you convert PLT files to TIFF format. The fastest way to convert PLT to TIFF is to use a specialized CAD converter. CoolUtils presents Total CAD Converter - a unique batch PLT converter designed to process files to TIFF and many other formats. Supported output formats include PDF, JPEG, TIFF, JPEG, WMF, BMP, WMF, DXF, PNG, DXF, CGM, BMP, HPGL, CGM, HPGL, and SVG. The list of supported input formats is even longer: DWG, DXF, PLT, DWF, PLT, HG, HPG, HGL, PLO, HPL, HPGL, HP, HP1, HP2, HPGL2, HP1, HPGL2, HP2, SPL, GL2, PRN, SVG, SPL, and CGM.
