ViewCompanion Standard

is a powerful application for viewing, printing and converting plotter files generated by your CAD program or plotter driver. ViewCompanion can open PLT plotter files using HPGL, HP-GL/2, KIPGL, HP-RTL and Calcomp formats.
In addition to plotter files ViewCompanion can view, print and convert Adobe PDF, CGM, Autodesk DWF and Gerber files. 
One of the most important features in ViewCompanion is the ability to convert the viewed file into another format and ViewCompanion can convert to the following file formats:

Adobe PDF Adobe PDF/A Adobe Postscript® Autodesk DWF Autodesk DXF CALS Group 4 Raster Computer Graphics Metafile Gerber RS-274X GIF Image

HPGL/2 JPEG Image Paintbrush PCX Portable Network Graphics (PNG) Scalable Vector Graphics (SVG) TIFF Raster WebP Image Windows Bitmap (BMP) Windows Metafile (EMF & WMF)

Adobe PDF, Autodesk Drawing Web Format (DWF) and Scalable Vector Graphics (SVG) are all very useful and popular formats for distributing drawings on the Internet.
ViewCompanion can convert your PLT, Gerber, CGM and DWF files to Autodesk DXF format which you can read in any major CAD application.

You may measure distances and areas using ViewCompanion's precise measurement tools with snap to drawing geometry. If your drawings are not in original scale (1:1) you may calibrate the measurement tools to provide correct results.

Use ViewCompanion to annotate your file with markup elements like rectangles, lines, dimension lines, area measurements, text, polygons, text, arrows, symbols, stamps, images and more. All markup elements will be stored in a separate file and the original file will not be modified.
