ViewCompanion Premium® is the most powerful member of the ViewCompanion family. ViewCompanion Premium can view, print and convert PLT plot files, Adobe PDF, Autodesk DWF, Postscript, CGM, TIFF, CALS and many other formats. ViewCompanion Premium support PLT plotter files using HPGL, HPGL/2, HP-RTL and Calcomp formats.
If you need to distribute drawings, e.g. on the Internet, you can convert your drawings to Autodesk Drawing Web Format (DWF), Scalable Vector Graphics (SVG) or Adobe PDF. All these formats are very popular for distributing drawings.
You can convert multiple files of different formats to a single multi-page PDF, DWF or TIFF file.
ViewCompanion can split a multi-page PDF, PDF or DWF files into several single paged files.
Your PLT, PDF, CGM and DWF files can be converted to Autodesk DXF format, which can be read by almost all CAD application, e.g.: Autodesk AutoCAD and Microstation.
Both batch conversion and printing is included. The software can be configured to monitor a user selected folder, and all files copied to that folder will be automatically printed.
ViewCompanion gives you advanced functions for zooming and panning, and you can view your files fast and accurate.
Use Viewcompanion's precise tools to measure dimension lengths and areas. You can measure using snap to drawing geometry for highest accuracy. Calibration of the measurement tools is available to make sure you get correct results if your drawings are not 1:1. The measurement results may be exported to csv, which can be loaded into Excel or any other spreadsheet application.
With ViewCompanion Premium you can add markups to the loaded file. Supported markup elements include rectangles, lines, dimension lines, area measurements, ellipses, polygons, text, arrows, stamps and images.
You can select one of the predefined stamps or create your own. User defined symbol libraries makes it easy to add frequently used symbols as markups. Hyperlinks can be added to markup elements, and a hyperlink can either open another drawing inside ViewCompanion, or open an Internet location (URL) using the default browser.
All markup elements are stored in a separate file and the original file will be left unmodified.
The markup elements can optionally be included when the viewed file is printed or converted.
You can export markup elements as Autodesk DXF, Autodesk DWF, CGM and other formats.
