scViewerX is a feature-rich ActiveX control that can view, compare, print and convert PLT, Adobe PDF, Autodesk DWF, CGM, Gerber, TIFF, CALS and other formats. ScViewerX has markup functionality (also known as annotation or commenting) that can be used to add stamps, texts, measurements, barcodes, images and much more to the viewed document. The annotation measurement tools can be used to do digital takeoff. A scViewerX SDK developer license will allow you can create an application that can view, compare annotate, print and convert files using the control. scViewerX can convert your files to many different file formats, including Adobe PDF, Adobe PDF/A, Autodesk DWF, AutoCAD DXF, CGM, CALS, JPEG, TIFF and more.
