Software Companions GerbView 7.55 (x86/x64)

GerbView® is an advanced but easy to use application that enables you to view, print, convert and markup Gerber, HPGL, HPGL/2, Excellon and raster files. GerbView supports both RS274D and RS274X (with embedded aperture information) Gerber formats. You can use GerbView to convert from the old RS274D Gerber standard to the new RS274X with embedded aperture information.
Gerbview will visualize your design, on the screen or in hardcopy. No more waiting for photoplots or your prototype circuit board, to see your true design.
In GerbView you work with a workspace that can contain one or more files of the supported file formats. The workspace can be saved for later use. The saved workspace will link to your design files, so only need to reload the workspace file to see the whole design.
Markup elements like text, arrows, lines, images, ellipses and polygons can also be added to the workspace. Markups will be stored in a separate file.
GerbView can convert Gerber, HPGL, HPGL/2 and Excellon files to AutoDesk DXF, AutoDesk DWF, Adobe PDF and other formats. See full list of supported formats below.
GerbView can rasterize single files, or whole workspaces, and save to one of the supported raster formats. Markup elements can optionally be included in the conversion.
GerbView has mouse-controlled zoom in, zoom out, zoom area and panning.
You can print scaled or in real size. All Windows based plotters and printers are supported. Poster mode, also known as tiled pages, can be used to print large designs and drawings on e.g. several A4/Letter pages.
Use measure and query tools to get information about apertures, tools, pens, distances and areas.
