XGBRVU enables designers to graphically display any Gerber photoplotter file in true WYSIWYG fashion on your workstation screen. Once loaded, the data is available for viewing, verifying, and measuring. Data cannot be modified in any way. Data can be plotted to a variety of plotters: lasers, Postscript printers and inkjets.

Upon starting GBRVU you will be prompted for the type of Gerber file to load. In order to avoid manual entry of aperture definitions for 274D files, we've written aperture translators for several popular applications. By identifying the source of Gerber file the appropriate translations activated.

Layer Display

GBRVU's layer menu enables the designer to load up to 128 Gerber files quickly. Layers can be individually turned on or off. Each layer's display mode can be set to: Paint, dark data or clear background; Negative, clear data on a dark background; or Scratch, data subjects from previous layers. Each layer can be assigned a color and fill pattern.

Easy Aperture Menu & Setup

If apertures must be entered the user can do so via an easy-to-use spreadsheet dialog. You can see at a glance which apertures are used.

Polygons & Composite Layers

XGBRVU supports both 274X area fill (G36/37) and the MDA's POEX/POIN polygon commands. It also supports 274X Dark and Clear layers (LPD/LPC) and MDA's linked files.

Printing and Plotting

Designers often need to make checkplots directly from Gerber data generated by their board design software. Such a checkplot more accurately reflects the final phototool than plots made directly from within the application.

XGBRVU supports both the FIRE 9000 Autoplot header with embedded apertures and Gerber's RS274X format including custom apertures, polygons and merged dark and clear layers.

XGBRVU's rasterizers are extremely fast! - by sending a native raster to a plotter instead of HPGL or Postscript, you can get large format plots out for an entire workgroup.

Supported Plot/Print formats:

  • PCL for HP and compatible laser printers (user settable resolution and page size)

  • RTL for HP and compatible color inkjet plotters and printers

  • Postscript II - for any level II compatible Postscript printer - BW or Color

  • TIFF - for dropping into Framemaker, Photoshop and other DTP applications



Batch Plotting

XGBRVU can generate plots directly using the command line . Those interested in batch plotting for an entire workgroup should refer to our GBRPLOT program. GBRPLOT can be used with a shell wrapper or as an input filter for a printer queue - just lp your Gerber data like it was a print file.
