Revision History GBR2DXF

This document summarizes enhancements and fixes to gbr2dxf/w . Please consult this page on a regular basis to determine what changes have been made to our programs. This revision history covers:

v6.65a 12-4-2014

New Install

This release is with the latest installer.

Windows 8 support

Added support to Windows 8, 32 and 64 bit.


v6.65 11-9-2010

DXF Layer name

DXF layer names were altered when encountering files with high GBR formats (e.g. 5.5) or multiply defined apertures. The altered names ended up being longer than 32 characters which resulted in a program crash. This problem was fixed by both preserving the layer names entered in the GUI and truncating any layer names exceeding 32 characters.

Gerber Polygon

A bug fix was done for Gerber polygon regions that had arc segments but failed to match first and last point. This was fixed by adding a closing line segment when this condition was encountered.


v6.62 12-29-2009

New GBR2DXF option Locus/Point

A new feature was added in GBR2DXF. The new feature can be set in the Setting menu and it allows the user to create 0 width LINE/ARC entity for Gerber draws and a POINT for a Gerber flash.


v6.41 1-29-2009

Major Update
The new version includes all the latest support for 274x data (in sync with ASM50x version 6.54) as well as support for USB key.


v6.06a 2-23-2005

Flexlm Support
The new version includes all the latest support for 274x data as well as support for Flexlm licensing (Node locked and Floating).


v6.00 10-12-2001

Clipping Windows for Custom Apertures was Deficient
The number of maximum windows allowed for custom apertures was 128. It has now been increased to 10000. The other clipping window maximum has been increased the same for consistency.

Custom Aperture In a SR Layer
The contents of custom apertures were SR'd by X and Y in addition of the SR itself. This has been fixed.

Undefined or Duplicate Block Definition in the DXF Output
Older versions might generate a DXF file with the above error if the Gerber file has custom apertures on layer 1 or above. This has been fixed.

Fixed SR handling Problem
If SR is followed by *, then the M02*command e.g.

%SR*%*
M02*

the translator would crash on this combination. This has been fixed to ignore the second SR in the same layer.

New keying/hostinfo 2.
No demo mode.
New about dialog.

v5.10 08-10-1999

Flashing Custom Aperture
Older versions would not use the users specified flash names for custom aperture. This has been fixed.

DXF Blocks Layer
DXF blocks are now drawn on layer 0 instead of the first inserted layer.

Draws Using Custom Aperture
This version supports draws using custom aperture. Under graphics mode, a flash of the custom aperture is generated at path ends and a path with width the diameter of the custom aperture is drawn. In connectivity mode, just a path with width the diameter of the custom is drawn.

Number of DCodes
This version supports dcodes from D10 to D9999 and a max of 10000 custom apertures.

GBRVU/W version 2.17 is included



v5.04 04-28-1999

RS274X Files in Directory with Spaces
Older versions would not process RS274X files in directory with spaces.

Arcs/Circles Shifted by a Distance of a Radius
Older versions would translate arcs or circles shifted.



v5.03 01-14-1999

R14 G36/G37, POEX/POIN Boundary Hatch Fill
This version added hatch filling for R14 DXF output for gerber G36/G37 and POEX/POIN boundaries. POIN will be scratched out from POEX hatch filled boundaries.



v5.02 12-14-1998

Number of Custom Apertures Limit
Older versions would drop data if there are a lot of custom apertures. This limit has been greatly increased to a total of 4000 dcodes for all custom apertures.

Custom Aperture Macro Names
Older versions would translate custom apertures with same macro names wrongly, i.e. all subsequent apertures with the same name would be translated as the first one.



v5.01 12-07-1998

Multiple RS274X/MDA Files
This version allows users to select multiple RS274X or MDA files per translation. Requested by David Brink from EMC.

Circle Output
Added control to output DXF circle or polyline to represent circles. Access this from the Configuration dialog box, Circle control. Requested by Mark Allen.



v5.00 10-30-1998

Auto Detection of 274X, 274D and MDA Autoplot
This version allows users to select any gerber file(s) and it will automatically detect which format they are in. Users do not need to specify the format ahead.

Auto detection also applies to aperture file. Though, if aperture file is not in Artwork format, users need to run the aperture file through the built in Aperture Generator to generate an Artwork format aperture file for use by Gbr2dxf.

Fixed: Limitations on Gerber File Names....
Previous versions of gbr2dxf limited input file names:

  • Only file names in 8.3 format is allowed.
  • Gerber file must have an extension.
  • Names without directory cannot exceed a length of 16.

All such restrictions have been lifted.

New Feature: User configurable Gerber names....
This version allows users to control the file extensions they usually use. Instead of always fixed to .gbr. Access this function via File| Preferences | File Extensions.

For example you can associate the ending .pho with RS274X or .art or .gbr or .ger so that these types of files show up in the file selection box.

Check for Legal DXF Layer Name
This version checks for DXF layer name to make sure it does not have spaces in it. Default is to replace all spaces to underscores '_'. AutoCAD cannot load a file with spaces in it.

Added Working Directory Browse Button
This version has a working directory browse button. Users do not need to type in the full path to the working directory any more, they can browse for it.

Blocks from Flashes Improved
When flashing dcode, older versions would generate a block per dcode per layer. This version generates only 1 block per dcode for all layers. Custom apertures are translated as before, 1 per dcode per layer.
