The following pre-packaged resource, derived from this base command, is available:

Applied Parameters: None


This command is used to export the layers of the current document in Gerber format.


This command can be accessed from the CAMtastic Editor by:

  • Choosing the File » Export » Gerber command from the main menus.
  • Clicking the  button, on the Import/Export Tools drop-down () of the Utilities toolbar.


After launching the command, the Export Gerber(s) dialog will appear. Use this dialog to define various export options, including whether to use Step & Repeat Codes, whether to separate and export composite layers as individual files, and also to define the Gerber format.

By default, the exported Gerber format will initially be set to RS-274-X. By pressing the RS-274-X button repeatedly, you can cycle through the available Gerber formats: RS-274, RS-274-X, or Fire9000.

Press the Settings button to open the Gerber Export Settings dialog, from where you can define the numerical formatting for the exported files.

After defining the export options as required, click on the OK button - the Write Gerber(s) dialog appears. Use this dialog to define which files are to be exported and where they are to be stored. By default, all Gerber files are selected for export. Each file can be renamed by clicking within the name field. The associated file extension can also be changed to another if required, by again clicking directly within the name field or, alternatively, right-clicking on the entry and choosing File Extensions from the context menu. The new extension required can be typed into the subsequent Enter Value dialog that appears.

With name(s), extension(s), and storage location defined as required, click OK to generate the file(s).


  1. Gerber format RS-274 files require a separate aperture file, while extended formats RS-274-X and Fire9000 do not (as all apertures are embedded inside the Gerber files).
  2. If saving a file with the same name and in the same location as an existing file, the existing file will be overwritten without warning.
