Fab3000 reads Gerber data in RS-274D, RS-274X, and Fire 9000 formats. Multiple files are read into multiple layers, allowing simultaneous viewing and editing of the gerber data. The system is fully compatible with polygon fills, composite images, and step and repeat codes.

The easiest way to import Gerber files is to use the AutoLoad Gerber Wizard.  It reads in all the information about your Gerber files automatically, and provides aperture file conversions, etc.

 

documentNote: Fab3000 correctly displays Step & Repeat data. Most other CAM software will Crash, Ignore, or draw imaginary boxes. Fab3000 will create a separate Job for each Step & Repeat block which is then inserted into the parent job; maintaining correct Step & Repeat hierarchy, and improving the ability to edit and modify existing Step & Repeats.

 

Command Sequence

 

1. Select menu: File | Import | Gerber.

 

2. Select the Gerber files you want to import, and press "OK".  The Import Gerber wizard dialog box appears.

 

documentNote: To select more than one gerber file, you may use dynamic selection by holding "Shift" or "Ctrl" keys.

 

3. To modify Gerber Import settings, click button "Format Options...". (For 274D Gerbers Only)

 

documentNote: In most cases, Fab3000 will automatically detect the gerber format settings and aperture lists; do not adjust these settings if you are unsure about your gerber file format.

 

4. Select whether your files are in English or Metric units. (For 274D Gerbers Only)

 

5. Click the OK button.  You are returned to the Import Gerber Wizard dialog box.

 

6. Select the corresponding layer types for each file. (Optional)

 

7. Click "Next" to begin importing gerbers.

 

8. Once Gerber loading is complete, a Status & Import log are available for your review.  If Fab3000 encounters any errors or warnings during import, they will be displayed here.

 

9. Click button "Finish" button to view the imported data.

 

documentNote: If you already had existing data in the current job, any imported layers with the same name will be merged within that job.  It is recommended that you instead create a new job for each new "design" that you import into Fab3000
