View PCB Components and Nets in ODB++ and Gerber X3 Files
GerbView can display component and net information from ODB++ datasets and Gerber X3 files, making it easier to inspect PCB manufacturing data without opening the original PCB CAD system.
Review component placement, designators, pin information, rotations, footprints and electrical net connections together with the visible PCB layers. This helps engineers, PCB manufacturers and reviewers verify board data before fabrication, assembly or documentation.
Component and Net Inspection
- View ODB++ component data
- Inspect Gerber X3 component information
- Review available PCB net connectivity
- Check pins, footprints and rotations
- Export ODB++ component layers to DXF
Why Component and Net Information Matters
Standard Gerber files describe the graphical PCB manufacturing layers, such as copper, solder mask, paste and silkscreen. However, they do not always include higher-level design information such as component names, pins, footprints or electrical nets.
Formats such as ODB++ and Gerber X3 can include this additional information. When this data is available, GerbView lets you inspect it together with the PCB layers, giving you a clearer view of how the board is assembled and connected.
- Checking component placement and orientation
- Reviewing reference designators and footprint information
- Inspecting pin and net data where available
- Verifying PCB manufacturing output before assembly
- Creating documentation for internal review or production
ODB++ Component and Net Support
ODB++ is a manufacturing data format that can contain more than just graphical layer data. Depending on how the dataset was exported, it may include component placement, pins, footprints, net information and other manufacturing details.
GerbView can open ODB++ datasets and display this information in a practical way, allowing you to inspect the board layers and the available component data in the same application.
Component Data
- View component designators
- Inspect component placement
- Check component rotation
- Review footprint and part information
- Inspect available pin data
Net Information
- View available net connectivity
- Trace connections during PCB review
- Use net data together with layer visibility
- Improve manufacturing verification
- Review data without the original CAD system

Gerber X3 Component and Net Data
Gerber X3 extends Gerber-based PCB manufacturing data with additional assembly-related information. When exported by compatible PCB design software, Gerber X3 files may include component and net data in addition to the normal manufacturing layer graphics.
GerbView can use this embedded information to help you inspect components and nets directly together with the Gerber layers.
- View component data in compatible Gerber X3 files
- Inspect available net information
- Navigate PCB layers while reviewing component metadata
- Verify design information during manufacturing review
Gerber X3 files can include additional component and net information when exported by compatible PCB design software.
Inspect PCB Layers Together with Components and Nets
Component and net information is most useful when it can be reviewed together with the actual PCB manufacturing layers. In GerbView, you can control layer visibility, layer colors, layer order and display options while inspecting the available component and connectivity data.
This makes it easier to focus on specific board areas, hide unnecessary layers, measure distances, inspect drill data and compare PCB revisions during the review process.
Layer Review
- Toggle PCB layers on and off
- Change layer colors
- Reorder layers for better inspection
- Use transparency to see overlapping layers
Verification Tools
- Measure distances and areas
- Inspect drill and aperture information
- Compare different PCB revisions
- Create markups and review notes
GerbView can compare Gerber revisions and highlight differences between files.
Export and Documentation Options
GerbView is not limited to viewing PCB data. You can also use it to create documentation and exchange files for other workflows.
ODB++ component layers can be exported to DXF, and PCB data can be printed or converted to supported output formats such as PDF and DXF. Markup tools can be used to add text, barcodes, QR codes, images and review comments.
- Export ODB++ component layers to DXF
- Print PCB layers with optional markup
- Create PDF documentation
- Convert selected PCB data to supported output formats
- Add review notes and visual annotations
Frequently Asked Questions
Can GerbView display component information from ODB++ files?
Yes. GerbView can display component information from ODB++ datasets, including component placement, designators, rotation, pins, footprints and related metadata.
Can GerbView show PCB net connectivity?
Yes. GerbView can display and inspect PCB net connectivity when this information is available in the loaded ODB++ or Gerber X3 file.
Do all Gerber files contain component and net data?
No. Traditional Gerber files mainly describe PCB layer graphics. Component and net information is available only when the file format and export settings include this data, such as with compatible Gerber X3 or ODB++ output.
What is Gerber X3?
Gerber X3 is an extension of the Gerber format that can include assembly-related information, such as component and net data, when exported by compatible PCB design software.
Can GerbView export ODB++ component layers?
Yes. GerbView can export ODB++ component layers to DXF and PDF formats, making them useful for documentation, design review, collaboration, and downstream manufacturing workflows.
