To bring Gerber files into design software like Fusion 360, you typically use an import function, often facilitated by a User Language Program (ULP). This process allows you to view or potentially reverse-engineer the board layout represented by the Gerber data.
Here is a step-by-step guide based on the provided reference for importing Gerber files using the import-gerber ULP in Fusion 360:
Steps to Import Gerber Files
The process involves preparing a new board design in your software and then running a specific import utility.
-
Create a New Board:
- Begin by creating a brand new board design file within your CAD software. This will be the canvas onto which the Gerber data is imported.
-
Run ULP:
- Navigate to the Automation tab in Fusion 360.
- Look for the Run ULP option and click it. This opens a dialog box where you can select and run User Language Programs.
-
Search for "import-gerber":
- In the ULP popup window that appears, use the search bar to find the "import-gerber" ULP. Select it once it appears in the results.
-
Select Gerber Files:
- A new window specific to the "import-gerber" ULP will open.
- Use the Select option within this window to browse your computer and locate the Gerber files (.gbr or similar extensions) you wish to import. You may need to select multiple files representing different layers (e.g., top copper, bottom copper, soldermask, silkscreen, drill file).
-
Import Files:
- Once the files are selected and loaded into the ULP window, find and select the Import option.
- The ULP will then process the selected Gerber files and convert them into graphical objects within your new board design.
Following these steps will bring the layout defined by the Gerber files into your active board design session in Fusion 360.
What are Gerber Files?
Gerber files are a standard format used by PCB (Printed Circuit Board) manufacturing industries. They contain all the necessary information about the board design layers, drill holes, and other features required to manufacture the physical board. They are essentially the "blueprint" for fabrication.
Importing them back into design software can be useful for:
- Verifying manufacturer-provided Gerbers.
- Examining or reverse-engineering existing board layouts (with caution regarding intellectual property).
- Comparing design revisions.
This method focuses on the import process within design software, distinct from "uploading" Gerbers to a PCB manufacturer's website for fabrication quotes and orders.
