1. Setting Trace Width
Here’s exactly how to change the width of a selected trace:
Here’s exactly how to change the width of a selected trace:
- In the right-hand panel, navigate to “Object Specific Rules.”
- Select the Edit button and then Add.
- Search for
Trace Widthin the rule selector and select Add.- In the property’s field, enter 3 mm.

2. Creating a Keep-Out Zone
Use a Keep Out rule to push copper (or other objects) away from your antenna trace by 2 mm:
Use a Keep Out rule to push copper (or other objects) away from your antenna trace by 2 mm:
Keep Out Rule
- Select the object to create a copper fill around (such as an antenna trace).
- Navigate to the Object-specific rules on the right and click Edit → Add.
- Find and add the Keep Out rule.
- Enter 2 mm as the keep-out distance.
- Flux will regenerate copper fills (and prevent other objects) within that zone.

3. Enforcing Trace Length
I couldn’t find documentation on scoping or enforcing a specific trace length (e.g., 28 mm) as a layout rule. Flux currently does not expose a “length constraint” rule—you’ll need to manually route the antenna trace to that length and verify it using the measure tool.
