@Robert Feranec I am learning Advance Design in Fedevel Academy, I was wondering how did you disable all nets and made them gray except the one which you selected.
I have tried shift + S or PCB filter but they weren't successful.

🤖 In the meantime, here’s a response from the [FEDEVEL AI HW Assistant]().
It helps to find relevant resources for your question, but it may make mistakes as it’s still in early development.

This is the response from the AI Assistant:
To highlight a single net while dimming others in Altium Designer, follow these steps:

1. **Use the PCB Panel** (source 2, 8):
- Open the PCB panel (Panels > PCB)
- Select "Nets" view from the dropdown
- Click the "Clear" button first to remove any existing filters

2. **Highlight the desired net** (source 14, 15):
- In the nets list, select your target net
- Right-click and choose "Highlight"
- Enable the "Dimming" checkbox in the panel (looks like a sun icon)

3. **Adjust dimming intensity**:
- Use square brackets [ ] to control dimming level
- F5 toggles color visibility if needed

Key points from the videos:
- Masking/dimming helps focus on specific nets while keeping others visible but less prominent (source 2)
- Always clear previous filters before applying new ones (source 8)
- Use PCB panel's net highlighting instead of manual selection (source 15)

If this doesn't work:
1. Check your filter settings (Properties panel > "All Objects" enabled)
2. Verify no manual masks are active (source 2)
3. Ensure you're not in single-layer mode (Shift+S cycles through view modes)
