Hi, I have a project with 5 sch sheets, I was doing the annotation but for some reason the 5th sheet is not annotated. PFA the picture below, I can see the objects in the list and the sheet but it refuses to annotate. All the sheets are located in the same location in the project! (The problem us with sheet 5)

🤖 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:
Based on the video content, here are the key points to check for annotation issues in multi-sheet designs:

1. **Component Locking**: Ensure components in sheet 5 don't have locked designators. In Altium, right-click components > Part Actions > Unlock if needed. Locked designators won't update during annotation.

2. **Annotation Configuration**:
- Use Tools > Annotation > Annotate Schematics
- In "Schematic Annotation Configuration", verify all 5 sheets are selected under "Schematic Sheets To Annotate"
- Check "Order of Processing" matches your hierarchy (left-to-right is common)

3. **Reset Duplicates First**:
- Before annotating, use "Reset Duplicates" (available in annotation dialog)
- This clears all "?" designators and prepares for fresh annotation

4. **Project Hierarchy**:
- Verify sheet 5 is properly added to the project (right-click project > Add Existing to Project)
- Check for broken links - right-click sheet 5 > Properties > Location should match project path

From the video tutorial: [OrCAD Annotation Process](https://www.youtube.com/watch?v=d_TPIxPX01s&t=3567) shows similar annotation workflow principles.

If these don't resolve it:
1. Try annotating just sheet 5 in isolation
2. Check for special characters in sheet filename/path
3. Verify all components in sheet 5 have valid schematic symbols (no missing links to libraries)

As a last resort, reset all designators:
1. Tools > Annotation > Reset Schematic Designators
2. Re-annotate entire project fresh

Let me know if you need clarification on any of these steps.

@FEDEVEL Bot Why do you come with OrCAD answers as both the tag and screenshot show Altium?

Are you able to change things manually in sheet 5?
Is sheet 5 a device sheet?

hmm ... the AI doesnt support file / picture upload 🙁

Just me ranting to the AI.
