# Constraint List

The Constraint List provides a global view of all constraints within a registration Bundle. It allows users to inspect, sort, enable or disable, and optimise constraints with precision, improving control over registration quality and troubleshooting.

## **Core Functionality**

The Constraints List is available on the **Properties** panel of the selected Bundle.

When the **Constraint List** button is clicked, the list opens, displaying all constraints (targets and Cloud-to-Cloud) for the selected Bundle.

The list can be sorted by:

- Setup
- Link ID
- Target label
- Error values
- Constraint type

Each constraint entry includes:

- Type (target or Cloud-to-Cloud)
- Setup pair
- Lock status
- Enabled/disabled status
- Overlap status
- Weight
- Various error metrics
- Link colour

## **Interactive Features**

### **Enable/Disable Constraints**

Users can selectively disable constraints to test their impact. If all constraints in a Link are disabled, the Link is removed from the Bundle.

To restore the removed Link, use the **Undo** button.

### **Auto-Update vs. Manual Apply**

- **Auto-Update**: Selecting the checkbox enables automatic reoptimization of the Bundle after each change.
- **Apply**: Clicking the button allows applying multiple changes before reoptimising the Bundle.

### **Versioning**

The **Make Version** button lets users save the current version of the list in the project’s Version Manager before editing constraints, thereby preserving a restore point.

It is highly recommended to create a version:

- When first using the Constraint List.
- Before disabling multiple constraints or Links.

### Disabling Links

Disabling Links helps users identify connected Setups and evaluate how constraints affect alignment.

To disable Links, select the necessary ones in the Constraint List and then select **Disable** from the context menu. The Link will be removed. However, it's also removed from the Constraint List.

To get the deleted Link back, use the **Undo** feature.

## **Differences from Cyclone Core**

| Feature | Cyclone REGISTER 360 PLUS | Cyclone Core |
| --- | --- | --- |
| Constraint visibility | Global list per Bundle | Global list per Setup |
| Error column | Shows alignment error | Mix of Global (for Cloud-to-Cloud links) & Slope error (for Target links) |
| Global Error | ✅ Available | ❌ Not available |
| Pre-optimized error | ✅ Available | ❌ Not available |
| Link persistence | Removed if all constraints are disabled | Link remains |
| Group support | ❌ Not supported | ✅ Supported |
| Multi-Bundle editing | ❌ One Bundle at a time | ✅ Possible |

## Useful Tips

- Do not disable all constraints in a Link unless they should be removed.
- Breaking Bundles by removing critical Links is not allowed.
- Always make a version before major edits.
