**Curve Rebuild**

* **Spans:** Number of spans to rebuild the curve with. The default degree is 3. Using a spans of 5 will result in a curve with 8 CVs (3 degree + 5 spans)

**Clump Ramp/Repel**

* Choose whether to **clump** or **repel** curves.

**Ramp Control**

* **Reference:**&#x20;
  * **Center** - Uses the center of all selected curves as snapping target
  * **Last Curve** - Uses the last curve selected as snapping target
  * **Auto Rebuild/Match CVs** - Automatically rebuilds the selected curves so they have matching CV count before each clumping operation. If not on, please make sure the curves have same amount of CVs by using the Rebuild Button.

**Clump Mode**

* We can utilize the clump mode to snap more complicated curves as well

**Repel Mode**

* **Strength -** multiplier to the repel ramp. Default is 1, if you wish to repel the curves further away, increase this value.
