Filters for Point Movement
Set a point move filter to control how the selected points move when you modify the active point. In the following cases, the first point on the right is dragged upward.
• ![](../../surfacing/style/images/ff_constant.png)
Constant—The selected points move an equal amount.
• ![](../../surfacing/style/images/ff_linear.png)
Linear—The selected points drop off linearly in relation to the distance from the dragged point.
• ![](../../surfacing/style/images/ff_smooth.png)
Smooth—The selected points drop off quadratically in relation to the distance from the dragged point.
