Lets you edit creases in your subdivision objects including creases that were created in other applications such as Autodesk Maya or Autodesk Fusion 360.
Use this tool to create transitions between creased and non-creased areas of an edge, adjust the sharpness of the crease, and offset the position the crease.
Access the tool from the Subdivision Palette:
Subdiv Modify Crease settings
Selecting a creased edge displays an in-canvas manipulator, which allows you to select a transition Length value. You can choose a transition Length between 3 and 6 edges. The greater the transition Length, the smoother the transition. The default value is 3.
For best results, your creased edge should consist of at least four edges from its end point to the start of the transition. You cannot add a transition to a crease that only consists of two edges.

Adjusts the amount of creasing to make the crease softer or harder than the default crease. By default, creases have a Sharpness of 1, which generates a G0 crease. Reducing this value softens the crease to a point where 0 removes it. Values greater than 1 increase the sharpness to create exaggerated creases. A value of 2 makes the crease twice as sharp as a default crease.
Offsets the highest point of the crease to either side the edge center point. Use this option to change the shape of the crease.
Modify crease workflows
Select the tool.
Select the crease fade you want to modify.
The crease is now highlighted in green, and a default crease transition is applied to the selected crease. When you deselect the creased edge, it displays as a dashed line, which indicates that it has been modified. The surrounding topology wireframe displays green, indicatiing that it now has construction history.
To choose another transition Length, in the viewport, do any of the following:
RMB-click under Length and select a value from the list.
LMB-click under Length to cycle through the Length values.
Click a point along the edge where you want the crease transition to end.
In the viewport, right-click under Length and select Off or click the first edge in the transition. When you turn off a crease transition, the subdivision control cage is not modified. Only the underlying surface is modified, which has history and can be query edited and turned on again.
There are some scenarios when the Sharpness and Bias parameters cannot be modified. These include the following:

About modifying creases
Before modifying creased edges, note the following:
After selecting a creased edge, Alias displays areas in red when the subdivision topology does not support a crease fade. This can happen in the following situations:
