### **Steps**

1. Select a surface.

   The picking location decides the side to create the surface.
2. Select a curve near the surface.

### Options

**Radius**: Move the slider to change the radius, or double-click on the slider to enter a value.

**Range**: Click a number button to change the range of the slider for smaller or larger adjustment.

**Blend Type**

* Arc: Creates a fillet surface with arc sections and tangent (G1) to the input surfaces.

* Deformable: Add more control points to the fillet sections for adjusting tangency and bulge.

* Deformable degree: Sets the degree of fillet sections from 3 to 5.
* Tangent: Moves the second points on both ends in the tangent direction.
* Bulge (For degree 4 and 5): Moves the point(s) in the middle to make the fillet sections sharper or flatter.
* G2 Blend: Creates a blend surface connecting to the input surfaces with curvature (G2) continuity.
