Object Edit > Smooth

Improves the smoothness of surfaces and curves by harmonizing CV distances and simultaneously minimizing angles/kinks inside the hulls.

Procedures

Smooth Options

Smoothing Factor: Controls the effect of each smoothing step. The smaller the smoothing factor, the smaller the movements of the CVs.
Undo: Interpolates between the current result and the original input. A value of 1 shows the final result of all smoothing operations so far, 0 represents the original input. If Check Deviation is turned on, the deviation updates dynamically.
Fixed Edges: Keeps the edges of the surface fixed so the edge CVs do not move during the smoothing operation.
Check Deviation: Displays and updates the maximum deviation between the input and smoothed object after each Smooth.
Proxy Display: Displays the original input.
