The SubDExpandEdges command expands selected SubD edges into faces.
                                                 
                                            
Command-line options
Offset
The offset settings determine the width of the inserted quad faces. The width is the proportional amount of the crossing edge length in the flat SubD.
Small / Medium / Large
Slides each vertex along the crossing edge with a proportional amount of 0.125 (small), 0.25 (Medium), or 0.5 (Large).
                                                     
                                                
Custom
Allows entering any number between 0.05 and 0.95 for the proportional amount.
Variable
This option is only available when a single edge chain is selected. It allows setting different widths at both ends of the edge chain.
                                                     
                                                
Style
Single
Replaces each input edge with a quad face.
                                                     
                                                
Double
Adds two quad faces adjacent to each input edge.
                                                     
                                                
Ahalf / Bhalf
Adds quad faces on the (A) or (B) side of input edges.
