# SubDExpandEdges
## 
SubDExpandEdges
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](https://docs.mcneel.com/rhino/8/help/en-us/commands/subddisplaytoggle.htm).
* **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.
