# InsertEdge (loop)
## 
InsertEdge (loop)
The InsertEdge command inserts edges beside an edge loop (left) or across an edge ring (right) on a SubD or mesh.
* When edges fail to insert, the defective geometry is marked with a text dot. The [secondary text](https://docs.mcneel.com/rhino/8/help/en-us/commands/dot.htm#Secondary_text) in the text dot properties gives a hint of what should be repaired.
### **Type**
**Loop:** Insert edges beside the selected edge loop.
* **BothSides:** Insert edges on both sides of the selected edge loop.
**Ring:** Insert edges across the selected edge ring.
### **Mode**
**Full:** Select an entire edge loop (left) or ring (right) based on the Type option to insert edges.
**Range:** Select the start and end edges in a range of loop (left) or ring (right) based on the Type option to insert edges.
### **OffsetMode**
**Proportional:** The amount is proportional to each crossing edge length. The input number should be between 0 and 1.0.
**Absolute:** The amount is same for all edges. The input number is a distance in the model unit.
