Sharp Corner 
: Options and Results
Access: Open this function from the following location:
-
Select Faces > Modify Faces > Sharp Corner from the menu bar.

Special Cases
In this function:
-
Lines and Splines are extended linearly.
-
Arcs an Ellipses are extended neutrally.
This means that in certain cases the result is not a sharp corner.

|
If multiple adjacent edges are selected: |
Result: |
|
|
|
Example 2:
|
If one edge is selected: |
The arcs are extended neutrally: |
Result: |
|
|
|
|
Example 3:
|
