How to delete the overlapped vertices in a 3D model? As you can see the image below, it is a human head model unwrapped in the UV/Image Editor. The selected vertices should be the overlapped vertices but I cannot delete them just by pressing Delete key. I can just delete it in the 3D View. However, it is difficult to select them in the 3D View. So, I want to ask that how to easily delete those overlapped vertices?

Unwrapped 3D Human Head in UV/Image Editor
Solving with &quot;Keep UV and edit mode mesh selection in sync&quot; Option
In the UV Editor window, if you enable the Keep UV and edit mode mesh selection in sync option , then the vertices you select in the UV Editor will also be selected in the 3D edit window.
The location of Keep UV and edit mode mesh selection in sync:


Action Demo
You can then go to the 3D window and delete them.
Don't forget to disable the Keep UV and edit mode mesh selection in sync option afterwards.
