I think this question must have been asked a thousand times before, but after several attempts to find a solution i am sorry to ask it again: I would like to "delete faces with only one edge connected to another face". Remaining edges and vertices not connected to another face should also be removed.
I can probably rephrase the task to "delete vertices with only two edges connected". I guess that is more or less the same.
I assume there is a simple sequence of commands to achieve that, but I am simply too blind to find it.
I am aware that after a first iteration in the example above, deleting the face on the right side will result in another face that has only one connected edge. This can be covered in a next iteration, no worries.
