I am trying to use the knife tool to create a new topology for a model As you see in the first picture, the knife tool is suppose to create 3 edges and 2 vertexs.
However, in the later picture, you can see that blender only created two edges.
How can I fix this? Even by selecting a turret vertex and trying to join it (J) to the newly created vertex did not work. The only thing that seems to work is selecting the two vertexs and creating a line (F) between them. However, this does not join them or create a face, therefore is useless. Any help would be appreciated.
