For those who do not know this

I was just playing around with Bmesh and the knife tool.

If you are using Bmesh version of blender and if you want to make a straight cut with the knife tool:

Press K to activate knife

Click where you want to start the cut

Press C and make the cut

Right click to finish cutting

If you want to cut something in the middle, activate knife tool and hold down CTRL. The knife cursor will snap to the center of an edge. Even if there is no vertex there.

Thank you! I was wondering about how to do this with Bmesh. I was thinking we were going to lose a few features for awhile.
