I am learning how to use the Knife tool and it's not working for me. I try to make a straight line by clicking on two points with Left mouse button, but the second time I click it, the line disappears. I am trying to cut a diagonal line in the small box on right.
I tried to attach a Blender Screencast but it doesn't allow me to upload avi files, could you please tell me how to do it?
PS While you are at it, could you please check why my vertex snap (or any snap for that matter) is not working when holding down the Ctrl key? I am following a video tutorial and it's supposed to snap at all the corners, but it's only snapping in one or two places. Thanks
