Edge extruding instead of moving the mesh I am trying to transform an edge, but instead it extrudes as a new plane.



This only happens to some edges, and vertices, and I don´t understand why or how to make it move the way I want to. Very new to Blender, and help is appreciated
Hold shift while selecting and then extrude...PS. You need to have at least 1 edge selected for the extrude result not to be a plane!
