Extruding inwards along edges? I have this shape that I want to extrude into. Here's a picture of the situation:



I want to extrude so that it fills in evenly so I can pull it out, add a mirror mod and have the blade looking all nice, however i cant seem to figure out how to extrude along edge normals. How can I do this?
You are looking for the inset tool. create a face from your edge boundary by selecting all vertices (like in your screenshot) and hit  f. Then hit i and drag with the mouse to create the faces.



Or, if you want to extrude to the normal of the face, use  f, then  e instead.
