Extrude is not behaving as expected I'm trying to extrude a section, almost like I'm scaling it, but the scaling doesn't seem to be working either. I can't find anything on why this is happening. It was working fine and then halfway through my project it isn't working!



The bottom picture is a screenshot of the tutorial I'm following along with. This is my goal. The top picture is of my project. Extrude pretty much just moves the selection along a dark blue axis. I've tried scaling, even by selecting S > Shift+Z, I've tried every extrude option (region, region normals, and individual faces) and I don't understand!
There are a few ways to shrink/fatten a region of an extrusion.. I don't know if this one is exactly in line with your tutorial....


E Extrude the end of the rod to the desired length of the region to be scaled
Now you have a set of faces whose normals you can extrude along ...  Alt select that face ring
Alt E > (Region, Vertex Normals) extrude the
face selection along its faces' normals.




Now, if you have the Transform Orientation set to 'Normal', you can select the faces at either end of the fattened section, and GZZ to adjust its ends.
