I have a mesh with a cylindrical extrusion and I would like to make this extrusion appear like a cone or needle. I have tried scaling the end faces/edges/verts of the cylinder, but this scales the entire mesh. I do not want to scale the entire mesh.

Before:

+================+
|                |
|                +=============================+
|                                              |
|                           cylinder           |         
|                                              |
|    (mesh)      +=============================+
|                |
+================+

Desired result:

+================+
|                |
|                +=============+
|                               ========+                
|                   needle/cone          ======             
|                               ========+              
|    (mesh)      +=============+
|                |
+================+

Yes, I'm in Edit Mode and, yes, pivot center is set to Median Point.

Here's a screencast of what is happening.

    $\begingroup$ +1 for the original example images :) You can also take a screenshot or screencast with blender, might be faster.. $\endgroup$ – gandalf3 Nov 2 '13 at 2:52

You are either in Object Mode or have the whole mesh selected.

Make sure that you are in Edit Mode (Tab). In the header of the 3D View:

Edit Mode selection

Then press A repeatedly until nothing is selected. Then use border select (B) for example to select the right most vertices:

Selection

Then scale them down. It might be that you have to change your pivot point to Median Point. Again in the 3D View header:

Median Point selection

You also have to make sure that proportional editing is off (O) (header again).

  • $\begingroup$ Thanks, I gave your recommendations a shot, but still having issues. See the screencast in my updated question. $\endgroup$ – Micah Bolen Oct 31 '13 at 11:49
  • $\begingroup$ I'm selecting the outermost verts and then pressing <kbd>S</kbd> to scale. $\endgroup$ – Micah Bolen Oct 31 '13 at 11:59

    $\begingroup$ I updated my answer. You have proportional editing on. $\endgroup$ – Maccesch Oct 31 '13 at 11:59
  • $\begingroup$ That was it. Proportional editing was the problem. $\endgroup$ – Micah Bolen Oct 31 '13 at 12:03

Another alternative is to, when the points at the right are selected, press Alt-M to merge the points together.

  • $\begingroup$ @WChargin I didn't downvote this, but It doesn't answer the question "How to scale down only part of a mesh". $\endgroup$ – gandalf3 Nov 8 '13 at 19:23

    $\begingroup$ The question is how to turn it into a cone shaped structure. merging the vertices does that. $\endgroup$ – Joel Boulet Nov 8 '13 at 21:02
