I have a mesh and added an edge around it to scale out to give it a little curve on sides(picture1). Normally when you scale the edge around, it scales towards outside equally. But with my mesh, it acts different(picture2). I just wonder if it is normal or something causing it.

Picture1: enter image description here

Picture2: enter image description here

  • $\begingroup$ You should consider Scaling along the geometric surface Normal ... or more casually the Normal. See Shrink Fatten on the Menus. Check the Pivot Center setting on the Edit Mode Menu Area. A suggestion is to resubmit your images so that the Edit Mode Menu Area is visible for readers to see the settings. $\endgroup$ Jul 21, 2017 at 16:26

First, in Object mode, press Ctrl + A and apply rotation and scale. Then use Alt + S instead of just pressing S to scale. This should scale the edge out proportionally.

This demonstrates the difference between S and AltS: enter image description here

  • $\begingroup$ Thank you very much. I always thought S key scaled equally on all directions. I have learned something new with your visual comparison. Thank you very much! :) $\endgroup$

  • $\begingroup$ @Mehmet - You're very welcome. The S key will multiply all selected edges by the scalar value that you input... but the directional part of the edge's vector will remain the same. $\endgroup$
