This is one of those things I have wondered about for a long time but never asked about. What is the difference between and Auto handle and an Aligned handle on a curve. The both look like they do the same thing. I know that vector handles point to the previous and next handles, I know that Free handles allow you to shape each side of the curve on the handle’s side of the control point/vertex independantly. But the other two I have know idea what they do or MOST importantly what is the difference between them.
Auto handles are automaticly calculated by Blender, you can’t reshape a curve defined by autohandles (other than by moving the Control Vertice).
Aligned Handles can be moved freely by the user, but it will always keep both ends of the handles in line.
