Blender - Proportional Editing > Project 2d

[Dree Eames]

A new addition to the proportional editing tools in Blender has appeared in both the 3d edit and UV edit windows.  I kinda sorta understand what it's doing...well maybe not.  But what I'm really curious about is why.  What does it do?  When might one use it? It must be worth adding to the mix, but I can only find 2 videos on youtube and they are in Spanish, which unfortunately I don't speak.  And I can't figure out the Blender wiki illustration.

Can anyone enlighten me here?

I use proportional editing when I need to move move a vertex and keep a smooth surface. Like for moving a skirt out a bit to reduce the avatar poke through.

The idea is you can select a vertex or group of vertices and move them. The prportional adjustment moves the vertices near by almost as much and those further away less.

You can adjust the area being affected and how strong the 'magitizum' is that pulls the nearby vertices along.

Google returns 52K+ hits on the feature. Look outside YouTube. Inside YouTube I find 1200+ hits.

Thanks for responding Nalates.  I do understand what proportional editing is, however your information will be useful to newcomers to Blender.  I use proportional editing all the time as it's quite similar to using the sculpt mode except you can see the cage and gauge how your actions are effecting the topology of your model.

My specific question pertains to the new tool added which is "Project 2D".

Do you have any specific knowledge that pertains to this added feature?
