Help with Align object.

Hello
In 3.0 version,there is a new function,Align poly,where is that and how to use ?ask for more infomation.
Thanks!!!

Do you mean the vertex snapping feature, where a vertex from one mesh can be moved to the same position as a vertex from another mesh? If so, you’ll find the documentation here. If this is not what you want then perhaps you can give some more information about the feature you are looking for.

That’s what i want,Thank you very very much!!
