First of all, how to do this without any add-on, is it possible? I have a lot of vertices and I would like to align them with one particular vertex but only in X dimension, leaving Y and Z unchanged. So I selected this vertex, snapped cursor to it and then what? If I now snap all vertices to cursor, they will snap in all dimensions.
The second question is about using a plugin, but this is my first plugin and it is related directly to this problem, so I post here. In user preferences, I have checked the check box to use add-on “3d view: Align Tools” (maybe this is the solution to my problem with aligning). But after studying the Align Tools wiki page for this add-on, I still cannot find the tools in Blender interface, neither in Toolbox panel on the left nor in transforms panel on the right… Where should they appear?
