How do I merge multiple rows of vertices together? Is there a way to merge multiple rows of vertices together like in the example below?



To looks like this (I manually connected each vertex).
PS: I'm sure there is a better way to model it, but I'm just asking as a hypothetical question which would be good to know.
Just to illustrate @moonboots' point


In Edge Mode CtrlAlt select the edge ring
X > Edge Collapse
