Hi Luis, right now you can use the Align tool a couple of times to do that - Align will line up one dimension (like horizontal or vertical in the viewport you are using) to the specific point that you pick.

I do plan on adding in some more tools for point editing in the future though, and some method to set all selected points to one value would probably be a part of that.

It is not good to collapse points on the same curve down to each other though.
