    Jon,

    Evolve does not have an aligning mechanism but you can use a workaround.

    1. Create a line with the first point snapped to the point you want to align with
    2. Now hold the X key and click near the point you wan to align (make sure no snaps are enabled - this creates a perfectly horizontal line)
    3. Edit the length of the line by changing the X value of the line end point 
    4. Now snap the point you want to align with the end point of the line you created.
    5. You can either hide the line or delete it altogether

    thanks,but it is hard to align multipoints.it is easy to align the control points in rhino or alias.

    If this curve is drawn in the top view, select the point you want to move.

    Now in the front view drag the point over to the point you are aligning to.

    Hold Alt and the point you are moving will snap to be in line with the point you are aligning to.

    Jon,

    Here is a brief video of the steps I am taking to align points that I hope will work for you.

    When I drag the point in the lower (front view), I am holding the alt (option) key which makes the point snap to be in line with the point behind it.

    I am on a Mac using Evolve 2016. 

    I hope this works.
