# Set vertex position along axis so it be equal another's position

There is a face, that consists of few vertices, and initially all of them was coplanar, so the face was parallel to the floor (XOY).

But I moved one vertex along z axis, so now face is not parallel.

How can make z axis value of some vertex be equal to another's vertex z coordinate?

• you could flatten all the vertices with a SZ0 but it may deform the face, which you may not want, you could also move along Z and snap to another vertex? Commented Apr 24, 2022 at 11:01
• @moonboots, can You describe both approaches in more details? Commented Apr 24, 2022 at 11:04
• sure but could you show a before and after with a clear view of your mesh? Commented Apr 24, 2022 at 11:04
• @moonboots, before and after what? Also the whole mesh is pretty large, it is plane of terrain for a game Commented Apr 24, 2022 at 11:14

Supose you want set the z = 1 of this 4 vertices

Scale to z=0

change z=1 in N-panel

If you've moved your vertex along Z, activate the Snap option (or press Ctrl when you'll want to snap), and choose Snap to Vertex:

Select the vertex, press GZ to move along Z, point your mouse cursor towards the vertex which you want to align with, it will snap:

Or select all, make a vertex of the coplanar faces active, choose Active Element in the Transform Pivot Point panel, and SZ0:

• Thanks, but X Y was first, and it also works Commented Apr 24, 2022 at 11:18
