How to automatically adding z dimension in vertex editor from field attributes

Question

I have geo-coordinates x y and z value, when I created an 3D shapefile, how can I automatically make the z value into Vertex Editors' z dimension??

Is v.extrude what you want? See: gis.stackexchange.com/questions/254710/… — BERA, Aug 15, 2018 at 5:40

Use the IPTZ column as the input for "Name of attribute column used for height" parameter.

I am able to make all "Z" vertex value through v.to.3d, Then I used Plugin Point2One, which make it become 2D Shape file with lines again. So I used v.to.3d again, now this time it made the Z value the same. My two geo points have different altitude, but v.to.3d reads only one.

I don't think I understand what you are saying. v.to.3d is only applying one height? Did you choose the field containing a z value or a constant value?
