Polyline Vertex - Changing Elevation

[donaldo]

Perhaps someone can advise how to change the elevation of each vertex on a polyline so that each vertex has a different value. The way I attempted this in the past was to click on polyline, click properties and give each vertex the required elevation. However when I looked back at the values I noticed that every vertex had the same value as the last elevation value entered. is it something to do with ensuring polyline is 3D? Many thanks.

The normal polyline can only have one z value throughout. That is how it is

What you need is the 3D polyline, and I not sure whether LT can cope with 3D

I think by writing the question I discovered the possible annswer but thanks for confirming and my version does have a 3D line though not on the toolbar. Cheers.
