When I have a couple of new points to add the the surface, or re-add when I took them out, I'd like to have C3D use the point elevation. Instead it uses the elevation at that point on the existing surface and does not use the slightly different elevation of the actual point.
At which point, pun intended, I need to manually enter the point elevation. I have tried this with ONSAPZ set to 0 and the point style using the 'Use Point Elevation' set correctly in 3D Geometry tab.
I would hope this is possible, and perhaps I am missing something glaringly obvious.
Thanks,
Hi Mortimer,
"...a couple of new points to add..."
Additional survey shots? How are you adding the points to the surface?

The usual case is creating a point group.
However, sometimes I notice a point that appears to be messing up the surface. So I'll use the 'delete point' option under surface edit. At times it may be more than one point.
Occasionally I'll realize that one or more the points removed from the surface needs to be put back in. I'd like to have C3D recognize the elevation when using the command 'Add Point' in the surface Edit function.
Thank you for your response.
I've never done this but I believe it has a good chance of working. On the Surface Properties box, in the Definition tab, there should be a list of edits in the lower pane. Unchecking the Delete Point edit should bring that point back at the original elevation.
If you're happy with the results. Right click on the edit and select "Remove from Definition".

Thank you Allen, I had not thought of that.
What I am getting from your reply is that C3D does not have a way to acquire the elevation from the point entity itself, even when the point style uses the point elevation in the 3D geometry tab of the style dialog. This is unfortunate if true.
If you're adding new Cogo Points to a Point Group that defined a Surface or adding them directly to a Surface. Civil 3D should respect the point elevations.
However the commands in Surface Edit deal with Surface Points not Cogo Points. So the command doesn't know anything about Cogo Points. I've often suggested that the command be modified so it would pick up the elevation of a Snap point; endpoint, node, center, etc.

Using Point Groups works fine for the surface creation.
My use case in editing is an annoyance, not a show stopper.
Thank you for your replies.
Yes. It is annoying.
BTW. Anyone who agrees is welcome to follow the link above and vote for my idea to modify the command.
