Update point elevations with 3-D polyline

[Geoffrey Leiter]

I have numerous points located on a 3-D polyline. All the points have an
elevation of 0.00. I would like to update these points with the elevations
of the 3-D polyline at each location. Is this possible? And if so, how?

Thanks.

Thanks, but thats a big job doing it manually for 200 points. I've decided
to write a small lisp routine to extract the z value of the 3-D polyline at
each node and re-insert it into the node elevation attribute via selection
set.

I think XML2 is a nice program, especially after using EP, but the node
routines are very limited IMO.

Geoffrey,

Am I'm missing something here? Have you tried "create points from
entities" it's on the COGO Pulldown or command: autopnts ? This will
create points in your CRD file.

All right. I did read it again, but it still doesn't give me enough
information.

How where the "numerous points" created in the first place at a 0.00
elevation?

Points were created using draw/locate points (elevations were not known at
this time). Later, a 3-D polyline was created which runs through these
points. Now I would like the points updated with the Z value of the sloping
3-D polyline at each point.

Prior to writing a lisp routine on my own, I figured I would ask if this
ability already existed in XML2.

Take care.

Yes, using the "create points from entities" it's on the COGO Pulldown
or command: autopnts
you'll have to take point protect off, and uncheck avoid duplicates with
existing pts

That only creates *additional* points.

Summerizing the original post again....

I have numerous points..

I'm pretty sure he does not want NEW points.

NO, It doesn't only create *additional* points.
It will automatically overwrite your existing points as long as "point
protect" is off. Otherwise you are prompted to overwite each point, also
it works best if the original points were located sequentially, then
when your running the command you can keep "automatic point numbering"
on, otherwise you would have to uncheck that to be prompted for point
numbers, and don't forget to uncheck "Avoid Duplicates With Existing Pts".

....AND you set the starting point number to the first point number you want to replace, otherwise it creates new points.
