I have over 2000 spot elevations on the Y-axis (point and RL number). I want to move these points to their correct RL. Is there an efficient way to do this? Any help would be really appreciated!
I have been struggling to create site topography. For context I have been given a site survey in 2d . It’s a very big site (over 2000 spot elevations) and I wanted to know if there is a way I can efficiently move the points in the z-unit by the numerical value of the spot elevation next to it. From there I will go on to make the 3d topography in grasshopper. If you had any insights at all that would be great!
If you are able to extract those spots + numbers + maybe colours out of a file, they can be turned into lists, and you can work on them in grasshopper.
So first steps are:
- please upload an example of map + extracted points.
- upload the grasshopper file, you are working with, so we see how you approach the question.

Try to extract text value and xy coordinates as shown in this tutorial https://www.youtube.com/watch?v=MulDzYKMAzE
the main issue generally is to make sure each text-coordinate is somehow linked to the correct 3D point… it happens many times you count the points and have like 1K then count the text tags and you have like 950… what do we do then? 
is it fine if each 3Dpoint gets moved +Z by the value indicated by the closest text tag?
if yes, you’ll be fine with something as easy as this:
the visual check is very useful to fast understand which elevation each point is inheriting
