I requested additional survey to be done for me project. The surveyor added the csv data into the field book for my terrain file. This caused my current vertical profile to be dramatically shifted from where it should have been. Is there a way to avoid this? Did the surveyor mess up when importing the data? was it because the vertical alignment was ruled/snapped to the terrain that when new data was added behind it the whole profile moved?
Originally the vertical profile was only over the terrain section to the right. When that left chunk was added (additional survey imported) it stretched it back to the left.
It should only be over this section. It was snapped to the original ground when I had placed it.
I ran into a similar issue in Civil 3D where a existing was linked to elements in another file. Someone did not know what these elements represented and removed them and it broke my terrain. So we started publishing terrains to a stand-alone terrain element which represented a snapshot of the terrain when it was published.
In you case, you could export the alignment to LandXML and when that is imported into a new file, it would be independent of the source terrain and profile.
It might be also possible to remove the rules using the geometry editor or using a direct tool to remove rules. I am still learning the nuances of Open Roads Geometry, so some of these suggestions may not be available or work exactly as I suggested.
But the export and import via LandXML should work. I did something similar there I used the best fit for a road, but at one end of road, the profile was on a raised median and I could not figure out how to modify the profile to manually adjust those areas. By using the LandXML approach, I had an unruled vertical that I was finally able to modify.
