Good Day!
I have a line with 14555 survey points along it, I have found the total distance and need to travel back 118.688 KM back along this line then extract the points from the drawing and load it into a new Dwg. How would one travel back along this polyline the 118.688 KM needed?
Thanks! 🙂

Can you make an alignment out of it, then just use the station-offset transparency tool to locate the point? That seems to be the quickest way.
You could create an alignment from the pline and then use station/offset to find where the station in question is.

The problem I am having is there are so many points that my computer cannot handle the alignment creation, I have split the points into five separate files and created alignments with those but then the meterage is incorrect on the alignments... I'm kinda stuck 😞
For each of the files, did you start the alignment station where the last alignment segment ended? That would be very important to keep the stations correct. It should still work as long as the stationing for each segment is concurrent with the previous. You should be able to pull the ending station from each segment and insert it as the beginning station for the next.
Easier way would be to put the alignment all in one file and use dynamic reference to include it in the other files with the points.

I am unfortunately unable to share due to the sensitivity of the information, Also now it has decided that when I try to open or save the explorer does not open it it stuck in the command line?
If you can get Civil3D to open again, you can adjust the starting station of each alignment segment by going to the alignment properties, the station control tab, and simply typing in the start station. You will get a warning about adjusting the station control and it's effects, but that is OK. The same tab also has the ending station in the station information section for the next segment.

Check that FILEDIA is set to 1.

Draw a line. When prompted to enter a point, type 'SO (take note of the apostrophe). You'll be prompted to select your alignment, station and then offset. After you've done so, press Escape ONCE -- it'll start the line at that station/offset (the offset can be zero).
That will tell you where the station is. Go from there.

Draw a circle centered on that point. As you drag it out when prompted to choose a radius, watch to see which point shows up inside the radius first. The first one is the closest.

Just taking the subject by itself. You could get the location a certain distance from the end of a polyline using either the Measure or the Lengthen command. Use 118.688 as the measure distance in the first case. This will put a node every 118.688 KM along the polyline. The first one from the end you start from is your mark.
Use -118.688 as the delta in the Lengthen command and that will shorten the polyline by 118.688. If you need the original polyline intact. Make a copy and Lengthen the copy. The end will revert 118.688 along the polyline and the end will now be your mark.
All the advice regarding Alignments and Stationing is valid and very useful to know. These two techniques fall under my Quick and Dirty methods. Using only basic AutoCAD commands.

Go into your Alignment Style-->Display Tab-->Turn off the 'Warning Symbol' feature.
What do you mean 'survey points box'?
These ones here, Are they a critical error message?
