I have a PNEZD .txt file that was used to bring into C3D using Points From a File.
After this, figures were brought in using Import Survey Data with the option Process Linework Sequence= By Import Order.
Some Raw Description edits were then made within the dwg file.
Finally, an Export Points (back to a PNEZD txt file) was made.This file has the Points listed numerically 1-10000.
If a user wanted to Import this file, it wouldn't come in correctly because it has lost the "Import Order".
Is there any way that this "order" could be preserved? Is there a different process that could be used?
Kinda learning this on my own, so bear with me.

I have never heard of a way, but you might be able to get creative with excel?
The points in particular are the centerline of road points (CLN). It seems that some CLN was picked up by survey (1000 point #'s) and then some was picked up again later (23000 point #'s). Example: 1338 and 23170 area is "filling in" the CLN line.
I would suggest creating a point group with the points you want, assuming pt numbers are incrementally correct. Then you can either export the group, or renumber the points and then export.
Another option would be to ignore/remove the points you have and use Create Points>Polyline Vertices - Automatic. This will create points with sequential point numbers.
The following code will export your points in the order of creation, without regard to point number.

Thanks Tim. I'd like to try this but have no idea how to run this or any code. If it is something easy I'd give it a try, but if it's going down another track I would rather not. I think I have some more learning and testing to do in C3D survey area. Thanks.
I would edit the input file with necesary edits. I do this commonly do this for survey data so as to preserve and document any edits made to the data. Typically I comment out the original line, copy and past it to the next line and make an edit there.
Copy the code I posted. Paste into a Notepad document. Save the file as ExportPointsinCreationOrder.lsp.
When in AutoCAD Civil 3D, use the Appload command to find and load ExportPointsinCreationOrder.lsp. Once it has been loaded, type Go and it will run.
I didn't take the time to make dialog calls so it just creates a file called ExportedPoints.txt in C:\. The format is P,N,E,Z,D.
