An oldie but a goodie. Worth posting as it can save literally hours for anyone that is manually stringing survey points - (If you don't have Civil 3D set up to automatically process survey data). The drawing used below is from the Civil 3D Essentials book by Eric Chappell.
If you have surveyed a string of points and the numbers are sequential then you can use transparent commands when you are joining them in Civil 3D to speed up the process. Below I have a fence that was surveyed from start to finish (1 to 5 in the image).
There are 27 points surveyed along the fence, starting at point number 123
and ending at 150...
To string these quickly start the 3DPOLY command (or polyline command). Select your start point by clicking with the mouse. When it looks for the end point type 'PN (apostrophePN). Then press enter. Type 123-150 and press enter. Civil 3D will automatically string all the points between the numbers for you.
