I am prepping a curb and gutter stake out. Several islands in a parking lot. I create a CL file of the island. When I come back and label key points that need to be staked like pc pt corners pcc etc with station labels I am getting duplicate stationing at say the mid point of a bullnose at the pc and pt. I am using Carlson Civil Survey 2020 on top civil 3d. I am new to Carlson so I know I must be doing something wrong.

Sounds like you are seeing an equation where your polyline starts and ends in the centerline routine.

Not sure of your workflow, but here is my workflow teaching a Carlson beginner to compute curb;

1-Import design boc as a 2DP

2-Trace design BOC as a 3dP (There is multiple ways to create the 3dp, import from design, use spot grades, offset 3dp to surface file, explode imported feature line to a 3dp,etc)

3-Offset 3dp 0.05' off 2dp and erase original (this step is not required if you use the selection cycle command in AutoCAD...I don't use it generally...Just an old habit)

4-Use the offset interval command and set it up to how you like it

6-Select the 2dp for horizontal component

7-Select the 3dp for the vertical component

Things to watch for;

The command asks for a starting point number, but doesn't always hold use last so always look at it

Create vertex's at special points you want along the 2dp and the command
will create a point there with create points at vertex's checked.

The angle setting should be to a 100 and not 90 to get corners to stake with double offsets

You can do the command with a 3dp but lose the ability to compute points at vertex's (it does work but if you hit a curve you end up with a million points)

Use revline to get the polyline to stake in the direction you want...Older versions of Carlson only staked to right of the line

Don't have the program compute off surface....It will use the surface elevation at the offset and not at the BOC

Currently I only use Centerline and profile for long roadways with cross section road templates. We are working on moving towards using centerline for export to survpc, but that would mean we don't compute points at all and the field crews would select the point locations.

Thank you. Let me clarify a bit better. So at this point for how they work here elevations are no concern. I have created the poly line using 2dp etc. at the face of curb that’s what they us. No issues there. Then I use the create Ck from poly line my cl file is created. That will go out to the field. No points they will offset themselves at pc pt corners etc. what I do need is to label the stations at the corners pc pt and key points or at a certain station for us to create a cut sheet and grade later. When I use the label station offset on some islands not all it refuses to attach a label at 1 corner and labels everything else including another corner correctly. Then on some island it labels the midpoint the same exact station as the pc and pt and somehow reverses stationing on another island so going up station all is good then all of a sudden the next location gets smaller. I am sure it’s either I have done something wrong but several curb islands work for then some get goofy maybe a glitch. I basically will give a plot of these so the crew chief knows the important points to stake. I do appreciate your write up and will be giving that a try in near future. I am completely new to Carlson cad so learning that.

That is an interesting workflow....but I have no clue. Haven't seen it do that before. Are your 2DP's closed?

Carlson will station your lines according to the direction they are drawn in.

Yeah. I figured out some of the issues. And why it was reversing stationing at certain places. The base drawing I was working from had crissed crossed two arcs like .01 ft so that had the station labels going wrong. I still can’t figure out why a curb island I have like 6 that look just like a basketball free throw line arc at one in rest rectangular. Best way I know how to describe it. But on some of them it will label the starting station wrong the dialogue box shows it correctly so at one corner should be 0+00 the other corner Depending on direction is like 0+12 let’s say. When I snap to the corner of 0+00 it labels it like 0+07. Xxx that’s if the label actually shows up some times it gives the previous stations mid stationing especially on the arc portion. All other labels are working correctly. I simply edit the text and move on. It took me a bit to figure out exactly what it was doing. But it doesn’t do it every one just some of them and who knows lol

Yes sir . Yeah I am a bit ocd so I make sure when I create the center line from poly line I reverse the direction if it’s not going clockwise. Trying to keep things consistent for the crews so all go clockwise as they loop around.
