Had some discussions with a user recently on how best to create setting out (stakeout) from their models.

So this next series of posts I will try to enlighten you to what is possible from the box as standard.

Corridor - Points and tables

So you have this lovely model and want to build it.
Contractor wants levels and coordinates every 10m on a straight and every 2m on curves on the junction.(yes junctions!)

You want to have the setting out information on the drawing.

Step one.

Temporarily adjust your corridor frequency to suit this criteria

Set frequency

Main road adjusted

Junction area adjusted

Step two.

Go to Corridor menu and utilities

Export COGO

COGO Points are created in the point group with your default style

As the points are stored in a point group you can now change the style easy to just show a point number
Change the point style to display what you want or numbers in this case

Step three.

From the Points menu, select tables and select the point label style and also the point group that you saved your points to.

Result is a table for that feature line at the interval required.

Next you may want to have a specific table title so to link it with the feature line

Setting Out - Junction 11.png
Right click on the table and go to it properties. Copy the original table style with a new name

Click on the table title (POINT DATA) and enter a new table title.

Resulting table now has the new title

Next repeat the export for the kerb return alignments

For the junction area, when you export COGO, remember that the corridor creation is from the kerb return alignments, so the corridor feature line is actually the CROWN. Also here you can see that you can isolate a specific baseline alignment, rather than the whole corridor.

Step four.

Repeat the exercise for all the feature lines you want to create setting out for.

NOTE

This method creates points from your corridor, however these points are static, i.e. if your corridor is adjusted, your points and tables will not be updated
Therefore do this output when you need to and also name groups etc to suit the design state as a reminder.


Hope this helps.
I will show some other methods in future posts.

  • WHat about point offsetting using this method? Surveyors like to be back from the corridor with about 1.5m offsets.
