Civil 3D User-Defined Contour Analysis

Ever have the need to show a random contour and/or a high water mark of a pond? Using Civil 3D's User-Defined Contour Analysis will make that an easy task.

Example:

We have created a drainage pond but would like to mark the HIGH WATER ELEVATION of 167.55 and display that contour line along with our typical contour intervals.

Here is our pond before:


Select your surface, right click (or contextual Ribbon), and go to Surface Properties. Go to the Analysis tab, on the "Analysis Type" pull down select "User-Defined Contours". In the Number of Ranges type "1" and then select the Add arrow to the right. After the contour has been added to your Range Details click on the "Elevation" and set it to your edge value, in this case 167.55.



*Note: Make sure your surface style has the User Contours" turned ON in the Display tab 


Apply that style to your surface and you should now see the HIGH WATER contour!! Label it as you would any other surface label and/or contour label.


***Note: Need to know the capacity of your pond?? Select your surface and expand the Analyze panel. You will find the "Stage Storage" tool. This tool has many options to help you calculate your basin. 

I hope you enjoy this, check back again soon!!

  1. Noted that the "Dislay" column in the "Surface Proposerties" dialog box permits editing of the display, but the Surface Style Display seems to over-ride these settings, is that correct? Thus if I have several user defined contours that are to be displayed in different color/linetypes, the Style Display over-rides and makes them all match the properties of the Style Display (ie. as in example: bylayer color, Linteype,etc). Is there something I am overlooking or just a 2011 issue?

  2. It has been an issue in all versions of Civil 3D, even in 2012. I will check with a few others just to verify but I believe you are correct.
