Making an earlier post on 3-line profiles more clear.

It is very common in Southern California and some other areas in the United States to have 3-line profiles represented on drawing sheets. A 3-line profile generally consists of a profile that shows the existing ground line with the finished ground centerline as well as two other profiles that each show the existing ground along with one of them showing the Left Top of Curb and the other showing the Right Top of Curb.In Civil 3D, there is not a command that will automatically create a 3-line profile, but here is a simple work around...Create your first profile by using ProfilesàCreate from Surface. As normal, add the data and select the Draw Profile View button...

In the Profile View dialog box, you may want to keep bands for the bottom profile view of the 3-line profile.
















Next, use the ProfilesCreate View command to create the other two profiles. Notice in the below screen capture, that you should consider turning off the bands for two other profiles and make sure to choose the upper left point of the grid of the previous profile view…
















Once you create the three profile views, you should check to make sure the style is correct. For instance, you may want to turn off the graph title. This can be done by clicking on any profile view, then right clicking and selecting Edit Profile View Style






Once you have the three profile views with the proper style, you can begin to layout the three finished ground profiles within each of the three views. Use the ProfilesCreate by Layout tool to create your first profile.

Instead of creating all three profile views with the Create by Layout tool, you could create the last two profiles using the following method. Go to ProfilesEdit Profile Geometry. When prompted to select an FG profile, select any FG profile even though it currently exists in all three profile views, they are all really the same profile. When the following toolbar appears, select the Copy Profile button…




When the Copy Profile Data dialog box appears, ensure the Create new Profile option is selected and hit OK. Do this exact process again, to create a third FG profile.

If you look in the prospector, you will see two additional profiles with the name of Layout1 and Layout2. You can rename these profiles by right clicking on them and selecting Properties.











Next, go back to ProfilesEdit Profile Geometry and select any FG profile in any view. Based upon draw order, it will select the Layout1 or Layout2. Once the Profile Edit toolbar appears, choose the Raise or Lower PVI’s button as shown below. Proceed to move up and down the Layout1 and Layout 2 profiles. It is of course very important for you to edit these profiles to ensure the proper design of these profiles.




Now that all the profiles are designed, it is time to turn off profiles in other profile views… Right click on one of the profile views and select Profile View Properties. When the dialog appears, select the Profiles tab. You will notice that you can control which profiles appear in this profile view. In the below, we want to see only the EG and FG, not the Top of Curb profiles…








Following this, you will need to highlight then right click on the two other profile views. One would show the EG with the left TOC and the other would show EG with the right TOC. The result might look like the following…
