C3D How to
Overview: Create layout profiles using various profile creation tools within an existing Profile View. Edit profiles using commands on the Profile Layout Tools.
Software: AutoCAD Civil 3D 2016, NRCS C3D 2016 template
Prerequisite: A Profile View needs to exist in order for a Layout Profile to be created. Usually a Profile View has already been made in the process of creating a Surface Profile.
Creating a new Layout Profile Profile creation options are found on the ribbon via Home … Create Design… Profile... Profile Creation Tools and Create Profile from File are 2 of the options.
Profile Creation Tools
Start the Profile Creation Tools to create a new profile. Select an existing Profile View that you want to draw in. Input a Name for the profile and set the Style of the profile line. Click Ok and the Profile Layout toolbar will open up.
Profile Layout Toolbar
Draw Tangents
Use Draw Tangents to start drawing your profile. (You need to draw from left to right.) It will be asking you to click to the starting point of your new profile. You can do that by clicking or snapping in the profile view or you can use Transparent commands.
Transparent Commands You can select a Profile transparent command to set the points more easily or accurately than clicking into the profile view.
You can only have one transparent command going at a time. If you want to switch to a different one you need to press ESC to quit out of the active transparent command before going to another one. You can tell that you have a transparent profile command running by looking at the command line where you will see “>>” to the left of the command that is active. E.g PSE >>Specify Station: You should ESC out of the transparent commands first in order to quit out of the Draw Tangent command.

Four of the transparent commands that might be most useful.
Profile: Station & Elevation
Profile: *Grade & Station
Profile: *Grade & Elevation
Profile: *Grade & Length
*These can’t be used for the first point of a profile.
Description- Profile: Station & Elevation – For this point of the profile: Input the profile station, then the elevation either by keyboard input or graphically clicking or snapping. *Profile: Grade & Station – For the next reach of the profile: Input the grade, then the ending station. *Profile: Grade & Elevation – For the next reach of the profile: Input the grade, then the ending elevation. *Profile: Grade & Length – For the next reach of the profile: Input the grade, then the distance.
There are some more advanced transparent commands for Profiles too.
Profile: Station from Plan
Profile: Station & Elevation from Plan
Profile: Station & Elevation from COGO point
These let you “reach” into the plan view of the drawing in order to grab stations and elevations for your new profile.
Convert AutoCAD Line The Profile Layout Tools toolbar has a Convert AutoCAD Line tool. It works on Lines but not polylines or 3D polylines. You can convert 2D and 3D polylines to lines by exploding them.
Profile from an external file
There is also an option to Create a Profile From a File.
This requires a space delimited file with no header and a series of station and elevations of the profile. The stations must be in ascending order. The file needs to have a .txt extension.
Sample file: 0 1140. 200 1136. 700 1129.
C3D How to
Create the Profile of a Pond Pipe
- Create a profile view of the Embankment, Ground, and Core Trench along the CL Pipe alignment using the Profiles & Sections document.
Determine the station and elevation of the CL of the dam, and downstream toe of the dam. Use Profile View labels to label stations & elevations manually in a profile view.
- Click Annotate… Labels & Tables… Add Labels… Profile View… Station Elevation..
- Click the Profile View grid.
- Right-click Midpoint to the station of the CL dam. Press Enter
- Right-click Midpoint to the elevation of the top of dam. Press Enter The label appears.
- Right-click Endpoint for the station of the toe of dam. Press Enter
- Right-click Endpoint for the elevation of the toe of dam. Press Enter The label appears.
- When done Press Enter Verify that these elevations are consistent with the elevations used in the pond design software. (Eg. WinPond, SITES)
Use a spreadsheet or manually compute the station and elevation for the flowline of the pipe: Pipe flowline Station Elevation Inlet Elbow Outlet
Create the Flowline of the Pond Pipe
- Click Home … Create Design… Profile... Profile Creation Tools
- Select the Profile View of CL Pipe. A Profile View is the grid holding the profiles.
- Alignment = CL Pipe
- Input Name = { FL 12 inch pipe }
- General: Profile Style = Flowline (??)
- Label Set = Standard
- Click OK
- From the Profile Layout Tools click Insert PVI
- From the Transparent Commands Toolbar click Profile: Station & Elevation
- Select the Profile View of the CL Pipe.
- Input the station value of the pipe inlet. Press Enter
- Input the elevation value of the pipe inlet. Press Enter
- Input the station value of the pipe elbow. Press Enter
- Input the elevation value of the pipe elbow. Press Enter
- Input the station value of the pipe outlet. Press Enter
- Input the elevation value of the pipe outlet. Press Enter
- Press ESC. Press ESC.
Copy the pipe flowline profile and raise to the top of pipe elevation.
- Select the Profile of the Flowline of the pipe.
- Right-click Basic Modify Tools… Copy…
- Input {d} Press Enter
C3D How to
- Input { 0,0 } Press Enter.
- Select the copy of the flowline profile.
- Right-click Profile Properties
- On the Information tab change the name to { Top of 12 inch pipe } Click Ok.
- Right-click Edit Profile Geometry
- Click Raise/Lower PVIs
- Input the Elevation change as the pipe diameter. E.g. { 12” }
- PVI Range = All. Click Ok.
- Close the Profile Layout toolbar.
To switch a label below the profile line (optional)
- Select a grade label. Labels.. Modify… Flip Label…
- Select a grade break label. Right click Edit Labels...
- Change the style for the Grade Break type to Grade Break. Click Ok.
- Select a grade break label. Labels.. Modify… Flip Label…
See the Profiles & Sections document for additional labeling options.
