In a profile view, display the profile of another alignment that is adjacent to the main horizontal alignment.
Use this option to show one profile in relation to another, such as a ditch in relation to a road centerline.
The general process is first to create separate profile views to display the two profiles. Then identify one profile as the source profile to display in the other profile view, which is known as the destination profile view. In the example of a ditch and a road centerline, let us assume that the ditch is the source profile and the profile view for the road is the destination. When you superimpose the ditch profile on the profile view of the road, you see the ditch elevations with reference to the stations along the road centerline.
When you superimpose a profile, you can set some options in the Superimpose Profile Options dialog box
- Identify the source profile you want to superimpose. Ensure that each profile appears in a profile view.
- Click Home tab
Create Design panelProfile drop-downCreate Superimposed Profile 
.At the Command prompt, enter SuperimposeProfile. - In the drawing, click the source profile line.
- Click the grid of the destination profile view.
- Optionally, on the Limits tab, specify a limited range of stations to superimpose.
Note
If you want the superimposed profile station range to remain fixed, then select the Select Start and Select End checkboxes and the superimposed profile will not react to changes in the station range of the source alignment. If the Select Start and Select End boxes are not selected, then the start and end of the superimposed profile locks to the start and end of the source alignment. If the start or end of the source alignment changes, the superimposed profile updates dynamically.
- Optionally, on the Accuracy tabspecify different mid-ordinate distances for curve tessellation.
- Click OK.
