Profiles display a red 'tick' mark at the structures to indicate the maximum hydraulic grade over the course of the simulation. Is it possible to display this as a line, so as to visualize the max HGL 'envelope'?
A maximum HGL 'envelope' can be seen in profile view by making the corresponding line series opaque in the Chart Options. This will cause the profile to display a line between the marks. The minimum of such envelope would be the starting water surface elevation, or pipe inverts.
1) Open the profile, click the Chart Settings button in the upper-left corner and choose "Chart Options"
2) Click the "Series" tab at the top row of tabs, then select "Max HGL" from the dropdown list
3) Set the "transparency" to zero
4) Click the colored box in the upper-right corner and change the color (the default red color will otherwise be the same as the EGL line)
5) Click the Close button
