I want to constructing road on existing embankment with surface width varies from 14 to 22 m and side slope also vary from 1:2 to 1:4, the design assembly consist of 7.5 m carriage way, 2m shoulder, and side slope 1:2, I create surface corridor for top and bottom with boundary to daylight for both and for the target I create surface from points of the base of existing embankment using as a target surface
The problem is how to inform the software to cut the soil embankment out of design assembly because now the side slope extend to the target surface and stopped don’t continuous horizontally to the end of embankment edge.
..because now the side slope extend to the target surface and stopped don’t continuous horizontally to the end of embankment edge...
Use DaylightMultiIntercept
Asalam Yasser,
I believe there are several ways you can arrive to your intent. Here is one way I think it can be achieved;

Asalam Yasser,
I am assuming you already have or can create the following three surfaces and features;
A - Bottom of the existing embankment, which by the way, you have used as the target surface (the black line in your attachment).
B - The Datum surface of the design corridor (the blue line in your attachment)
C – Top of the existing embankment which you can create from points of the top of existing embankment that you used as a target surface (the dotted red line in your attachment)
T1 and T2 are the left and right "end of daylight points" of your design corridor. Over here, we call them toe lines. Actually, these should be the extreme points of your corridor assuming you have no subassemblies after the daylight slopes.
Steps (as you requested)
(In a nutshell, you are combining the Bottom of the existing embankment surface and the Datum surface of the design corridor)
Hope you are aware of the procedures of computing material quantities. In case you don’t, the tutorial resources can guide you very well there.
Unfortunately this seems so non-dynamic.
I would also suggest that you take some time and study the Rehabilitation/reconstruction Subassemblies. These could perhaps get you a dynamic /automatic workflow.
