Hi @Everybody

How can I define topsoil in subassembly composer for example cut 10 cm of the top of the soil while the cross section is in the fill mode like this image!?

"Topsoil" is only a shape code. You decide how to proceed if a subassembly point is below or above a target surface (existing ground - EG). If the test point P1 (edge of travelled way - ETW) is above the surface, a P3 should be created that is 0.1 m below P2 (slope staking point).
Therefore, an auxiliary point AP1 is usually created vertical from P1 to the surface. Then check P1.y > AP1.y in a decision.
But in this case, wouldn't you do the same if P1 is below the EG?

Use two Surface Links.. giving the second one a Depth below EG.

Then close the ends and create a Shape for it..
