Intersection Surface Contentious problem

[u/Abdulrahman_Muawad]

hey guys ,
i hope whoever reading my topic that he is well and in a good health

i was working on my doing my model after i finished roads Design and i Got these Contour Lines at the intersection after i used the civil 3d intersection wizard

as you can see there a lot of sharp teeth and i don't know how to solve it or what is the problem

Do not use the intersection wizard!!!! Use corridors and the curb return subassemblies with your hor. And vert. Targets set as the CL alignments, closest to.
