About the CPD course
In this course: you will learn how to grade a superelevated intersection: Superelevated intersections can present a grading challenge in Civil 3D as the pavement cross slope varies through the intersection: To accurately grade an intersection: where one or both of the intersecting roads have a non-standard” cross grade: you will need to use offset and/or elevation targets to override the default offsets and/or cross slopes: To create these targeting features: and maintain a dynamic intersection model: you can use a setup surface: The grading example presented in this course addresses a T-intersection: where only the primary road is being superelevated: The same grading principles can be applied to 4-way intersections: where both roads have non-standard cross grades:
