Avoiding Overlap when Extracting Volumes from Civil 3D Corridors
When placed along an alignment, Civil 3D sample lines slice through corridor models and identify the end areas used to calculate earthwork and structural material volumes. In places where alignments intersect, their respective sample lines may also intersect resulting in duplicate volume calculations.
In today’s installment we’ll explore a way to build custom alignments that serve as match lines for the sample lines used in volume calculation. Ensuring sample lines terminate along common linear segments eliminates the possibility of crossings and avoids overlap in volume calculations.
