Abstract
In example embodiments, anomaly and change detection software of a cloud-based design review service is provided for detecting anomalies and/or changes in 3D roadway models. The software analyzes the constituent meshes of the 3D roadway model that represent components and extracts template drops at locations along a horizontal alignment to produce an ordered list of template drops. The software then looks to differences in depths, widths, cross slopes and/or other geometric properties manifest in individual template drops, or between preceding/subsequent template drops of the ordered list, to detect anomalies and/or changes. Indications of the components associated with the detected anomalies and/or changes are displayed in a visualization of the 3D roadway model in a user interface.
