The project involved several challenges, one of which lay in modeling large, branched elements that form a complex system. To manage this, the road and bridge were divided into sections. When one part of the road surface overlapped another, the sections were split into different elements. This ensured the correct functioning of Revit tools and enabled the software to process each section independently, thus preventing conflicts between overlapping geometry.
Another challenge was the variations and inconsistencies in point cloud data due to factors such as data resolution and scanning angles. To solve this and align the model’s road surface with the real elevation marks represented in the point cloud, each part was modeled using the “Floor” category, with a regular system of internal edges.
To maintain the accuracy of the earth’s mass while working with the road surface’s complex geometry, the overlap had to be managed carefully — particularly when dealing with irregular road shapes or changes in elevation. Therefore, topography was modeled using the “Mass” category by outlining earth profiles with regular steps and then creating surfaces based on these profiles. To ensure the earth’s mass elements matched perfectly with the edges of the road surface, the earth model was initially created with some overlap. The edges were then trimmed with a void, precisely matching the road surface edge shape.
Additionally, at the client’s request, all bridge railings were modeled with a high level of detail, with posts and rails matching the point cloud as closely as possible. Additionally, all road signs were modeled to accurately reflect the real surroundings.
