Abstract
To improve quantity calculation efficiency for long-distance canals with complex and variable cross-sectional forms,and to realize forward design and parametric modeling,the Autodesk Civil 3D subassembly composer was applied.Based on object-oriented and visual parameter-driven workflows,parametric subassemblies were developed for different canal cross sections,enabling automatic judgment of excavation and filling conditions according to terrain.Accurate three-dimensional canal models were constructed in Civil 3D,allowing precise quantity calculation in a 3D visualization environment.The proposed method provides a reference for parametric 3D modeling and efficient quantity extraction in similar linear engineering projects.关键词
