The update included advanced terrain modification tools (e.g., creating virtual copies of terrain without duplicating large datasets) and vector editing tools for bridges and piers.
Minimum 2.5 GHz; however, a 3.4 GHz multi-core processor is highly recommended for 2D modeling to handle mesh computations efficiently. hec-ras 5.1 download
Minimum 8 GB, but 16 GB to 32 GB is recommended for large datasets and complex 2D areas. The update included advanced terrain modification tools (e
