Vehicle tracking

Use swept path analysis to speed planning and evaluate safety standards compliance. Animate vehicle paths with 2D or 3D animations using multiple camera angles. (video: 20 sec.)

Stormwater and sanitary sewer

Model storm and sanitary sewer systems. Analyze networks to resize pipes, reset inverts, and compute energy and hydraulic grade lines according to HEC-22 standards.

Stormwater analysis

Integrate stormwater and wastewater analysis during planning and design of urban drainage systems, storm sewers, and sanitary sewers. (video: 39 sec.)

Pressurized utilities

Lay out horizontal and vertical 3D design of pressure networks. Model deflected-curve pipe segments and use design and depth checks to meet project standards. (video: 11 sec.)

Design automation

Use a visual programming application to generate scripts that automate repetitive and complex tasks. Save these scripts in a library and reuse them as needed. (video: 1:49 min.)

Materials and quantities

Use materials and sectional or profile information to create reports for volumes along an alignment, comparing design and existing ground surfaces, and quantity takeoff. (video: 13 sec.)
