Fast, efficient and dynamic design of intersections, kerb returns, cul-de-sacs and knuckles. Include roundabouts with ease. Have multiple design windows open at once. As you move a road string, watch all sections update, intersections update and surface rebuild. Get volumes without effort. Click button outputs to long and cross section sheets and point setout.
Built for large models and a proven performer on large scale road designs including interchanges. Where you find performance issues in other software you'll get lightning-fast speed as you make design changes. Dynamic enough to automate traditional intersections and flexible enough to model complex interchanges via a hybrid assembly and string based approach.
Design your sections to account for all constraints - included are tools to match to surfaces, other strings, continue crossfalls, match to horizontal constraints, and conditionally remove sections. Automate your string vertical design based on minimum pavement thickness, match to surface and more. Build your own models using any collection of profiles.
Design your underground pipe network using a surface or in context with your road designs. Make use of automated rules for minimum cover and slope requirements, with the ability to quickly identify and resolve any conflicting services. Includes stormwater design for pipe sizing and sewer design house connection controls for establishing sewer pipe invert levels.
Grade parcels, building pads, detention basins, wetlands and more. Create gradings directly from polylines and cross section assemblies, with simple corner cleanup tools applied at corners. Apply changing batter slopes, apply alignment controls, and more. Design using a graphical profile design window and/or grid view design window. Fast volume outputs.
The TIN Surface modeling tools let you design whatever you want using any combination of 3D faces, 3D polylines, AutoCAD points and point files. This is a rapid display engine showing contours, labelling and analysis outputs in the drawing. Generate surface analysis tables and export to Civil 3D Surfaces. Generate volume reports and stack surfaces.
