🛣️ [Civil 3D] Generate Road Corridor
Draw your road centrelines and Allsite builds the full Civil 3D corridor for you, including widths, curb returns, T and cross junctions, knuckles and cul-de-sacs. After a design run, Rebuild Corridor re-levels the road edges. More information found here.
💧 [Civil 3D] Water supply design in Service AI
Service AI now designs water supply alongside storm and sanitary. It lays the mains, a service lateral to each lot and hydrants, and loops the mains so no single feed serves too many lots. Results load into Civil 3D as a pressure network. More information found here.
🧱 [Civil 3D] Level AI what-if finds the fewest walls
When a site can't grade with the walls as drawn, the what-if run now looks for the fewest retaining walls that make it viable and balanced. You can preview the proposed walls before applying them.
⚡ Level AI and Service AI runs are now up to 3× faster.
Various bug fixes and security improvements
September 2026
🏘️ [Civil 3D] Layout Assist lot generation and potential grade breaks
Generate Parcels subdivides your site into lots from your lot product table, and Generate Potential Grade Breaks proposes retaining walls along the lot lines for you to promote. Lock any generated lot you want to keep across re-runs.
📈 [Civil 3D] Constraint profiles: see why a site is non-viable
When Level AI can't find a viable design, it now draws an engineering long-section along the worst constraint line through the site. It shows the minimum and maximum design profiles, the grades, and the grade breaks that set them. More information found here.
⚙️ [Civil 3D] Settings Report
After each run, see which values in your model differ from your project settings, select and zoom to the features involved, and put any of them back to the default in one click. More information found here.

🤖 [Civil 3D] AI Assistant run cards
Level AI, Service AI and Layout Assist runs now report in the AI Assistant pane instead of pop-ups. Each run gets one card with severity badges, unread markers and a count of what was produced.
🪚 [Civil 3D] Saw-tooth overland flow paths
Set an overland flow path to Saw-tooth Inlets and Level AI puts a low point on each inlet along it, with high points between. This works well for carparks and large paved areas. More information found here.
🗺️ [Civil 3D / Web] Live road design view during Level AI runs
While Level AI runs, the job progress card shows the road design as it develops: high and low points with their levels, road flow and active overland flow paths. You can check your profile controls before the run finishes. More information found here.

🏠 [Civil 3D] Walkout lots in Level AI
Level AI now designs walkout basement lots, with upper and lower platforms held at the step you set. More information found here.
💧 [Civil 3D] Service AI pipe long-sections
Service AI results now load pipe profiles into Civil 3D, with the hydraulic grade line drawn on every storm and sanitary pipe.
🏷️ [Civil 3D] Automatic design labels
Level AI results now label the falls across your single-family lots, with fall lines and spot levels drawn on the proposed surface. More information found here.

⛰️ DEM surface support
Detailed DEM surfaces can be used directly with Level AI without any simplification required. More information found here.
May 2026
💦 Service AI release!
Service AI can now be run from Civil 3D generating full storm and sanitary pipe networks compliant with your local engineering requirements.
More information on how to set up your model for a Service AI run found here.

⚠️ [Allsite.ai Web] Usage dashboard and alerts
You can now visualize token usage and set alerts at organization level and project level, more information found here.
🚧 [Civil 3D] Ditch support in Level AI
March 2026
🚚 [Civil 3D] Truck Bay support in Level AI
Commercial site developments can now add a truck loading dock to sites with a few clicks in Civil 3D. Simply draw a retaining wall along the edge of the building, set the height, and run Level AI.
February 2026
🤖 [Civil 3D] Allsite AI Assistant release
🛣️ [Civil 3D] Road Corridors without using Civil 3D intersections
Level AI now allows engineers to draw corridors only for straight road sections and use polylines to define curb return locations within intersections, bulbs, and cul-de-sacs.
Full step by step instructions provided here.
🛣️ [Civil 3D] Combination of corridors and Layout Assist roads
Useful for commercial sites and car parks, feature lines are output for Layout Assist roads, and regular Civil 3D subassemblies can be used with Allsite simple roads.
