LandArchGrade
Grade the Earth. With Love.
An opinionated grading workflow for Rhino that prioritises speed, responsiveness, and beauty.
The grading tool that doesn't exist yet.
There is no best-in-class, real-time grading tool built for Landscape Architects. Every existing option is either a general-purpose CAD afterthought or a clunky bolt-on. We're building the tool from scratch, designed to cut grading time in half and make revisions something you actually enjoy.
Faster grading
What used to take a full day of manual spot levels and calculation now happens in real-time. Move a point, see every slope update instantly.
Revisions made easy
Design changes no longer mean starting over. Adjust your terrain and watch the entire grading model update live. Slopes, drainage, and analysis all in sync.
Built for you
Not adapted from civil engineering or architecture software. Every interaction, every workflow, every output is designed around how Landscape Architects actually work.
Everything you need for terrain design.
A comprehensive suite of terrain modeling, analysis, and visualization tools integrated directly into your Rhino workflow.
Real-Time Terrain Meshing
Constrained Delaunay triangulation engine generates terrain meshes instantly from spot heights, breaklines, and boundaries. Edit any input and watch the mesh rebuild in real-time.
Accessibility Compliance
The first tool to decompose compound slopes into running and cross-slope components. Verify compliance with ADA, BS 8300, and AS 1428.1 standards during design.
Grade Distribution Analysis
Color-coded slope visualization with customizable grade bands. Instantly see which areas meet threshold requirements with green/yellow/orange/red classification.
Walls & Structures
Model retaining walls with configurable height, batter angle, and offset. Add stairs with automatic step generation. All structures integrate seamlessly with the terrain mesh.
Cut & Fill Earthworks
Automatic cut and fill volume calculations with net balance tracking. Get real-time earthworks estimates as you adjust spot heights and design levels.
IFC Export
Export your terrain model alongside all structures directly to IFC. Seamlessly integrate your landscape grading into BIM workflows and coordinate with the wider project team.
From control points to compliance, in seconds.
Define Control Points
Place spot heights, draw breaklines, and define your site boundary. Import from survey data or create design levels from scratch.
Add Structures
Model retaining walls, stairs, paths, and kerbs. Set heights, batter angles, and offsets. All structures snap into the terrain.
Instant Analysis
The terrain mesh rebuilds in real-time with color-coded slope analysis. See grade distribution, directional arrows, and contour lines instantly.
Verify Compliance
Check running and cross slopes against accessibility standards. Review cut/fill volumes. Iterate with confidence before anything is built.
Built for professional workflows.
LandArchGrade integrates natively with Rhino 8 as a RhinoCommon plugin. It includes a dockable web-based UI panel for intuitive object management, property editing, and analysis controls.
