LandArchGrade
Grade the Earth. With Love.
Coming May 2026
An opinionated grading workflow for Rhino.
See It. Shape It. Instantly.
LandArchGrade generates a live terrain surface from your spot heights, breaklines, and structures. Slopes are colour-coded against thresholds you set, contours and flow arrows update live, and every edit happens directly in the viewport. Drag nodes, adjust elevations, move structures. The terrain rebuilds as you work.
Every Structure. One Surface.
Ten dedicated terrain object types, each purpose-built for how Landscape Architects model sites. Walls, stairs, paths, ramps, and more. All integrate seamlessly into a single terrain mesh.
Set precise elevation values at any point on your terrain. The foundation of accurate grading design.
Compliance Built In.
Ramp compliance is checked live as you design, with built-in presets for ADA/IBC (US), BS 8300 (UK), AS 1428.1 (Australia), DIN 18040 (Germany), Arrêté (France), and Bouwbesluit (Netherlands). Select your region and LandArchGrade handles the rest.
Gradients, cross-slopes, landing lengths, and ramp dimensions are all validated against your chosen standard. You see exactly where a ramp passes or fails, right in the viewport, while you're still drawing it.
Balance Cut and Fill in Real Time.
Adjust your design levels and watch cut and fill volumes update instantly. The live net balance readout tells you exactly where you stand, so you can fine-tune grades until earthworks reach equilibrium.
When you're ready, export the cut and fill plan straight to DXF with volumes attached automatically. Hand your contractor a clear, detailed drawing without any manual annotation.
Export Everywhere.
Take your terrain model into BIM workflows and coordinate with the wider project team.
IFC
Export terrain and all structures to IFC4 for full BIM integration, with IFC4x3 available for infrastructure-aware workflows.
DXF
Generate DXF drawings of your grading and terrain objects automatically. The terrain becomes your source of truth, informing all of your drawings downstream. Compatible with most CAD software.
