[Setting up a Deal](https://support.testfit.io/knowledge/getting-started?hsLang=en#setting-up-a-deal) July 20, 2026 # How do I add a grade easement to a site? ## A percentage threshold now flags terrain too steep to build on and highlights it directly in canvas, either persistently via toggle or on hover. To add a grade easement, activate the grade easement tool. Next, adjust the grade to capture the area for the grade easement. Note, the grade easement will prevent any solve within the boundary. ![](https://support.testfit.io/hs-fs/hubfs/image-png-Jul-20-2026-12-22-38-1003-AM.png?width=864&height=571&name=image-png-Jul-20-2026-12-22-38-1003-AM.png) Select "Create # Easements" to generate grade easements. The grade easements will appear under the Sites tab as easements and can be renamed as needed. ![grade_easement](https://support.testfit.io/hs-fs/hubfs/grade_easement.gif?width=670&height=289&name=grade_easement.gif)   - [Getting Started](https://support.testfit.io/knowledge/getting-started?hsLang=en#main-content) - [Interface](https://support.testfit.io/knowledge/getting-started?hsLang=en#interface) - [Setting up a Deal](https://support.testfit.io/knowledge/getting-started?hsLang=en#setting-up-a-deal) - [Site Design & Configuration](https://support.testfit.io/knowledge/getting-started?hsLang=en#site-design-configuration) - [Fundamentals](https://support.testfit.io/knowledge/fundamentals?hsLang=en#main-content) - [Regions](https://support.testfit.io/knowledge/fundamentals?hsLang=en#regions) - [Key Functions](https://support.testfit.io/knowledge/fundamentals?hsLang=en#key-functions) - [Roads](https://support.testfit.io/knowledge/fundamentals?hsLang=en#roads) - [Site Development](https://support.testfit.io/knowledge/site-development?hsLang=en#main-content) - [Mass-Based](https://support.testfit.io/knowledge/site-development?hsLang=en#mass-based) - [Housing - High Density & Gurban](https://support.testfit.io/knowledge/site-development?hsLang=en#housing-high-density-gurban) - [Housing - Low Density & Subdivision](https://support.testfit.io/knowledge/site-development?hsLang=en#housing-low-density-subdivision) - [Housing - Garden](https://support.testfit.io/knowledge/site-development?hsLang=en#housing-garden) - [Industrial](https://support.testfit.io/knowledge/site-development?hsLang=en#industrial) - [Datacenters](https://support.testfit.io/knowledge/site-development?hsLang=en#datacenters) - [Generative Design](https://support.testfit.io/knowledge/site-development?hsLang=en#generative-design) - [Parking](https://support.testfit.io/knowledge/site-development?hsLang=en#parking) - [Retail](https://support.testfit.io/knowledge/site-development?hsLang=en#retail) - [Core-Based](https://support.testfit.io/knowledge/site-development?hsLang=en#core-based) - [Web App](https://support.testfit.io/knowledge/web-app?hsLang=en#main-content) - [Deal Pipeline & Asset Management](https://support.testfit.io/knowledge/web-app?hsLang=en#deal-pipeline-asset-management) - [Deal Actions & Edits](https://support.testfit.io/knowledge/web-app?hsLang=en#deal-actions-edits) - [Reports](https://support.testfit.io/knowledge/web-app?hsLang=en#reports) - [Quantities & Costs](https://support.testfit.io/knowledge/web-app?hsLang=en#quantities-costs) - [Pro Forma](https://support.testfit.io/knowledge/web-app?hsLang=en#pro-forma) - [MCP](https://support.testfit.io/knowledge/mcp?hsLang=en) - [Reports & Exporting](https://support.testfit.io/knowledge/reports-exporting?hsLang=en#main-content) - [PDF Exports](https://support.testfit.io/knowledge/reports-exporting?hsLang=en#pdf-exports) - [SketchUp Export](https://support.testfit.io/knowledge/reports-exporting?hsLang=en#sketchup-export) - [TestFit to Revit](https://support.testfit.io/knowledge/reports-exporting?hsLang=en#testfit-to-revit) - [Account Management](https://support.testfit.io/knowledge/account-management?hsLang=en#main-content) - [Administration](https://support.testfit.io/knowledge/account-management?hsLang=en#administration) - [Account](https://support.testfit.io/knowledge/account-management?hsLang=en#account) - [Latest Release](https://support.testfit.io/knowledge/latest-release?hsLang=en#main-content) - [2026](https://support.testfit.io/knowledge/latest-release?hsLang=en#2026) - [2025](https://support.testfit.io/knowledge/latest-release?hsLang=en#2025) - [2024](https://support.testfit.io/knowledge/latest-release?hsLang=en#2024) - [2023](https://support.testfit.io/knowledge/latest-release?hsLang=en#2023) - [2022](https://support.testfit.io/knowledge/latest-release?hsLang=en#2022) - [Beta](https://support.testfit.io/knowledge/latest-release?hsLang=en#beta) - [FAQ](https://support.testfit.io/knowledge/faq?hsLang=en) - [Troubleshooting](https://support.testfit.io/knowledge/troubleshooting?hsLang=en#main-content) - [Issues](https://support.testfit.io/knowledge/troubleshooting?hsLang=en#issues) - [Errors](https://support.testfit.io/knowledge/troubleshooting?hsLang=en#errors) [![Chill listening crop-3](https://support.testfit.io/hs-fs/hubfs/primary%20wordmark.png?width=124&height=40&name=primary%20wordmark.png "Chill listening crop-3")](http://testfit.io?hsLang=en) Copyright © 2025, TestFit
