Survey Terrain Tools earns its place in the superhive library for its focused, deterministic approach to terrain work, handling slope editing, offset construction, and world-space measurement inside Blender rather than through many manual steps.
Survey Terrain Tools is a terrain-focused Blender add-on aimed at survey, civil engineering, and CAD-style modeling. It provides a compact set of deterministic operators for slope-based editing, offset construction, geometry analysis, and world-space measurement, all working directly inside Blender. It's built for workflows where accuracy, control, and predictable results matter more than artistic ones.
The toolset covers setting slope between vertices, applying slope along a line, and single or batch slope edits. Perpendicular extrusion builds offset geometry along angle bisectors, with an Angle Correct Length option that keeps offset width more consistent through bends. Other tools align hidden vertices to a plane in Z, create circle sectors from points and radius, slide vertices by exact world-space distance, and generate intersection edges between selected face planes. Measurement covers edge length, face area, volume, and angles in 3D or planar XY.
Survey-style annotations generate slope labels and drop-direction arrows in percent or ratio, placed at edge midpoints and organized in a separate collection. The add-on requires Blender 5.0 or newer and no external Python dependencies. A demo video is available.
Survey Terrain Tools - Geodetic & Construction Workflow is best for civil engineering modeling, terrain shaping and grading, road and infrastructure geometry, survey-based mesh editing, and CAD-like construction workflows inside Blender.
Survey Terrain Tools - Geodetic & Construction Workflow is completely free to download and use.
Survey Terrain Tools requires Blender 5.0 or newer, so it runs on that release and later versions. The add-on installs without any external Python dependencies, which means you don't need to set up extra libraries alongside Blender. Once enabled, its operators cover slope editing, offset construction, geometry analysis, and world-space measurement directly in the viewport. For confirmation on the exact builds supported and any later changes, check the developer's page before installing.
Survey Terrain Tools needs no external Python dependencies, so everything it relies on ships with the add-on itself. That keeps installation straightforward: you enable it inside Blender 5.0 or newer without downloading separate libraries or configuring outside packages. The toolset then handles slope editing, offset extrusion, aligning hidden vertices in Z, circle sector construction, and measurement directly in Blender. If you want more on the setup steps, the developer's page is the place to look.
Survey Terrain Tools lives in the 3D Viewport under the N Panel, in the Survey tab labeled Survey Terrain Tools. From there you reach its operators for slope editing, perpendicular extrusion, aligning hidden vertices to a plane, cursor-driven edge creation, circle sectors, measurement, and slope annotations. Annotations such as labels and drop-direction arrows are organized into a separate collection. For a fuller walkthrough, the developer provides documentation and a demo video.
Survey Terrain Tools is listed as free here in our catalog. Licensing terms can change over time, so check the developer's page on superhive for the current details before you download. The add-on bundles slope editing, offset construction, world-space measurement, and survey-style annotations for Blender, with no external Python dependencies required. Whatever the licensing, you get the same focused set of deterministic operators aimed at survey, civil engineering, and CAD-style terrain workflows.
