How to Convert TER to SAT?

Learn how to convert TER to SAT quickly and accurately with our step-by-step guide and industry-leading tool:

  1. 📥 Download and Install

    Download and install Autoconverter on your system. This application will let you to convert your TER files to SAT format - no additional CAD software required.

  2. 📂 Open Your TER File

    Go to File > Open… to load your TER file (*.ter), or drag and drop it directly into the application window. The model loads into the 3D viewport for inspection before converting.

  3. 💾 Save As SAT Format

    Go to File > Save As…, select SAT (*.sat) as the output format, choose your destination folder and filename, then click Save to complete the TER to SAT conversion.

TER TER File - Terragen Terrain Format

A TER file is the native terrain format for Terragen, a high-end landscape rendering and simulation tool. TER files store elevation data, procedural textures, and environmental settings to create realistic digital terrain models (DTMs) for visualization, animation, and VFX workflows.

Key Features of TER Files

  • Terrain Data: Encodes high-resolution elevation maps using 16-bit grayscale values for precise topography.
  • Multi-Texture Support: Includes diffuse, specular, bump, and displacement layers for natural surface rendering.
  • Procedural Nodes: Utilizes a non-destructive node-based system for flexible terrain editing in Terragen.
  • Landscape Fidelity: Ideal for creating mountainous landscapes, valleys, rivers, and erosion patterns in realistic detail.

TER File Conversion

Easily convert TER terrain files to 3D formats such as OBJ, STL, DAE, SKP, and STEP using Autoconverter and Automesher Application. These tools use the Open Asset Import Library to ensure reliable terrain data extraction, preserving elevation and surface information across 3D modeling, GIS, and CAD platforms. Export your Terragen landscapes and integrate them into your digital production pipeline today!

SAT SAT File - Standard ACIS Text Format (.sat)

SAT files are ASCII-based 3D modeling files created using the ACIS geometric modeling kernel, developed by Spatial. Widely used in CAD applications, SAT (Standard ACIS Text) files store exact geometry and parametric data for solid modeling. This format enables accurate data exchange between leading CAD software such as AutoCAD, SolidWorks, Fusion 360, and Revit.

Key Features of SAT Files

  • High-Precision Geometry: Encodes accurate B-Rep (Boundary Representation) data using NURBS surfaces and curves.
  • CAD Interoperability: Supports seamless cross-platform exchange between AutoCAD, SolidWorks, Rhino, Revit, and other CAD tools.
  • Feature-Rich Modeling: Retains advanced design elements like fillets, lofts, extrusions, blends, and Boolean operations.
  • Readable Format: Human-readable ASCII text file that simplifies debugging and version control in collaborative workflows.
