BUILD3D is a revolutionary software tool for constructing 3D analysis-ready geometries. Its powerful feature-based design allows for quick construction of 3D geotechnical models with complex topography or geology, sweeping tunnels or rivers, and 3D geometry from CAD files

  • Seamless Integration; BUILD3D includes the ability to import surface meshes directly from a Leapfrog geological model through Central connectivity. Surface geometry created in CAD software can also be imported as background surface meshes to simplify geometry creation. BUILD3D supports the import of multiple 2D cross-sections from Leapfrog through Central, or through CAD source files.
  • Feature-Based Design; BUILD3D is a feature-based geometry creation tool that allows modifications of a model at any point in the Design History. Changes are quickly and automatically cascaded through the entire model geometry, providing huge time-savings.
  • Powerful Operations; A suite of powerful Boolean operations are available in BUILD3D, including: intersect, cut, merge, and imprint. These operations provide the necessary tools for creating 3D geometries from scratch or modifying geometries imported from STEP files.
  • Clean Mesh Generation; Generate the finite element mesh throughout your 3D domain with the click of a button. BUILD3D automatically produces a clean mesh, removing the need to spend hours on manual mesh adjustments and material and boundary condition assignments.
