Surface Plot (Beta)

Surface Plot

  • Surface Plot (Beta) block is used to shade implicit bodies with any scalar field, either user-defined or imported from an external source. You can visualize data directly on their implicit bodies to investigate metrics such as performance and manufacturability. You can also use the combination of the section cut feature with this block to visualize results within the implicit bodies.
  • Shading implicit bodies with simulation results, pore sizes of lattice structures, and overhang locations are typical use cases for this block.
  • Block Name: Surface Plot
