Conversion

Mesh from CAD Body

Mesh from Implicit Body
Creates a Mesh from an Implicit Body. Preserve sharp features by choosing the Sharpen option. Reduce the triangle count of the final result by choosing the Simplify option. Switch to the block overload for more inputs including Sharpening iterations and a region to localize sharpening. This version has a higher computational overhead than Mesh from Implicit by DC, but can handle more complex geometry and produces cleaner meshes.
Mesh from Implicit by AT
Converts an Implicit Body to a Mesh using Adaptive Tessellation. This method may significantly reduce computational and memory overhead compared to traditional methods, especially when finer tolerances are required. It achieves this by creating fewer triangles in flatter or less complex regions, resulting in a lower overall triangle count. However, this optimization can lead to a less regular and lower quality mesh in certain areas unless remeshing is enabled.
Mesh from Implicit by DC
Converts an Implicit Body to a Mesh using dual contouring. This version has lower computational overhead than Mesh from Implicit Body, however the result may contain self-intersections and non-manifold edges or vertices. Use Mesh from Implicit Body when a clean mesh is required and/or for the option to sharpen specific regions.
