Creating the SubD Hybrid Model

You can also use the Auto Skin tool to create the SubD hybrid model from faceted models that are relatively smooth and error free.

This approach can be used for models with topology optimization results from Mechanical which can be brought in and converted to a SubD hybrid model in Discovery. These models usually have groups/facet regions set on import.

Note: To create facet regions in Discovery, select the facets and then right-click and select Add Facet Region from the context menu.
  1. Import or create a faceted model.
  2. Use the tools in the Cleanup group in the Facets tab to ensure the model is smooth and watertight.
  3. Select the Auto Skin tool in the Reverse Engineering group of the Facets tab.
  4. The Select Faceted Body tool guide is active by default. Select the faceted body.
  5. The Select Solid Bodies tool guide is activated. Select the solid bodies which match the facet regions.
  6. Click Complete to convert the model to a SubD hybrid model.
    The facet regions are converted to a combination of traditional and SubD faces. The SubD hybrid model retains the traditional analytic faces such as planes or cylinders for regions that require precise topology. The remaining facets are converted to SubD faces which allow for flexible editing.
