![]() ![]() Next we need to convert the Subdivision model to NURBS surfaces. As you can see, a very nice subdivision model was created from the mesh(polygon) object. The rest of the options were left as defaults. For the example shown, Level option is set to 1. With the mesh selected, execute the ToSubD Command. For this tutorial, the mesh model was created in Blender and imported in Rhino as an OBJ object. The following steps describe a generic process of converting a mesh model to Sub-division format, followed by conversion to NURBS.īelow screenshot shows a mesh model in Rhino. Here’s a video demo of the Sub-division capability of Rhino 6. Traditionally, mesh-based models do not have the required accuracy for mass-manufacturing. This capability is extremely powerful as it allows for the creation of models that can be down-streamed to engineering programs such as Solidworks, Solid Edge, Creo and other applications that take NURBS-based data such as STEP and IGES. The advantage of Rhino’s Subdivision modelling technology is that, unlike non-CAD 3D programs, Rhino-based Subdivision models can be converted to NURBS (Non-uniform rational B spline). This method is popular with non-CAD 3D modelling programs such as 3DSMax, Lightwave and Blender. What is Subdivision modelling or SubD in short? It is a method of creating smooth models using a cruder polygonal or mesh model. ![]() ![]() What is exciting about future versions of Rhinoceros 3D is that it will have its own Subdivision modelling capabilities.
