![]() Ideally, you would aim to use the fewest amount of polygons to complete the desired geometry. Thus when converting a NURBS model to mesh, you must define the resolution at which to replicate the original geometry using simple planar polygons. 3D scan using only five toolbar buttons of its Windows-style user interface. NURBS (non-uniform rational bsplines) volumes are usually computationally much heavier than meshes, and therefore meshes are used to create file paths for 3dprinting. In no case does photogrammetry deliver a ready-to-3D-print, watertight mesh model. The main difference between a NURBS surface and a mesh is that the former is defined by curve functions rather than simple planar polygons. ![]() If your 3d model was carefully built in Rhino3D using NURBS geometry, the first step in preparing a print file is to convert the model into a mesh using the “mesh” command.Remember to choose Naked Edges in the list of ShowEdges command The open surfaces are shown with purple edges in Rhino after you use ShowEdges. The image below shows an open object vs a closed object. After you finish modeling, the first thing you should do is use ShowEdges command to make sure the object is closed.Boolean (split/union/intersection/difference).List of useful commands to create closed NURBS volumes:.
