You can work with the most suitable units for you or for the project while 3D modelling. This can be found at ‘File/ Properties/ Document Properties/ Units’. For example, if the model is bigger than the 3D printing area, the model must be adjusted.Īlso the desired dimensions of the piece should be coherent with the dimensions used while 3D modelling, as well as the units settings of the file that suits better to the project (inches, centimetres, millimetres). Objet dimensions and measures compatibilityĪn important factor to consider before starting your 3D model is the size of the object relative to the professional 3D printer that will be used to produce the piece. Global 3D printing 3D modelling process with Rhino Knowing the difference between these two 3D modelling approaches is important for a successful 3D printable model. It is different from a solid.Ī solid in Rhino is built with NURBS, which is different from a solid built through mesh 3D modelling.

Mesh: is a collection of vertices, edges and faces that define the shape of the 3D model.

Polygon: is a coplanar set of faces that build an open or a close volume.

Faces: is a closed set of edges that form a plane without thickness.

Edges: is a connection between two vertices.

Vertices: is a position along with other information such as color, normal vector and texture coordinates.

Solid: is a completely closed and joined polysurface that create the 3D model.

Polysurface: is a set of multiple contiguous surfaces that build a volume.

Surface: is a plane without thickness created between a group of closed curves.

Curve: are basically the points, lines and segments that make up the sketch model.

For this reason it is important to keep in mind and clarify some basic 3D modelling concepts. However for 3D printing in Rhino it is still necessary to create a mesh after the 3D modelling process. Rhinoceros works with a 3D modelling category called NURBS which is different than regular mesh 3D modelling.

Before you start 3D modelling anything using Rhino there are some factors that should be considered.
