The dimension will appear on the arrows bar that was used to set up the file units, after selecting a starting and ending point for the line. You can find it at Dimension/ Linear Dimension. The “Linear Dimension” tool is Rhino’s technical drawing tool and can be used to find a precise measurement of the model. You can set up and personalize your grid at ‘File/ Properties/ Document Properties/ Grid’. The grid allows you to work precisely using the “Grid Snap” and the “Linear Dimension” tool. The main tool in Rhino used to visualize the size of your objects is the display grid in the background of the viewports. It is important to be aware of the measures at all times while 3D modelling as this will allow you to have absolute control over the size of your model. This is why you must change the units to millimeters no matter what unit of measurement you used to begin your model. So, for example, if you modeled a part of 5 cm × 5 cm × 5 cm using centimeters as a unit, you will obtain measurements of 5 mm × 5 mm × 5 mm when exporting your model in STL. Rhino unit settings are always interpreted as millimeters when imported into other programs. However before exporting you must always switch the units to millimeters and allow Rhino to scale the model.
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).
#Rhino 3d models professional
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.
