![]() 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). 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.
