The Mesh objects can be manipulated by adding new facets, deleting facets, importing from an STL file, transforming the mesh and much more. For a complete overview of what can be done see also the [[Mesh Module]] documentation. A mesh object cannot be added to an existing document directly. Therefore the document must create an object with a property class that supports meshes. Example: |

Gli oggetti mesh possono essere manipolati aggiungendo nuove sfaccettature, cancellando delle sfaccettature, importando da un file STL, trasformando la rete e in molti altri modi. Per una panoramica completa di ciò che si può fare vedere anche la documentazione del Modulo Mesh. Un oggetto mesh non può essere aggiunto direttamente ad un documento esistente. Pertanto, il documento deve creare un oggetto con una classe appropriataa che supporta le mesh. Esempio:
m = Mesh.Mesh()
... # Manipulate the mesh
d = FreeCAD.activeDocument() # Get a reference to the actie document
f = d.addObject("Mesh::Feature", "Mesh") # Create a mesh feature
f.Mesh = m # Assign the mesh object to the internal property
d.recompute()
