Obiectele Mesh pot fi manipulate prin adăugarea de fațete noi, ștergerea fațetelor, importul dintr-un fișier STL, transformarea plasei și multe altele. Pentru o prezentare completă a ceea ce se poate face, a se vedea de asemenea, documentația Mesh Workbench. Un obiect de plasă nu poate fi adăugat direct la un document existent. Prin urmare, documentul trebuie să creeze un obiect cu o clasă de proprietăți care acceptă ochiurile poligonale de plasă. exemplu: 

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()
