Meshes can contain thousands of triangles (for example when generated by a 3D scanner), and solids made of the same number of faces would be extremely difficult to manipulate. But in FreeCAD we generally prefer higher-level objects, solids, that can carry much more information and allow for curved faces.Ĭonverting meshes to those higher-level objects (handled by the Part Workbench in FreeCAD) is not an easy operation. Meshes are quite practical for representing free-form geometry and big visual scenes, as they are very lightweight. Very often you will receive 3D data in a mesh format. meshFromShape ( Shape = shp, LinearDeflection = 0.01, AngularDeflection = 0.025, Relative = False ) Convert meshes to Part objectsĬonverting meshes to Part objects is a common operation. addObject ( "Mesh::Feature", "Mesh" ) mesh. getSelection () # a Part object must be preselected shp = obj.
Import Mesh import MeshPart obj = FreeCADGui.
