# Hi Yorik, Hi Yorik, would you check the line 1777 in the file Draft.py ? Calling, e.g. Draft.makeDimension(Base.Vector(0,0,100),Base.Vector(0,10,100)) outputs: Traceback (most recent call last): File "input", line 1, in module File "/usr/lib/freecad/Mod/Draft/Draft.py", line 474, in makeDimension _ViewProviderDimension(obj.ViewObject) File "/usr/lib/freecad/Mod/Draft/Draft.py", line 1777, in __init__ obj.DisplayModes = ["2D","3D"] #obj.DisplayModesAttributeError: 'Gui.ViewProviderPythonFeature' object has no attribute 'DisplayModes' Change to obj.DisplayMode= ["2D","3D"] works for me.
