Actually I have to dynamically add attributes to a object. I am
writing python script for FreeCAD software. I am using loop to create
multiple cylinders and I am writing following code-:
cyname = "Cylinder"
FreeCAD.ActiveDocument.addObject("Part::Cylinder",cyname)
FreeCAD.ActiveDocument.cyname.Radius= .5
FreeCAD.ActiveDocument.cyname.Height= 10
And I am getting this error-:
AttributeError: 'App.Document' object has no attribute 'cyname'
Indeed.
But when I use Cylinder in place of cyname, I am not getting any error.
Of course.
Please help.
I don't have FreeCAD installed, I won't install it, and I'm not going to
read FreeCAD's doc neither, but you may want to check whether
FreeCAD.ActiveDocument.addObject actually returns the newly created
objet (which would be a sensible behaviour). If so, you'd just have to
keep a ref to this object, ie:
cylinder = FreeCAD.ActiveDocument.addObject("Part::Cylinder",cyname)
cylinder.Radius = 0.5
# etc
Else, you can always get this ref using getattr, ie:
FreeCAD.ActiveDocument.addObject("Part::Cylinder",cyname)
cylinder = getattr(FreeCAD.ActiveDocument, cyname)
cylinder.Radius = 0.5
# etc
And while you're at it, you could save on both typing and execution time
by keepin a ref to the document object itself:
doc = FreeCAD.ActiveDocument
for cyname in ("cylinder1, "cylinder2", "cylinderN"):
doc.addObject("Part::Cylinder",cyname)
cylinder = getattr(doc, cyname)
cylinder.Radius = 0.5
# etc
