The follow code works when it's the original name Point. But renaming to StartPoint throws the following error.

Code: Select all

(X1, Y1, Z1) = (doc.getObject('Point').Shape.Point.x, doc.getObject('Point').Shape.Point.y, doc.getObject('Point').Shape.Point.z)

###### That works.

Is it not allowed to do renaming?

line 84, in <module>
(X1, Y1, Z1) = (doc.getObject('StartPoint').Shape.Point.x, doc.getObject('StartPoint').Shape.Point.y, doc.getObject('StartPoint').Shape.Point.z)
<class 'AttributeError'>: 'NoneType' object has no attribute 'Shape'

You changed the Label, not the Name. FreeCAD controls the Name. https://wiki.freecadweb.org/Object_name ... 0document.

Check

Code: Select all

doc.getObjectsByLabel('StartPoint')[0]

Changed to:

Code: Select all

(X1, Y1, Z1) = (doc.getObjectsByLabel('StartPoint').Shape.Point.x, doc.getObjectsByLabel('StartPoint').Shape.Point.y, doc.getObjectsByLabel('StartPoint').Shape.Point.z)

Error:

line 86, in <module>
(X1, Y1, Z1) = (doc.getObjectsByLabel('StartPoint').Shape.Point.x, doc.getObjectsByLabel('StartPoint').Shape.Point.y, doc.getObjectsByLabel('StartPoint').Shape.Point.z)
<class 'AttributeError'>: 'list' object has no attribute 'Shape'

I am going to try a couple of other things.

Edit tried:

Code: Select all

(X1, Y1, Z1) = (doc.getObjectsByLabel('StartPoint')[0].Point.x, doc.getObjectsByLabel('StartPoint')[0].Point.y, doc.getObjectsByLabel('StartPoint')[0].Point.z)

Following: https://wiki.freecadweb.org/Object_name ... e_or_Label

Error:

'

line 86, in <module>
(X1, Y1, Z1) = (doc.getObjectsByLabel('StartPoint')[0].Point.x, doc.getObjectsByLabel('StartPoint')[0].Point.y, doc.getObjectsByLabel('StartPoint')[0].Point.z)
<class 'AttributeError'>: 'FeaturePython' object has no attribute 'Point

Maybe I can't rename a point, was hoping I could.

Sorry another edit:

I believe I got it, some trial and error:

Code: Select all

obj1 = App.ActiveDocument.getObjectsByLabel("StartPoint")[0].Shape.Point.x
obj2 = App.ActiveDocument.getObjectsByLabel("StartPoint")[0].Shape.Point.y
obj3 = App.ActiveDocument.getObjectsByLabel("StartPoint")[0].Shape.Point.z
print('ob',obj1)
print('ob',obj2)
print('ob',obj3)

Seems you have to do x,y,z separately.

Seems you have to do x,y,z separately.

Not true. Look at what you typed.
Use command completion to test your code statements and you wont make these errors.

I believe I got it, some trial and error:

good, exploring things in fc-py-console along with printing here and there carries great mileage. (so does reading error messages ).

"Seems you have to do x,y,z separately."

not really, there is a difference...

Code: Select all

doc.getObjectsByLabel('StartPoint')[0].Point.x
vs
doc.getObjectsByLabel("StartPoint")[0].Shape.Point.x

btw, there is a shorter way to grab individual coord-components

Code: Select all

x, y, z = list(doc.getObjectsByLabel("StartPoint")[0].Shape.Point)
