Yes you deactivate the old workbenches.

Here the example code for edge classification def runEdges(): edgesA={} for i,e in enumerate(FreeCAD.ActiveDocument.Cut.Shape.Edges): t=e.Curve.__class__.__name__ print (i,t) k=None if t =='Circle': k=np.round((list(e.ParameterRange)+ list( e.Curve.Location) + [e.Curve.Radius] +list(e.Curve.Axis)),2...

To identify a subobject you need a key which is relative unique. I use for faces this: def pkey2(c,pa,pb,r): return tuple([c,r]+list(np.round(pa,2))+list(np.round(pb,2))) def getFaceKey(face): '''facekey for face type''' f=face typ=f.Surface.__class__.__name__ if typ == 'Cone': pk=pkey2('cone',f.Sur...

You can use the animation workbench

There is a way to use expressions to get the data from a spreadsheet into the parameters of the placer as expressions.

Microell2's macro would not work and gave the following message: " File "C:/Users/sandi/AppData/Roaming/FreeCAD/Macro/Curved_Development_Microell2.FCMacro", line 12, in <module> apex=face.Surface.Apex <class 'AttributeError'>: 'Part.Cylinder' object has no attribute 'Apex'". Thi...

Very nice design ideas at all. Thank you.

You cannot develope a sphere. Only faces with gaussian curvature zero can be developed. For such faces you only can split them into small segmets and make some deformation: example - the shell of an orange

This one should work on cones too : There is still an error in your script ?! here is my one sel = FreeCADGui.Selection.getSelectionEx() face = sel[0].SubObjects[0] f=face.toNurbs().Face1 sf=f.Surface startA=f.valueAt(0,0) apex=face.Surface.Apex r0=(startA-apex).Length r=face.Surface.Radius import ...

Nice to have this already.
If we adopt this to conic surfaces the most common developable surfaces can be flattend.
