 - Make the generated object visible 
 - try to make the design as modular as possible. for example, if i need to generate a cup, make the cup body as one feature in design tree and handle as other feature. in this way, i can edit the dimensions of both separately.
 - There is no built-in Part.makeTube function in FreeCAD. You're trying to create a hollow cylinder (tube) directly with parameters like outer_radius, inner_radius, height, but FreeCAD expects shapes, not numbers.

+- When converting a Part.BSplineCurve to a wire, do not use .toWire() directly (it does not exist). Instead, convert the spline to an edge with .toShape() and wrap it inside Part.Wire([ ... ]).
+    Example:
+    wire = Part.Wire([bspline.toShape()]) 
+- To create ellipse profiles, do not use Part.makeEllipse(). Instead, create a Part.Ellipse(), set the MajorRadius and MinorRadius, then convert it to a wire:
+    ellipse = Part.Ellipse()  
+    ellipse.MajorRadius = width / 2  
+    ellipse.MinorRadius = height / 2  
+    wire = Part.Wire([ellipse.toShape()])
+- Sweeping Profiles Along Paths
+    For sweeping profiles along a path, use the makePipeShell() method on the path wire instead of a non-existent makeSweep(). Pass a list of profile wires, and control solid creation with parameters:
+    pipe_shape = path_wire.makePipeShell([profile1, profile2, profile3], makeSolid=True, isFrenet=True)  
+- Handling PipeShell Solid Creation Errors
+    If sweeping results in BRepOffsetAPI_MakePipeShell::MakeSolid errors, try creating the pipe shell without forcing a solid first (set makeSolid=False) to debug geometry issues:
