Sweep command and "Path does not intersect profile" warning

[cshepard]

This has been something happening with the most recent version of Inventor and I am trying to understand why this warning is necessary, and what actually is the best practice for sweeping a profile along a path. For tubing in our assemblies, I draw, if not a basic extrude/shell, a profile representing the tube ID and OD, and then sweep it along a path that would represent the center-line of the tube. (More complicated parts will follow the same principle but use 3D sketches for the paths.)

As you can see by the screenshot, even though inventor can compute the solution, and provide a preview it still throws up this "Path does not intersect profile" warning. Clicking "yes" completes the sweep command and there is no further fuss or errors.

What is the best practice? What am I missing here? I've drawing simple bent tubes or other sweeped features like this for a decade, and only now it seems to be a problem.

So:

the bends that go away from where the path meets the edge of the profile need to be the outer diameter of the bend

the bends that go towards it need to be the inner diameter of the bend

the bends that go perpendicular to it need to be the diameter that you would have used for the symmetrical path

bends that are not orthogonal to the path ...    [Could you just use sin or cosine, or would you need an ellipse or something?]

(If you make a solid sweep and then make a second sweep to make it hollow then you avoid the message.)

(It's one extra click in the process to ignore the error message.)

[They'll get around to fixing this after they finish adding features (that may or may not be fully functional) (and then they'll break something else in the process).]

Hi Folks,

The defect should have been fixed on 2022. I cannot reproduce the behavior on 2022.1.

Many thanks!
