Hello Commenter-3

The fix is on its way to OCCT master.

I would like to thank you for the link to the patch. Unfortunately, it has a mistake: the addition along cone's axis should be done if U derivative is 0 only. Please, take a look to OCCT commit 54b67d8e7bd80263f28ff009ff6eadc4cbd10bcf.

Best regards,
