Another unique command related to insertkink is non-periodic surface.

non-periodic surface is a closed surface with a kink at the start/end of the surface. Deforming non-periodic surfaces near the start of the surface may result in kinks. Non-periodic surfaces are automatically created when the input curves are non-periodic.

 MakeNonPeriodic

Makes a periodic curve or surface non-periodic.

Steps:

Select the objects.

The MakeNonPeriodic command changes a periodic surface or curve into a non-periodic surface or curve. Non-periodic surfaces and curves can develop kinks when deformed.
