Edit Make Periodic |
The MakePeriodic command removes kinks from a curve or surface.
|
Periodic curve |
A periodic curve is a smooth closed curve. Periodic curves stay smooth when you edit them. |
|
Periodic Surface |
Periodic surfaces are closed surfaces (such as a cylindrical surface) that can be deformed without developing kinks. Periodic surfaces are automatically created when the input curves are periodic. |
Note
- Periodic surfaces and curves deform smoothly without kinks.
- If a joined curve is made periodic, it becomes a single-span curve and can no longer explode.
- Use the Object Properties, Details to check whether or not a curve is closed and periodic.
Steps
- Select the objects.

Smooth |
Controls kink removal. The Smooth option is only available when objects have not been selected. YesSmooths any kinks in the curve and moves control points to make a smooth curve. NoControl point locations are not changed or changed minimally (only one point may move) and only the knot vector is altered. 
Smooth=Yes (left) and Smooth=No (right. |

The MakeNonPeriodic command inserts a kink at the start/end of a curve or surface.
|
Non‑periodic curve |
A non-periodic curve is a closed curve with a kink at the start/end of the curve. Deforming non-periodic curves near the start of the curve may result in kinks. |
|
Non‑periodic surface |
A 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. Non-periodic surfaces and curves deform with sharp corners at kinks. |
