NX An error occurs when repeating "show result" > "undo result" in PMI region

After creating "Create Linked Mirror Part", when creating (or editing) a PMI Region, an error occurs if checking "Crosshatch" ON and repeating "Show Result" > "Undo Result" to preview the result.

Reproduced Steps:

1. Prepare a simple model and PMI Region(Circular) in a source part

2. Create "Linked Mirror Part" (Assembly Navigator > Select Component Node > Right Mouse Button > "WAVE" > "Create Linked Mirror Part")

3. (although this is not required) show the source part and the linked part via "View" tab > "Window Layout" > "2 Tabbed Groups"

4. Activate the source part and double-click the PMI Region from the MBD navigator (or Part Navigator) to enter edit mode.

  -1. Check "Display Crosshatch"

  -2. Check "Preview" and repeatedly select "Show Result" and "Undo Result“

As the sault, an error occurs as follows.

The behavior is due to NX problem and will be fixed in NX 2212.

Workaround :

If selecting "Show Result", finish editing the command without selecting "Undo Result".

If occurring the issue, cancel and redo the editing.

The issue occurs in all the NX version of NX 2206 Series and lower.

The issue occurs when using "Rectangular", "Circular", and "Annular" as PMI Region type.
