Pattern generation on Revit Wall cannot be reset after moving the pattern

[Anonymous]

step 1:

Generating pattern on the wall using the plugin command

step 2: Now moving the generated pattern using TAB key over the pattern , choosing the patter line and moving using  Arrow keys.

Step 3: When I click the plug in command to regenerate the pattern,the pattern is generated but its not resetting to the default position. Its still in the same moved position. I want to reset to the default fixed position. I have checked whether the pattern calculation is wrong but its calculating correctly for the whole face. but its not reflecting in the face as we moved the pattern before.

Is there any way where I can reset the pattern location  as before(like step 1) using Revit API??
