[Mukundh]

I am using Blockstyler with super section. when a sketch is selected twice using super section then the error "Internal Memory Access Violation" message is shown. I have checked the log file and the below error is shown.

Functionality in Code:
1) Find the Part in current section. Make the part Displayed part.
2) Find the Sketch and Make active. (Orient to Sketch)
3) Select sketch using super section in block styler
4) Click Sketch button in super section and edit the sketch and click finish.
5) Now Blockstyler is shown again.
6) Repeat the step 4 now error is sbown

Can anyone tell me the cause of the issue. System details provided below.
