Drawing Sheet Delete error

Hi All,


   I am trying to delete the last 2 blank drawing sheets which are not required. But I could not able to delete them. I am getting some error message like "An attempt was made to decrement an already-zero ref count of an object." Please see the attached Image. Please let me know is there any other way to delete the last 2 blank sheets.


Thanks and Regards



Re: Drawing Sheet Delete error

Have you looked in the "Solutions center" database to see if someone encountered this before?


If not, I woud run part cleanup on the part

- start with a new NX session

- Run part cleanup setting all the "moderate" actions (or as desired)

- run it 3 times

- save part, close & reopen


If you didn't say they were blank, I'd try deleting all views from them before deleting the sheet.

Re: Drawing Sheet Delete error

Hi Ken,

Thank you for reply.

I have tried part clean up and restarted the system. It didn't work out. Then I realized there is some issue with Group which is having curves of Grid lines of the border. I couldn't able to delete them and its only issue with the last page. One good thing is that, it was allowing me to save the file. So Just I moved views which were in previous sheets to last sheet and deleted the previous sheet and changed the sheet no.
