Hi Salil

Thanks for posting in the Community!

At this time there isn't an automatic shape counter tool and for this reason you would need to count the shapes yourself.

However we're always looking for ways to improve Lucidchart and your feedback is the best way for us to do that. Would you mind adding your idea to our feature request form? Ideas and feedback submitted to this form are passed on to the Product Development Team for their consideration.  

Thank you!
