Hii Everyone,
After long search about creating some python scripts that can access the Navisworks 2021 API, I found that using the Dynamo is NOT the best solution for that, I know that Dynaworks Package can handle some tasks but it can not go deep and take actions inside the Navisworks files itself.
Also I have seen the post of @Dimitar_Venkov (NavisPythonShell) but can not installed for Navisworks 2021 and I was tried to setup with more than one way but no Luck 
, So is there anyway to get Navisworks Python shell inside Navisworks 2021 ?? your help is much appreciated
