how to automatically update details such as part name,no,material etc in title block
The text in the title block needs to be linked so it will update.
The question is where you want it to update from. The most common location is from the metadata saved with the model. You can add and edit them from File - File Properties.
Adding links is not too difficult. Check the help file for "Link to Property".
