Block rotation

Hi all,
I hope you all doing well. Anyone can help me with a simple problem! I am trying to create a script that allows me to rotate the AutoCAD block around its reference point.
Please check the screenshot and thank you for any tips and support.
Kindly regards

using the GetParameterByName node

Dear @hosneyalaa,
Thank you so much for your support. Can you explain a bit about what I should replace/ remove from my script and to which node I need to connect the GetParameterByName? I am new to the dynamo, and I wish I had more knowledge to understand the node’s context and its mechanism.
Thank you for your understanding.
Kindly regards
