Hey Rajneesh

Thank you for posting in the Lucid Community! You can do a couple of things to help with the creation of your circuit diagram. First you can utilize our Circuit Diagram Shape Library. You can add this by clicking the + Shape Library menu on the left panel.

Next you can change the line connection by clicking the line endpoint menu on the top toolbar. This will allow you to place dots where lines cross. 

Hope this helps--please reach out with any additional questions. Cheers!
