Hi Sarvani,
It is very important to include the version that you are using, this will greatly affect the answer that you receive, and therefore the effectiveness of that answer (for example, I tell you about a feature of IC615 that you don't have because you are using IC5141 - not too useful to you).
In IC615, if you select a net in the Navigator Assistant you can route directly from there using the built-in routing features (right mouse click and choose Route with Default Lookup, or Route with Wire Assistant Overrides).
Please provide more details and perhaps you can get a better answer.
regards,
Lawrence.
