Hello Sunil,
Thank you for posting your question in Bentley Forum.
Before creating any strings in MXRoad, you need to Check on Strings Naming Convention as it is not possible to use MXRoad on model that do not follow the standarad string naming convention. Hence please create strings with string naming convention to be checked on.
1. Go to Tools > System parameters > String Naming > String Naming Convention should be checked on.
2. Also while creating project on MX Project Start Up panel the String Naming Convention to be Checked on.
Regards,
