Rotate Point Symbol with Line Bearing

[LarryAdgate]

My previous request for a discussion on this issue did not work out so I will try again. Thank you to those that weighed in previously. 

For the purposes of rotating a point symbol,  I am looking for a tool that will read or calculate Bearing data of a line feature class and then insert the data into a ROTATION field for a point feature class. I have attached a sketch to help illustrate what I am trying to achieve.

Thanks,

Larry Adgate

Link to previous thread so people don't reinvent what was previously proposed.

Your options for rotating point symbols are like below, neither of which follow your example. The script Dan references uses the Arithmetic option (or at least, I think it does) If there is a problem with the script, please respond in that thread.

As I'm not exactly familiar with the possible types of bearing, can you provide a complete example of which type of bearing you're looking for? I'm finding examples where direction is also incorporated (e.g. 10.5 degrees N of E vs. 10.5 degrees E of N), which won't be described by a number alone.
