Hi Alex.

I shall give that a try. Just so you know, I'm not very good with radians. I learned them at school, but until now, haven't needed to use them. It's amazing what you can forget after 35+ years since leaving school!

I'll see if Windows default scientific calculator has something that will help. LOL

I have the CameraDefinition all set. It was just those angles that had me beat. I'm off to continue my task.

Thanks again.

Mark
