How to find the intersection with project

Hello,

I have a .txt file referent to the plate boundary. I have two station coordinates (lat/long) and a back-azimuth value. I need to find the coordinates along the plate boundary in which the line baz intercepts the plate boundary. I tried with ‘project’ command, but I am unsure if something is wrong. Here is the command:

gmt project fault.xy -C-10/-10 -A318 -Fxy

The current output information is the same coordinates xy of the fault.xy file.

I will be happy for any help/suggestions. :slight_smile:
