Surface difference (trim?)

Hello everyone,
I am trying to trim the gray surface with the purple surface but I haven’t been successful with any of the commands I’ve tried so far.
What can I do? Thanks in advance (11.0 KB)

Region Difference suppose to work, but not the case…There are probably some tolerance issues.
BTW, you could try another method such asSolid Difference like the attached.
It’ll take some time to open it. (13.6 KB)
