This drawing is very blurry because the resolution is so low, only 488 pixels wide.? It should be at least 1024 wide.? Unless somehow you're reducing the resolution before emailing, you should be able to get an improvement by setting this drawing to be a true attachment, not inline as you have done this time.
Recently you attached a PDF which fixed a similar problem.? I'd like to see what happens if you try the true attachment method, though.
I'm a moderator of one or two of your other machining groups, amd have several groups.io of my own, so I have experience with this kind of thing.? Email me direct if you want.
