Hello, I am trying to create a figure of 8 groove in my cylinder could anyone steer me in the right direction to do this?

Please use this link for the model https://a360.co/38UQHeB

Many Thanks,

Yes thats right, but the cut-out needs to go in the shape of a figure of 8 not just straight around the radius, please see below of a real life part.

Thanks,

Not totally sure you mean this, if so, I sketched 2 circles above the face.

Made 3d sketch and Project > Project to Surface, those 2 circles, onto the curved face.

Create Pipe > Cut and select a circle - do both.

You could try Deboss command. with your sketch 6, 

Might help....

@CADDMR  Ok, your pic makes more sense.

Your file doesn't, I have weird things happening if I make the cuts at the end of the time line,

Took timeline back and made cuts early in construction of the part, the tools behaved, but as I don't "know" the file, 

same process, sketch a half ellipse, project to surface and then pipe cut, mirror.

The timeline for this component has two versions of icons in it, so you may know whats going on.

How about this? The only problem is emboss will not let you create a feature that's the same length as the whole circumference as a cylinder. So PI*diameter should work but you have to make it slightly shorter or emboss will fail!

If you put the feed hole through the missing section it would cover up the problem. See attached file.
