Hide the annoying "sketches" in swept blends?

[MechanicalAnimal]

dear forum members, I need a bit of help with this one as I can't find it in the tutorials anywhere. I'm self-taught with pro-e creo and am using parametric 2.0

the problem is, when I create swept blends, the sketches remain unhidden. They don't show only in 3d representations (which is annoying enough) but also in 2D drawings I create out of them, appearing as contour lines that shouldn't be there. I can manually "hide" them, but then they "show" every time I re-open the files. so every time I publish my drawings, I have to re-hide all the sketches. Is it possible to permanently hide them?

I have attached a picture of what I'm talking about here (a swept blend+shell with visible blue lines-sketches). Please help!

You should be able to control that with layers but I've not tried in Creo2.

The Help for this program was created in Windows Help format, which depends on a feature that isn't included in this version of Windows.

If you hide them, then switch to view the layer tree (instead of model tree) and save changes. Save the file & done.
