2 questions

Hello, I think Zbrush is a wonderful tool but because of my job and family life I often go 6 months without having a chance or need to use it. it seems I have to completely relearn it every time that happens. When I was last using it the Classroom portal had many more tutorials available than I can now find. They were very very useful to me but now I cant seem to access them. Can anyone tell me if those are simply gone or what I need to do to get to them?

2nd thing is: I m working on metal casting a few simple motorcycle parts, mostly domed dish shaped covers. I have some bas relief meshes I would like to put on the convex or outer side of the dome but would like to keep it at a more or less constant height across the arc of the dome. I am not sure i explained that correctly. If you look at a coin it is more or less constant because it is on a flat surface. I would like to have it look like it was placed on flat and then the flat part was domed with it on there . What Rhino’s flow along a surface should do but I am not able to get it to put it any where near where I want it.

Is there a method perhaps with zproject that would do this? Or perhaps alphas? i dont want the relief standing out more as the surface recedes or less as the surface comes toward you. i want it to follow the curves as if laid upon it in a flexible state.

Thank you for any help on both issues.
