modeling detail into cylindrical surfaces

Something similar to this.
This type of mesh still baffles

Either way I'd like to "insert" detail into curved surface, I'm currently having a fair bit of difficulty.Any ideas?

theres a lot going on in this picture, but i assume you mean the detail in the heads of the belt wheels.

this can be achieved several different ways, the easiest of all being a boolean cut.

here is a simple demonstration in 3ds max:

jump to 3:50 in the video to see how the cut tool works.
the one drawback of using the boolean tool is that it tends to leave behind some really ugly geometry, and mess with the shading of your model. you will probably have to do a decent amount of cleanup after using this

Yeah, I noticed now that the original post wasn't that clear. I've updated the photo. I also now experimenting with boolean, as I no longer fear mesh cleanup . At the very least it gives me a starting point.

If you're modeling that kind of detail in subdivision, all you have to do is use more edges on your cylinder.

Hi xllr8,

First I would like to say, booleans are not the way to go, its just a bad, messy workflow. I mean it is possible to do some power-booleans then re-topo over the top of the model, but if you boolean and clean up, you are looking at some wasted time for this particular model IMO.
I am attaching an image with the stages I would use to model this. It literally took 5 minutes to make and the basic principle can be adapted/configured for your situation.
If anything doesn't make sense please post and I will try to explain further for you.

Hope this helps!
