How to model a bee's segmented abdomen I modelled the back of a bee using subsurface modelling.



I want it to have 'bumps' like this:



I did the above by duplicating the object a lot of times and then made shapes to use as a cut for the boolean modifier.
While the result looks 'ok' to me. Making changes is a real pain.

I also tried using a latice but  that didn't turn out well either.

What would be a good technique to do this?

Here the file in case it helps to try on the actual model.
You can use edge creases to sharpen edges when using the subdivision surface modifier, and simple bevelling and scaling to generate this effect.

Start with a subdivided capsule with a topology like this:



Select an edge where you'd like to create a segment in the bee's abdomen:



Bevel the edge using the shortcut CtrlB, then move the cursor slightly to create a small bevel.



Select the rear edge.



Scale it down.



Select the front edge, open the options panel with the shortcut N, then crank up the crease to around 0.75.



Finally, you can play with the scale and position of the edges of each segment, and repeat this process to create the segmented abdomen.
