Answering Myself- On How to resize semispheres
-
okay. refer to the first 3 images.
i originally wants like this little idyllic hill. So i created a semisphere (and i learned how here: http://www.youtube.com/watch?v=A5ICHizei6M fast-forward to 0:38) but it seemed too steep. I wanted my little creations to be able to have picnics on that thing. So originally I wanted to cut off a part of my dome so i'd have the less-steep tip left- i placed the part I wanted off under the plane for the sake of demonstration.
I still don't know how to cut the rest of that dome off, but I realized I didn't have to- the scale option allowed me to make the dome less steep, just by pulling the little green box right above the dome's tip and pulling it down. Yes, yes, you're very welcome for sharing this bit of genius. End results in last 2 pics

Or if you wanted more natural hills (or maybe hills with flatter tops, or whatever) you could you the sandbox tools - for instance, create a sandbox "from scratch", draw your preferred plan outline on top of it (say a circle). Delete the excess from the outside, then use the smoove tool to get your preferred shape.

why thank you Jean Lemire, that was amazingly thoughtful. How did you get rid of everything under the intersection in scene 2? Sketchup refused to see the half sphere as anything but one fixed entity for me?
and sketchymick i actually wasn't aware that that option was even available, that i could just delete the excess around my circle.... thank you both!

Did you right-click "intersect with model"? I think that was the intention. This should put a line around where the plane intersects the sphere, actually adding edges on the sphere surface. Double click the face below, group and delete.
Also try turning hidden geometry on. With all the faces showing, you can delete portions of spheres

It'll work for any shape. One thing I forgot to mention is that if you do use the smoove tool in this fashion, take care not to lift or lower the edges of your circle, otherwise the edge of your hill won't be flat anymore, and won't join in nicely to the rest of your model(although you could use TIG's drop vertices plugin to drop all the edges back to the same elevation again if you wanted to do it that way).
You can of course modify other geometry using the sandbox tools. For instance, make a dome, then use smoove on it to deform:
or even make some custom domes using the cross-section of your choice:
