Hi there ! I'm a newly with sketchup, and lately I been doing some practice, and there is a problem that I keep running into while practicing. That's modelling a model that has got curve edge on a slope or curve edge with an arc form to it.

I have an example of the model I been working on in my album.

any method in getting that edge to look like that in the photo, with the arc form shape and it has a nice round curve edge to it. Thanks
