Modelling problem intersection of cube and sphere

[pailhead]

 

Spent whole last night trying to figure this one out. I need to model this orange thing, got it by booleaning a sphere from a cube, but, beside all the nasty edges and vertices from boolean its not what i want. I would like to have exactly 18 segments on each arc (edges of the object).

I guess then all of these vertical subdivisions should go from the bottom vertex?

Well, It's quite difficult or impossible to do this in boolean as the polygon/vertex alignment and numbers are certailnly out of control.

 

I suggest you try using polygon modeling (editable poly) and meshsmooth

 

or spline network and patch.

 

try find some basic tutorials about these.

I used to do things like this with nurbs and then control the tesselation after the fact.

Damn....

I know a lot more than basics of poly and spline modeling, but i thought there is an easier way around it.

But still.. i tried making 3 circles and then deleting all but that one quarter to get an arc with two bezier vertices, but when surfacing that the result wasnt what I thought it'll be. Instead of a part of sphere it had some corners or so...

Instead of usign Circles (4 bezier points only) you can use a Circular NGon with "n" points. This will give you enough points, and will not create steps in your arc.

But what do i do with the middle then?

I fear that ill end up using booleans, goodbye lightcape render
