# rounded_cylinder
Creates a rounded cylinder.
## Parameters
- `radius` : The radius of the cylinder. It also accepts a vector `[r1, r2]` . `r1` is the bottom radius and `r2` is the top radius of a cone.
- `h` : The height of the cylinder or cone.
- `round_r` : The sphere radius which fits the edges of the bottom and the top.
- `center` : `false` (default), z ranges from 0 to h. `true` , z ranges from -h/2 to +h/2
- `convexity` : See [Rotate Extrude ](https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/Using_the_2D_Subsystem#Rotate_Extrude ) for details.
