Hello everyone,

Blend ver. 2.7

Show what you have and describe what you want in better terms! Note that in 3D the term ‘smooth’ hass a very specific meaning. If you mean rounded that’s something else. Anything can be smoothed, even a cube or a pyramid, because it refers to how the edges are drawn on screen. This is done using the smooth button in the toolbar. If you want your object to be rounded use the bevel tool or modifier. (ctrl B or the add modifier command)

Where would the smooth Button be located in ver 2.7, seems like it has moved
