Newbie question - Rail Revolve for curved-wall cuboid

 From:  argo

Hi,

Very new to 3D and just starting out with MOI.

As per the subject I am wanting to draft a box with curved walls. I thought of using Extrude but then the side-walls will not be curved.

I decided to use a Rail Revolve, with this method creating the attached. I am however surprised at the resulting lines throughout the object. Is this indicating irregularities of the surfaces or merely depicting the object in 3D?

Final aim is to 3D print the resulting box via the STL format.

Many thanks,
Brendan.



MOI is brilliant by the way, very intuitive!
