Hi mantaskava,

NURBS are best when the design can be specified by 2D profile curves like you'd see in a blueprint. If it has holes drilled in it, that's usually another strong sign of being very good for NURBS.

Things that are kind of smooth and semi blobby tend not to fit in that category and will usually be better to do in sub-d or sculpting.

But some things can be in a grayish area that can be done with either but it will usually mean using a more advanced area of NURBS modeling dealing with freeform surfacing commands like lofting, network, and blend which has a higher learning curve than construction from just 2D profiles and using booleans.
