Waht I am trying to achieve is a long thin rod that smoothly takes the form of a
 Bezier curve. I can't seem to come up with a good way to do this.
- I can place small objects along a bezier spline but this seems a bit crude.
- If I sweep out an object using a bezier I guess it will produce a very
different solid from what I want.

Any ideas anyone?
thanks
Geo

A sphere_sweep is probably what you need...

Had a look at this and tried a few examples, seems to do the job!
