Q) When I write DWG files each layer gets created regardless of whether there is any data for it. Can I avoid this?

A) Doing a basic translation no, this can't be stopped.

However, if you can instead use the Feature Fype fanout (see www.safe.com/movies for a show about this) to drive the layer creation from an attribute value, you will not get any of the unneeded attributes created.

In such a case, you'd have only one output Feature Type (layer) on the right hand side in workbench, and you'd "fan it out" on an attribute that truly held the layer name. It shouldn't matter what you called the single Feature Type as there would be no layer created for it -- well, maybe, so it would be good to name it after a commonly occurring one anyway.
