Hi Steve,

> Is the problem with the boolean, or with the sweep?

The problem is with the surface/surface intersection part of the boolean, the sweep is fine.

The cylinder / extrude happens to work in this case because either one of those gets created as an analytic surface subclass. Analytic surfaces can have some special case processing run for them during surface/surface intersection calculations in certain cases.

This is a good idea. I am planning on incorporating the geometry library update into the first v2 beta.
