Nathan,
In general CAD terms, this would be best handled by a generalized sweep entity.
We’ve had that on our TODO for years. Not incredibly hard — very similar to
our extrude and revolve entities — but nobody has begun working on it. It was
proposed as a 2009 GSoC project, but Timothy basically spent the whole
timeframe working on surface of revolutions. Would have been a great GSoC
proposal this year or a fun project for someone to tackle on their own.
Cheers!
Sean
