Pete used a dozen different methods and evaluated the impact. It’s an interesting study of which product design techniques had the worst effect on regeneration time – and file size as well.
The most interesting lessons for me were the practices that I always believed adversely impact regeneration time, but don’t – or at least not anymore, due to improvements in the Creo Parametric software:
