I wish I could help you out. The key is finding the right method that works. When you do, it is remarkable how fast a complete set of 3d construction documents can be prepared. I'm on my ninth custom home this year with very detailed drawing sets - typically 50-60 sheets. 6 of those designs are already well under way in construction. All of them are fairly complex as well.
One of these days, I am hopeful to really document my approach in more detail, not just to help out those struggling, but to hopefully find someone that expands it much further.
If it helps any, I spend 90% of my time in Sketchup, and only 10% in layout. It's all in the prep time, so that you utilize Layout only for what it is intended......presentation.
