Im quite new to surface modelling, but I want to give it a shot. My goal is to make cover panel for this wall unit (it needs to be fully covered):

As you can see there are many complex shapes. Now what I'm asking in this thread is:

1. What do I need to notice before I start? Any hints?

2. Where should I start (easiest surface, from the front end.. ?)

3. The cover panel should be about 3mm offset from the original surface

I hapily receive any question, free discussion etc.. about this topic.
