Like Veronique says: Amazing! Very nice work indeed.

While I'm at it:
I have been browsing some of your older posts for a while, and studied both your "tips & tricks" and your illustrations.
In this illustration it seems you have been able to create an overhang ( top image, left side), and I'm curious about how you managed that.
I have a project where I would like to visualise a similar structure.

Merry Christmas to you ( and to everyone else visiting here) !
