So I was fiddling around with this today - a Tron Legacy ID disk (yes I'm aware it's not exactly a perfect replica, but the basic idea is there - which is good enough for learning purposes), after the triumph of following along with the Rhino tutorial, I figured I was on a roll...



And was wondering how to get the little inset detailing like you see here:



Basically what's the best approach to adding details like these insets (or whatever the technical term is for them) for example?

Hi Jim, you'll need to create a solid that is pushing downwards a ways into your object and then use that solid as the cutting object in boolean difference to cut it away from the main piece.

But since you want a piece that follows the same general shape as the original outer surface, you'll probably want to build that cutting object solid by trimming out a small portion of that original outer surface and then probably using Extrude to extrude that smaller surface fragment into the cutting object.

See this previous post for an example:

Thanks! I'll check those out.

By the way, the more I use Moi, the more I love the simple to use UI. It's hands down the most graceful UI I've ever used, I don't know specifically what it is, but you've really pared things down to their essentials, yet it seems like it's still a really powerful tool! I wish some of the other tools would follow suit (Blender, this especially means you!).

Thanks Jim, I'm glad that you are liking MoI's UI!
