What is the easiest and the most blendtonic way to cut out this part:
Having the dimensions and full object video here:
As always: you use weird geometry… if the inner box was made in a proper way then his is easy… something like:
So you may wanna add additional (or don’t delete??) geometry to have less concave n-gons ??
Well not sure about the proper way but I did that by using a lot of the boolean modifier on my main Cube object to cut out many objects. Hence, my current object is more complicated than the one you showed there - this is why I also included the object .blend file. Maybe it would have been a lot easier just to download that then create another similar of your own.
Anyways, I was thinking at a similar solution to what I have done so far, so to create an object having the measurements I need and just use the boolean modifier again to cut into my main Cube object - just that it’s a pretty weird shape.
I tried to use the loop cut to get my 3.075 mm border but for some reason I cannot cut through that top part, I also tried to use the knife project to cut out the border around the hemisphere there in the middle but I cannot link it to the rest of the shape so I’m out of ideas.
It was quite plain to me that you used a boolean. That’s the reason i told you about manual modelling. But if you are better off with booleans then you are free to use them to construct your wishes in the first place. But of course you file doesn’t show us your way of contruction but only the result you ares stuck with.
Edit: And in the end you just did that: didn’t showed us how you did it…
