I started to use Rhino recentlly, and i have a small problem, maybe someone can help me out?
The problem is that it will not cut the ring out of the cilinder??? (black design in the link)
It works with all other solids but not with this one??? i don’t know why??
Now i use the Chamfer tool, it worked, but it is not a constructed shape…! Therefore i need to know wat i did wrong??
I’m surprised this would work anywhere. If you call “What” on the blue object, you can see it has edge tolerances of nearly one unit. You can also see how bad it is by exploding and rebuilding the edges. Please explain exactly how it was created so we can fix the problem in the creation code.
We are working on tests to detect bad geometry like this that can cause problems further down the line. We are also developing better feedback from boolean operations to indicate where and why failure occurs.
Thank you VERY much for this tip!! I was STRUGGLING with a boolean difference and it was kicking my behind. This FAQ about boolean difference allowed me to solve this on my own and gave me better insight into how it all works so I think I will always have the tools now.
