Unable to get holes in centre of object Not sure if this is an issue of non-volume geometry, but I'm trying to get holes in the centre of my object (film reel)and when I use a second boolean modifier in the plane object to difference of circle.001 it makes the entire reel disappear.
The issue is that the object you are using to cut the boolean is a mess... it is made out of a lot of overlapping surfaces.



Bolleans don't like that kind of geometry...

If you use a regular cylinder to cut the boolean everything works fine
