I want to perform a really simple boolean as shown below:
However, I get this as a result:
Rather than boolean-ing all of the cylinders, it only does it for one. I have no idea what's causing this. Can anyone take a look at my file and possibly help?
Booleans can be extremely finicky about their placement sometimes - often all you have to do is change the "cutter" object's placement a little. Unless the position must be EXTREMELY accurate (No more than 0.001 units off), this can usually serve as a solution. Case in point: I was able to achieve this result by rotating the small cylinder group 0.001 degrees on the Z-axis before applying the boolean:
Too close vertexes is not friendly for boolean to work properly:(
The key is to avoid too close vertexes. There are two methods below.
Use individual origins to shrink all cylinders a little bit, you'll get what you need.
You can also rearrange the topology of the base part, more or less subdivision.
