Hi, I'm following the masterclass tutorials and I'm doing the candle holder at the end of M02. When I try to do a boolean effect the way the narrator does it, mine has a different result. I have a sphere that was cutout and the boolean is treating it like it's solid all the way through instead of like a cup how I have it. The cylinders are supposed to be cut away and leave holes in the cup like sphere. Any ideas? Here's the hip file. Thanks!

Hi there!

First, you cookie is set to Union, ofcourse you know this.. but it is suppose to be at A minus B.. what you should see now is that your boolean extruded a hole inwards this is not what you want..

One thing I noticed was that your tubes are all intersecting eachother, first resolve this by moving the center in Z by -2.6 (thats what I used).

The reason why you get more of a extruded effect is because object A is not a closed object, you've extruded it, but it does not have a thickness because you forgot to check the box “output back”, when you check the box you should have a thickness in object A.

I hope this helps!

Yeah, I forgot to change the cookie option before uploading. The output back was exactly the problem! Thank you!

TRUE.
