Boolean Difference not working
 

Hi, everyone I'm working on a ship that i'm building and i've run into a problem. I am trying to make windows in the sides of the ship using multiple cubes with boolean difference. I had done this earlier to see how it would look and it worked fine, since then i have added stuff to the ship and was ready to the put windows in, but when I click to do boolean difference, my ship and the cube I selected disappeared and I got an error message in my script. What should i do?

Unfortunately, booleans are not always the most stable or reliable of functions. I've yet to find a work-around or anyone who truly understands *why* booleans work some times and not other times.

I had this problem one time, and I performed a Mesh>Cleanup and it helped. Test around with the different settings to see which ones work, and don’t screw up your geometry.

hmm. well I got it to work but I had to subdivide my ship, for some reason I could only do boolean difference Once before it stopped working again so I just combined all the cubes together and that worked. Thnk you for your help guys, Ill keep that in mind next time I have a problem like this!
