Hi everyone, I am enjoying a lot this forum
I have this archaic model of the Coliseum in Rome:confused:
I wanted to make small windows where the objects gray are, I apply the boolean modifier, do everything well and I don’t get what I want.
Maybe because the black object is only one and when I make more than one blender doesn’t let me.
Why have you created a new thread when you already have one already for this question?
When you say you don’t get what you want, what does that mean?
The boolean seems to work ok. By the way you have a duplicate mesh overlaying the one selected when you open your blend. It helps if you clean your model up. To spped things up you can join the arches into one object and the window cubes into another to just have one boolean needed. You do have overlapping meshes though.
