hey im working on a tutorial and ive stumbled upon another problem that i cant seem to quite fix.

im creating an aeroplane, ive made polygon cylinders for the windows and ive combined them all.
i used the boolean difference tool to subtract the difference from the plane and the tubes to create my windows. However the problem is the difference didnt seem to work completely...??? out of lets say 40 of the windows only 20 actually appeared

ive uploaded the image to give you guys an idea of what happened.

I tried to remake your problem. For me Boolean working with 1-2-3-10 merged cylinder. But not with 20.... I hate this boolean salution. Try to redo the missings, one by one
I would switch on the wireframe for modeling. It helps a lot
Shading / wireframe on shaded

Have you combined all the cylinders first? also have a edge going through the middle of them (I think bullet pointed that one out)............dave

Like this. but you wont end up with 4sided faces so you ve to work with the drilled windows a bit more.

You always have to do a clean up after using booleans, I would use cylinders with 8 sides less cleaning thats taking into account that you will smooth the mesh...........dave

i dont quite understand what you mean by 'have an edge going through the middle?'
ive tried the 1,2,3,10 method which didnt seem to work user added image

i even tried doing it 1 by 1. there seems to be a button or function that seems to be affecting my boolean:difference user added image

That way, after you cut out the hole, the hole is connected to the rest of the geometry with an edge (it's not a floating hole, which will cause major problems with the geo).

Don't be satisfied with what you can do but rather strive to do the things you can't do!

i figured it out, the reason why some of the windows were not working was because when i was duplicating my windows i accidentally duplicated a double of some of the cylinders for my windows which turned out to effect the difference user added image
