Problem: modeling philips screw head using modifiers I am trying to model a screw head using boolean modifiers. I cannot get both tracks subtracted using solidified beveled faces. The second boolean operation fails if both tracks overlap (left) and succeeds if they don't. What is going on ?
What you could do is join both of your boolean objects into one mesh. Then you can apply the modifier. This might also happen because you didn't apply one before using the other.
