Solid Element Operation.
Use it when ever you want to add or subtract any number of elements to other elements.
The relationship stays live so as you move your elements around they will adjust themselves to suit their new trimming position.
For example trimming the top of a wall so that it slopes with a roof or cutting part of an object away.
Do a search in these forums and you will find many posts about it and look it up in the HELP menu now you know what it is.
