I'm relatively new to Blender, though rapidly getting comfortable (my background came from CAD/CAM systems). I have a relatively simple architectural project I'm working on where I am creating posts and railings. I first created a wrought iron post that I set in an array of three posts. Between the posts I put a top and bottom rail then added a single picket that I set to array. So far so good. I wanted to use a Boolean to animate that setup disappearing for a new use of the space by the construction contractor. I decided that it would be quicker (probably less overhead) to join the entire group and have the Boolean work on the group. When I join all the items, only the original item in the array appears, all the others disappear. I get very stubborn about finding a solution ( I wrote several technical manuals for CAD/CAM systems and tend to dig deep into programs for solutions first before turning to help). So, before I spend any more hours digging through manuals, and tutorials for something that may not exist, am I correct in assuming that only the original mesh in an array actually physically exists and the others are ghosts that can't be joined? Or am I missing a setting that lets me grab all of them? Thanks.
