Interesting thing came up today while working the support line. Had a customer call in and say that he had split a wall to pull the ends apart for something, but now he needed to take the gap away and make the wall one again. Problem was that when he dragged the end back together, it cleaned up but didn’t join the walls together to make one wall. Since the wall was cleaning up the join, Disallow Join wasn’t turned on, so it was kind of a mystery. When I grabbed the wall though, I noticed in the Ribbon the Edit Returns for sweeps was an option. So as a test, we took the wall and edited the structure to remove the sweep and then tried the same thing…bingo, dragging the ends back together joined the walls into one again.
So, if you have a wall that has a sweep or reveal in/on the wall and you split it, it won’t go back to one wall if you try and drag the ends together. It doesn’t matter if it’s an integral (within the wall type) or an applied (outside the wall type) sweep or reveal…it will act the same. From the looks of it, Revit won’t join two sweeps or reveals back together into one continuous piece. Yes, it’s still one sweep or reveal in/on the wall, but you will have a joint where the wall was split.
