Flip, Flop, Fly Apart Panels: A Workaround

[Edit: this bug is fixed in current web updates]
You've just finished doing Dave's excellent tutorial on dividing and paneling a form in Revit, it looks awesome, now you want to make some renderings to put on your Grandma's Ceiva. You load it into the Revit project environment, place and . . . .

[Cue sad trombone.]Mwa-mwa . . . all your panels have blown off! Perhaps you might write a haiku:

Expensive Panels
Drifting Autumn Leaves in Spring?
Revit Has Some Bugs

Indeed, this is a bug . . . sorry. Panels that have the "flip" OR "mirror" parameter checked in the divided surface properties dialogue will blow off the form when loaded into the project environment.

However, the unlikely workaround is this: If you use BOTH MIRROR AND FLIP. . . no problem! So as long as you are not picky about a left/right aspect of your panel and are simply trying to make an inside/outside distinction, you are back in business.

  1. Hi! That is cool!
    And how about closing gaps on the border of curtainwall in David`s tut?
    Is it possible?

  2. Yes, it's possible to close the gaps . . . a couple options. The first is to use "partial" setting in the divide surface instance properties in the "border tile" parameter. This will yeild panels sliced at the edge. Another option is to design special border panel conditions. For instance, using the hexagon panel template, make a panel that only uses four of the points. Set the divided surface to "overhang" in the border panel condition and load this new panel into the edge conditions where it is appropriate.

  3. Hey Zach, that's very helpful..........I was having exactly this problem! ;)

  4. Thanks a lot, but in my case I have something like 800 panels at the curved edjes and it will kill me to do it one by one each time I modify something in the surface!!!!
