    Void Cut Two Walls

    i saw an interesting post in AUGI today, thought maybe better to post here too (more top guns here!).

    this is the issue puzzled me for quite a long time.

    see attached RVT, i simplified window family and replaced opening cut w/ void, see the results for different cases, sorry for using RME instead of RAC as i'm now working in MEP firm.

    the reason i want to explore in depth here is that i wrote an API before for my previous company (home builder) which will automatically create sidings for stud walls -> case 4, but window's void won't cut through 2nd wall (siding) unless you join 2 walls -> case 5, the most interesting thing is that it do cut through 2nd wall even though 2 walls are not joined -> case 2 & 3.

    since joining 2 walls are not available in current API (wish i'm wrong!?), i have to do much much more complicatied coding -> basically get (siding) wall profile w/ all openings included.

    i don't know if anyone have better solution or workaround before my API wish can be realized, 2013 perhaps?

    How in the heck did you get the windows to cut both walls in case 2 & 3 ?? I Can´t replicate this in any way...

    BTW, have you tried with the new (2012) "Cut with voids when loaded" ?

      If you add a 2nd wall and then stretch it around until it contacts the window, when it will cut. Then stretch it away, and it 'stays cut'. Its all so trial and error, isn't it?

      See attached, the one I did.

        in fact, i didn't do anything in case 2 & 3 like B Arch did, i just make sure its angle between 2 walls is small enough, i did test long time ago using RAC, don't remember if it's 2011 or 2010?

        Munkholm, i just tested w/ new (2012) "Cut with voids when loaded" w/ RME 2012, doesn't work as case 4 is still the same.

        perhaps Autodesk people can explain why case 2 & 3 are OK but case 4 is not OK?!

          be sure that "Cut with voids when loaded" method is done with a facebased gm family that has a void inside that cut the face. Than in project use cut tool between void an walls. I hope i remember well.

              Very cool Gaby! Thanks :beer:

              Guess the solid used to cut the wall, could also be created in a new custom subcategory, and the visibility controlled with VG or Filters - But very cool trick! :beer:
