    Question in how to lock the void extrusion on curve path ?

    Hi everyone , first of all my technique was to array the void extrusion then ungroup it (because when it is grouped it can't be locked to sweep path i know i will lose the feature of numbering how many voids ) so i un-grouped all void extrusion on the left and right side and then associate it workplan to sweep curvy frame path.(so when i changing the width it flex without complain).

    Now my question how i can lock the void extrusion on curvy path, i need when i change the height and width this void extrsuion on the top do nto scatter ( i attached it to sweep workplane but do not work).
    please help ,

    You shouldn't ungroup the arrayed elements... Keeping them grouped can work, if done properly.

      it does not work when i constraint them to the sweep frame , the programe complain and fail -- but with ungrouping and select them all and associate its work plane to sweep the two sides flex well with changing width or height of window. the problem is on the top i do not know how even i can do it when i do not know how to do it array constraint on the right and left sides!!

      To be frankly with you , my knowledge in family editor
      is that i can construct rectangle and lock them to refrence planes and make length ,width,height ,arraying with numbering giving them parameters
      and modifying existing elements of library of revit to fit my needs.
      more than knowledge above, i do not know how to deal with curves in family edito or lock like those arrayed voids with sweep (i only see programme complain

      i will attach my window so someone can discover my problem or help me into how to constraint them

        Maybe I was a little to fast... Or well, you´d need to keep them grouped alright, but you´d also need to use nested families (several levels), and a ton of formulas to make it truly parametric.

        Take a look at the attached example, which will let you change just about everything by adjusting parameters. It even checks for uneven amount of stones on the arc, and corrects it automagically if it´s even, so that the coinstone is always in the center.

        Didn't make it completely idiot proof, so it WILL break if the arc becomes too large compared to the width, etc. etc.
        And if I were to use it in a project, I'd also make some adjustments to the stones at the mitering corners, to make them all at equal sizes.

          Well i used nested family method but why the arrayed void extrusion did not cut the geomtry ?

            I used generic facebased families for the nested voids... Believe that may be your only option in 2011, while 2012 will have alternatives.

              well i used generic face family , but do you mean that the void extrusion can not cut in revit 2011 and able to do it in revit 2012 !!!!

                If you used a facebased template for the voids, you probably just forgot to use the "Cut" tool, to cut the void out of the dummy face in the nested family?

                No problems with 2011 (when using facebased), Have you tried opening the above family? Have a peak at the family, and not least the nested families... Maybe you'll get some inspiration

                  Munkhlom i made another type of trignomtric arch according to the pdf attached which is more flexible can you apply the void face into this attached arch

                    What you posted above pretty much looks like the simplified version that I later posted in the Formula thread....

                    Implementing the voids is not something that I can do in 2 minutes, and since you've already been given the techniques in the above posts, I think you should give it a try yourself.
