    Cutting voids through nested components; how?

    Hi all,

    I am creating a stud frame family comprised of nested components such as steel studs, track, sheathing board, insulation, and exterior finish. I have no problem in building a rectangular assembly of these components; however, I wish to cut a diagonal swath through the assembly to show the guts for presentation purposes.

    I have tried to do this by using a void extrusion through the panel and it actually cuts the components which were extruded within the family that the void is in; however, it does not cut any of the nested elements?

    I have also tried this using the cut tool; but not sure if I understand exactly that this is supposed to work.

    Any suggestions?

    Thanks,
    Jerry

    usualy a family void cuts only the geometry created from the same family.If I remember well, If you have your nested families as shared, in the project envirorment you can make an inplace void the same category as your family than you can cut between the void and the wanted nested items . It is possible to duplicate that void for every cut. Don't now for sure if this is the exact process but is possible in the project. I'm not at the computer right now. If you want it in the family, than every nested child needs a void. Or maybe you should experiment more with the new future "cut when loaded" ...maybe you can escape with the void only in the deeper nested level.

      That kind of detail shouldn´t be done in details only? It just seems too much to model.
      Have you tried "cut host when loaded" check?

        That sounds like an urban myth. Usually cutting families work on the project only.

          maybe i didn`t used the correct words . In a family you have an extrusion and a nested family. If you make a void in the same family and you want to cut something, the only thing you will cut will be the extrusion, because the extrusion was created in the same family as the void was. The nested can`t be cut. You have to go in the nested family and place the void there too.

          I`ve also made a small test few seconds ago between 2 generic families, one "nested/shared/cuts with void when loaded" that have a voidand it seems we can`t cut the geometry in the generic host family. So we can`t use "cuts with void when loaded" in the family envirorment. Only in the project.

          So for the OP there are 2 solutions:
          -Use the voids in every single family that needs to be cut.
          -Use an inplace void in the project and cut the nested items you need (the nested should be shared so you can select them) (EDIT LATER: NOT WORKING )

            As an alternative method to accomplish what I think you are trying to achieve, you could create a compound wall type, use Parts, then "peel" the layers back
            with the shape handles. Then lock the 3D view, and use material keynotes to annotate the 3D View.

            If you really need to show the individual studs and tracks, there are ways to do it--3rd party app/add-ins, adesk's framing add-in, etc., build a separate family, etc.
            But to me it's not worth the effort in a simple example--perhaps if the framing is complex it would be worth it.

            I created the attached example in about 4 minutes.

            No voids, cutting problems, nested/shared family problems, etc. A single wall element, broken into its components.

              Thanks guys,

              I believe that you have a good grasp of what I am dealing with.

              I am intentionally building the model as detailed as possible, as I intend to use this as a building block for other presentation work. I have created my own detailed family for the stud, track, panels and horizontal bar.

              I have attached a copy of the stud panel assembly that I am building. It has some nested components and some extrusions that were built within the family. The void, as shown here, only cuts the extrusions which were built within the family.

              I am a novice with revit, so not sure how well I am doing with this.
              All advice is accepted.
              Thanks,
              Jerry

                my mistake. Model in place voids don`t work in this situation. Create a generic model family with just a void. Make the family to have "cuts with void when loaded" checked. Than in the project cut between your family and the void family.

                  there is better idea you can create void from face base family and nest it into another family it will work i tested it before.:thumbsup:

                    Thanks,

                    This will work for what I need.
                    Still learning all the tricks and need all the help I can get.
